Abstract
Human 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2) are potential targets for suppressing pruritic skin inflammation in atopic dermatitis (AD). In addition, Staphylococcus aureus colonization and oxidative stress worsen AD skin conditions. We aimed to investigate anti-inflammatory activity, using 5-LOX and COX-2 inhibitions, and the anti-staphylococcal, and antioxidant potentials of several medicinal plants bio-prospected from traditional medicine related to AD pathogenesis. Essential oils and hexane fractions were prepared and analyzed using gas chromatography-mass spectrometry. Boesenbergia rotunda hexane extract displayed anti-Staphylococcus aureus (MIC = 10 µg/mL) and antioxidant activities (IC50 = 557.97 and 2651.67 µg/mL against DPPH and NO radicals, respectively). A major flavonoid, pinostrobin, was further nonchromatographically isolated. Pinostrobin was shown to be a potent 5-LOX inhibitor (IC50 = 0.499 µM) compared to nordihydroguaiaretic acid (NDGA; IC50 = 5.020 µM) and betamethasone dipropionate (BD; IC50 = 2.077 µM) as the first-line of AD treatment. Additionally, pinostrobin inhibited COX-2 (IC50 = 285.67 µM), which was as effective as diclofenac sodium (IC50 = 290.35 µM) and BD (IC50 = 240.09 µM). This kinetic study and molecular modeling showed the mixed-type inhibition of NDGA and pinostrobin against 5-LOX. This study suggests that B. rotunda and its bioactive pinostrobin have promising properties for AD therapy.

Abstract
The use of synthetic drugs to overcome bone ailments causes severe side effects, but the application of herbals is helpful in maintaining bone health and accelerating bone mending. Currently, there is no oral allopathic medicine to hasten bone healing, though folk and traditional practices have adopted herbal to fasten the recovery from bone ailments. Earliest recovery is a universally desired phenomenon, especially for elderly people where many more cases of traumatic injuries are common along the compromised body immunity. The computerized database search engines, such as Google Scholar, PubMed, ScienceDirect, Springer Link, etc., and textbooks were used to collect all relevant information about barks for bone mending activity published from 1990 onwards using certain keywords such as bark, folklore/ traditional bone healing practices, and phytopharmacology. The results obtained were compiled to make this review and related information is tabulated herewith. Traditional herbal bone healing exists in every society in the world. The plant barks of a few species (e.g., Ficus religiosa, Prunus cerasoides, Terminalia arjuna, etc.) have outstanding significance for bone healing because of their special chemical composition and novel properties to reduce swelling, pain, soreness, and speedy recovery of functions. Mostly bark extracts are rich in polyphenols, and minerals, represented with antioxidant, immunostimulatory, antibacterial properties, etc. There is a diversity of bark utilization for bone healing from different plant species, globally, of which only a few have been phytopharmacologically deciphered. Validated bark ingredients as medicine or food supplements are more useful due to the least side effects. Entrepreneurs have a scope to use bioactive obtained from plant barks that have not been scientifically screened till now. The research focused on the commercial application of plant barks as green medicine needs fingerprints of bioactive and clinically validated data including the concentration of biomarkers in the blood (IC50) for reducing the healing period. Phytopharmacological screening of barks used in folk medicine and synthesizing the therapeutics at mega quantities in industries is an array of hopes for sustainable utilization of natural resources. The bio-stimulating knowledge of certain herbal ingredients will be helpful in the development of synergistic formulations for rapid bone mending.

Abstract
Twenty-six eudesmanolides including six undescribed compounds were isolated from the flowers of Sphagneticola trilobata (L.) Pruski. Their structures were elucidated based on the interpretation of spectroscopic techniques, NMR calculation, and DP4+ analysis. The stereochemistry of (1S,4S,5R,6S,7R,8S,9R,10S,11S)-1,4,8- trihydroxy-6-isobutyryloxy-11-methyleudesman-9,12-olide (1) was demonstrated by single crystal X-ray diffraction. All eudesmanolides were evaluated for their anti-proliferative activities against four human tumor cell lines (HepG2, HeLa, SGC-7901, and MCF-7). 1α,4β-Dihydroxy-6α-methacryloxy-8β-isobutyryloxyeudesman-9,12-olide (3) and wedelolide B (8) showed pronounced cytotoxic effects against AGS cell line with IC50 values of 1.31 and 0.89 μM, respectively. Their anti-proliferative activities against AGS cells were exerted through a dose-dependent apoptosis pathway, as verified by cell and nucleus morphological assessment, clone formation assay, and Western blot analysis. Furthermore, 1α,4β,8β-trihydroxy-6β-methacryloxyeudesman-9,12-olide (2) and 1α,4β,9β-trihydroxy-6α-isobutyryloxy- 11α-13-methacryloxyprostatolide (7) performed significant inhibitory effects on lipopolysaccharide-stimulated nitric oxide production in RAW 264.7 macrophages with IC50 values of 11.82 and 11.05 μM, respectively. Moreover, compounds 2 and 7 could block the nuclear translocation of NF-κB and reduce the expression of iNOS, COX-2, IL-1β, and IL-6 to exert anti-inflammatory effects. This study provides evidence for the utilization of the eudesmanolides from S. trilobata as lead compounds for further research due to their cytotoxic potential.

Abstract
Although medicinal plants are beneficial, they also can be important risk factors for the development of acute and chronic kidney injury, as well toxicity of other solid organs. There are a lack of reports of adverse kidney events and drug interactions resulting from medicinal plants owing to a lack of professional surveillance and specific data on kidney toxicity, especially in low-resource settings. Within the context of increased medicinal plant use and lack of effective regulatory control, safety is a key priority issue. We review the benefits and adverse effects of medicinal plants with particular reference to nephrotoxicity encountered in the Democratic Republic of Congo in sub-Saharan Africa.

Abstract
B. crassifolia is a species that grows in various areas of Latin America. It was known to be useful for the treatment of different human ailments. The present work evaluated the neuropharmacological and analgesic effects of hydroalcoholic and dichloromethane extracts of B. crassifolia. The effect on the central nervous system (CNS) of both extracts obtained from bark, administered by the intraperitoneal route in mice, was evaluated by different tests: spontaneous motor activity, hole-board, motor coordination, pentobarbital induced hypnosis, and rectal temperature. Analgesic activity was evaluated using a hot plate test. Phytochemical analysis was performed by high-performance liquid chromatography (HPLC) using reversed-phase and gradient of elution. The hydroalcoholic extract (dose 0.5 g dry plant/kg weigh) administration caused an important reduction of the head-dipping response in the hole board test. A decrease in spontaneous motor activity test and a disturbance of motor coordination in the rotarod test was observed. The hydroalcoholic extract produced a significant prolongation of pentobarbital induced sleeping time. This extract prevented hot plate test induced nociception. The phytochemical analysis revealed the presence of catechin, epicatechin, and procyanidin B12. Therefore, this study revealed that the hydroalcoholic extract of B. crassifolia possesses analgesic and sedative CNS activity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sphagneticola trilobata (L.) Pruski is used in traditional medicine in Brazil for inflammatory diseases treatment including asthma. The diterpene kaurenoic acid (KA) is one of its active compounds, but whether KA activity could explain the traditional use of S. trilobata in asthma is unknown. AIM Investigate KA effect and mechanisms in asthma. METHODS Experimental asthma was induced by ovalbumin immunization and challenge in male Swiss mice. KA (0.1-10 mg/kg, gavage) was administered 1 h before the ovalbumin challenge. Total leukocytes, eosinophil, and mast cell were counted in bronchoalveolar lavage fluid (BALF), and lung histopathology was performed. Lung mRNA expression of Th2 and regulatory T cells markers, and BALF type 2 cytokine production were quantitated. NFκB activation and oxidative stress-related components in pulmonary tissue were measured. RESULTS KA inhibited the migration of total leukocytes and eosinophils to BALF, reduced lung histopathology (inflammatory cells and mast cells), mRNA expression of IL-33/ST2, STAT6/GATA-3 and NFκB activation in the lung, and reduced IL-33, IL-4, IL-5 production in the BALF. KA also reduced the mRNA expression of iNOS and gp91phox, and superoxide anion production accompanied by the induction of Nrf2, HO-1 and NQO1 mRNA expression, thus, exerting an antioxidant effect. Finally, KA induced nTreg-like and Tr1-like, but not Th3-like markers of suppressive T cell phenotypes in the lung tissue. CONCLUSION KA prevents antigen-induced asthma by down-regulating Th2 and NFκB/cytokine-related pathways, and up-regulating Nrf2 and regulatory T cells' markers. Thus, explaining the ethnopharmacological use of S. trilobata for the treatment of lung inflammatory diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sphagneticola trilobata (L.) Pruski is a plant species belonging to the Asteraceae family. Kaurenoid acid (KA) is a diterpene metabolite and one of the active ingredients of Sphagneticola trilobata (L.) Pruski. Extracts containing KA are used in traditional medicine to treat pain, inflammation, and infection. AIM The goal of the present study was to investigate the in vivo effects of KA (1-10 mg/kg, per oral gavage) upon LPS inoculation in mice by intraperitoneal (i.p.) or intraplantar (i.pl.; subcutaneous plantar injection) routes at the dose of 200 ng (200 μL or 25 μL, respectively). METHODS In LPS paw inflammation, mechanical and thermal hyperalgesia MPO activity and oxidative imbalance (TBARS, GSH, ABTS and FRAP assays) were evaluated. In LPS peritonitis we evaluated leukocyte migration, cytokine production, oxidative stress, and NF-κB activation. RESULTS KA inhibited LPS-induced mechanical and thermal hyperalgesia, MPO activity and modulated redox status in the mice paw. Pre- and post-treatment with KA inhibited migration of neutrophils and monocytes in LPS peritonitis. KA inhibited the pro-inflammatory/hyperalgesic cytokine (e.g., TNF-α, IL-1β and IL-33) production while enhanced anti-inflammatory/analgesic cytokine IL-10 in peritoneal cavity. In agreement with the effect of KA over pro-inflammatory cytokines it inhibited oxidative stress (total ROS, superoxide production and superoxide positive cells) and NF-κB activation during peritonitis. CONCLUSION KA efficiently dampens LPS-induced peritonitis and hyperalgesia in vivo, suggesting it as a suitable candidate to control excessive inflammation and pain during gram-negative bacterial infections and bringing mechanistic explanation to the ethnopharmacological application of Sphagneticola trilobata (L.) Pruski in inflammation and infection.

Abstract
The quality of health care in Mesoamerica is influenced by its rich cultural diversity and characterized by social inequalities. Especially indigenous and rural communities confront diverse barriers to accessing formal health services, leading to often conflicting plurimedical systems. Fostering integrative medicine is a fundamental pillar for achieving universal health coverage (UHC) for marginalized populations. Recent developments toward health sovereignty in the region are concerned with assessing the role of traditional medicines, and particularly herbal medicines, to foster accessible and culturally pertinent healthcare provision models. In Mesoamerica, as in most regions of the world, a wealth of information on traditional and complementary medicine has been recorded. Yet these data are often scattered, making it difficult for policy makers to regulate and integrate traditionally used botanical products into primary health care. This critical review is based on a quantitative analysis of 28 survey papers focusing on the traditional use of botanical drugs in Mesoamerica used for the compilation of the "Mesoamerican Medicinal Plant Database" (MAMPDB), which includes a total of 12,537 use-records for 2188 plant taxa. Our approach presents a fundamental step toward UHC by presenting a pharmacological and toxicological review of the cross-culturally salient plant taxa and associated botanical drugs used in traditional medicine in Mesoamerica. Especially for native herbal drugs, data about safety and effectiveness are limited. Commonly used cross-culturally salient botanical drugs, which are considered safe but for which data on effectiveness is lacking constitute ideal candidates for treatment outcome studies.

Abstract
Guatemala as part of Mesoamerica, is a region of high biological and cultural diversity, where several cultures have flourished. Since 1976, a project started for the detection, validation, production, and utilization of medicinal species for primary health care. It included several ethnobotanical surveys conducted among ten Guatemalan ethnical groups. The objective of this paper is to summarize the ethnobotanical surveys conducted in the country and review the literature validating the use of the most promising native species. From these surveys, more than 650 plant species used for medicinal purposes were detected and cultivation activities were conducted for some of these species. Initially, in cooperation with the multidisciplinary teams in Guatemala, and later with other academic institutions in Brazil, Costa Rica, Italy, Mexico, Panama, Spain and United States, in vitro and in vivo validation activities were performed, such as biocidal, anti-inflammatory, spasmolytic, immunomodulatory, antioxidant and other activities. A comprehensive literature review of the most relevant species was performed. Based on the traditional utilization and preclinical or clinical evidence, several national and international projects were conducted. The most interesting results include anti-candida (Solanum nigrescens), antimicrobial (Tagetes lucida), immunomodulator (Phlebodium pseudoaureum), anti-protozoal (Neurolaena lobata), sedative (Valeriana prionophylla), anti-menopause (Piper hispidum) activities and others. With this information and the reviewed literature, specific formulas were prepared for the treatment of different pathologies, leading to several products registered as phytotherapic in Guatemala. Concise updated information is integrated into mini-reviews for 15 species in order to inform about the properties, chemistry and potential use of these species.

Abstract
Polyphenols are one of the largest and most widespread groups of secondary metabolites in the plants world. These compounds are of particular interest due to their occurrence and the properties they possess. The main sources of phenolic compounds are fruits and vegetables, but lately, more and more studies refer to woody vascular plants, especially to bark, as an important source of phenolic compounds with a potential biological effect. This study aims to bring together information on the phenolic compounds present in the bark of woody vascular plants by discussing extraction methods, the chemical composition of the extracts and potential biological effects. The literature data used in this paper were collected via PubMed (2004⁻2019). Search terms were: bark, rhytidome, woody vascular plant, polyphenols, phenolic compounds, biologic activity, antioxidant, immunostimulatory, antimutagenic, antibacterial, anti-inflammatory, and antitumoral. This paper intends to highlight the fact that the polyphenolic extracts obtained from the bark of woody vascular plants represent sources of bioactive compounds with antioxidant, immunostimulatory, antimutagenic, antibacterial properties, etc. Future research directions should be directed towards identification and isolation of bioactive compounds. Consequently, biologically active compounds obtained from the bark of woody plants could be exploited on an industrial scale.

Abstract
INTRODUCTION Byrsonima species have been used in the treatment of gastrointestinal and gynecological inflammations, skin infections and snakebites. Based on their biological activities, it is important to study other organisms from this genus and to identify their metabolites. OBJECTIVES To determine the metabolic fingerprinting of methanol and ethyl acetate extracts of four Byrsonima species (B. intermedia, B. coccolobifolia, B. verbascifolia and B. sericea) by HPLC-DAD-ESI-MS/MS and evaluate their in vitro antioxidant, anti-glycation, anti-inflammatory and cytotoxic activities. MATERIALS AND METHODS Antioxidant activity was determined by DPPH˙, ABTS˙+ and ROO˙ scavenging assays. Anti-glycation activity was evaluated by the ability to inhibit the formation of advanced glycation endproducts (AGEs). Anti-inflammatory activity was evaluated using a murine macrophage cell line (RAW 264-7) in the presence of lipopolysaccharide (LPS). Tumour necrosis factor alpha (TNF-α) and nitrite (NO2- ) production were measured by ELISA and the Griess reaction, respectively. The compounds present in the extracts were tentatively identified by HPLC-DAD-ESI-MS/MS. RESULTS The evaluation of the biological activities showed the potential of the extracts. The activities were assigned to the presence of glycoside flavonoids mainly derived from quercetin, quinic acid derivatives, gallic acid derivatives, galloylquinic acids and proanthocyanidins. Two isomers of sinapic acid-O-hexoside were described for the first time in a Byrsonima species. CONCLUSION This research contributes to the study of the genus, it is the first report of the chemical composition of B. sericea and demonstrates the importance of the dereplication process, allowing the identification of known compounds without time-consuming procedures.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Every year between 1.2 and 5.5 million people worldwide are victims of snakebites, with about 400,000 left permanently injured. In Central America an estimated 5500 snakebite cases are reported by health centres, but this is likely to be an underestimate due to unreported cases in rural regions. The aim of this study is to review the medicinal plants used traditionally to treat snakebites in seven Central American countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama. MATERIALS AND METHODS A literature search was performed on published primary data on medicinal plants of Central America and those specifically pertaining to use against snakebites. Plant use reports for traditional snakebite remedies identified in primary sources were extracted and entered in a database, with data analysed in terms of the most frequent numbers of use reports. The scientific evidence that might support the local uses of the most frequently reported species was also examined. RESULTS A total of 260 independent plant use reports were recorded in the 34 sources included in this review, encompassing 208 species used to treat snakebite in Central America. Only nine species were reported in at least three studies: Cissampelos pareira L., Piper amalago L., Aristolochia trilobata L., Sansevieria hyacinthoides (L.) Druce, Strychnos panamensis Seem., Dorstenia contrajerva L., Scoparia dulcis L., Hamelia patens Jacq., and Simaba cedron Planch. Genera with the highest number of species used to treat snakebite were Piper, Aristolochia, Hamelia, Ipomoea, Passiflora and Peperomia. The extent of the scientific evidence available to understand any pharmacological basis for their use against snakebites varied between different plant species. CONCLUSION At least 208 plant species are traditionally used to treat snakebite in Central America but there is a lack of clinical research to evaluate their efficacy and safety. Available pharmacological data suggest different plant species may target different symptoms of snakebites, such as pain or anxiety, although more studies are needed to further evaluate the scientific basis for their use.

Abstract
Several species of Bridelia have been used in the condition of pain & arthritis in Indian folk medicine. Present study revealed the preliminary phytochemical investigation and evaluation of analgesic, anti-inflammatory and anti-arthritic activity as well as underlying mechanism of bark of Bridelia retusa Spreng. (Euphorbiaceae). The bark was subjected to extraction using pet.ether, ethyl acetate and acetone. All the extracts were significantly inhibit abdominal writhings response and licking time in late phase of formalin test. Extracts could also significantly inhibit mean paw edema of rats induced by carrageenan & histamine at dose of 200 & 400 mg/kg, i.p. Test materials also showed significant dose dependent reduction in cotton pellet granuloma & acetic acid induced vascular permeability at 400 mg/kg. Oral administration of B. retusa fractions in CFA induced arthritic rats, physical, biochemical and hematological parameters observed in arthritic animals were altered significantly to near normal condition. The maximum paw edema inhibition at day 21 was observed at 400 mg/kg. It also proved significant protection against protein denaturation & RBC membrane damage. The GC-MS analysis of EA extract revealed the presence of β-sitosterol, stigmasterol, lupeol and friedelin (Pentacyclic triterpenoid). Therefore present study has demonstrated the analgesic; anti-inflammatory and anti-arthritic activities of B. retusa bark and suggested that the molecular membrane might be associated with inhibition of biochemical and hematological parameters. Overall bioactive profile of B. retusa used phytomedicine in future for inflammatory conditions.

Abstract
CONTEXT The aerial parts of Sphagneticola trilobata (L.) Pruski (Asteraceae) are popularly used to treat topical inflammation, but have not been fully investigated. OBJECTIVE To identify polar compounds in S. trilobata extracts and develop a new topical phytomedicine based on the kaurenoic acid (KA) content while monitoring and demonstrating its topical anti-inflammatory activity. MATERIALS AND METHODS Ethanol spray-dried extract of S. trilobata was analysed by LC-MS while the KA content from semisolid was analysed by LC-UV. The extent of ear edema induced by applying 20 μL of croton oil (2.5%), arachidonic acid (AA; 2 mg/ear) and decanoylphorbol-13-acetate (TPA; 2.5 mg/ear) in mice was used to evaluate the biological activity of the semisolids, which were applied 30 min before the phlogistic agents. RESULTS Eight phenylpropanoids and four oleanane-type triterpenoid saponins were identified, majority of them reported for the first time in this species, in addition to KA. The semisolid containing 1.0% of dried extract reduced the ear edema induced by croton oil [77.2 ± 4.5%; ID50 = 0.49 (0.28-0.87%)], TPA (81.5 ± 2.4%) and AA (39.1 ± 6.9%), with decreasing effect at higher KA concentrations. This was accompanied by neutrophil migration inhibition as investigated by biochemical and histological assays. DISCUSSION AND CONCLUSION The anti-inflammatory effects were (at least in part) due to the interference in protein kinase C (PKC) activation, AA-cascade products and neutrophil migration inhibition, demonstrating the efficacy of the folk topical usage of this plant. The results support the development of a novel topical anti-inflammatory phytomedicine properly standardized to treat inflammatory dermatological diseases.

Abstract
The novel dimeric guaianolides sesquiterpene lactone Byrsoninas A and B from seed hexane extract of Byrsonima crassifolia were identified. Streptozotocin-induced mildly diabetic and severely diabetic mice were treated with these oral administrations at a dosage of 20 mg/kg of body weight per day for 30 days. Also the protective effect in vitro in RIN-5F cells against oxidative stress was investigated and TNF-α and IL-6 levels were measured. Both Byrsonina types reduced blood glucose, cholesterol, triglyceride, lipoprotein, and transaminase levels and increased HDL-cholesterol, antioxidant enzymes, and TBARS-reactive substance levels. Byrsoninas A and B both improved this glucose metabolism by reducing insulin resistance and by stimulating insulin production due to protection effect for pancreatic β-cells against oxidative stress, lipid abnormalities were reduced and, chronic inflammation responses were alleviated producing a hepatoprotective role.

Abstract
Brazilian flora biodiversity has been widely investigated to identify effective and safe phytotherapeutic compounds. Among the investigated plant species, the Byrsonima genus exhibits promising biological activities. This study aimed at evaluating the cytotoxicity of B. correifolia, B. verbascifolia, B. fagifolia and B. intermedia extracts using different assays in two cell lines (primary gastric and HepG2 cells). The different extract concentrations effects on cell viability were assayed using the MTT, aquabluer, neutral red and LDH assays. Non-cytotoxic concentrations were selected to generate cell proliferation curves and to assess cell cycle kinetics by flow cytometry. Byrsonima extracts differentially affected cell viability depending on the metabolic cellular state and the biological parameter evaluated. B. fagifolia and B. intermedia extracts exhibited lower cytotoxic effects than B. correifolia and B. verbascifolia in all assays. The results obtained with LDH and flow cytometry assays were more reliable, suggesting that they can be useful in the screening for herbal medicine and to further characterize these extracts as phytotherapeutic compounds.

Abstract
BACKGROUND Vitellaria paradoxa is a traditional medicinal plant of Cameroon. Several studies on this plant have focused on the cosmetic profile of its fruits. The present study focuses on the anti-inflammatory potency of stem barks extract of this plant. OBJECTIVE The objective was to evaluate the effect of methanolic extract of V. paradoxa (VPME) stem barks on inflammatory response in rats. MATERIALS AND METHODS Anti-inflammatory effects of VPME were evaluated in acute and chronic (28 days) inflammation induced in Wistar albino rats. The effects on hyperalgesia and locomotors activity were also quantified. The relative weight of lymphoid organs was obtained as well as some hematological parameters. RESULTS In the carrageenan-induced inflammation, VPME (75 mg/kg) exhibited a significant (66.67%) inhibition after 1 h. On the complete Freund's adjuvant-induced rheumatoid arthritis, VPME showed a significant protective effect with 8.12% inflammation against 25.00% for the control group after 2 days of the treatment. The extract (75 and 150 mg/kg) significantly reduced the score of arthritis with a maximum obtained on day 19(th) of the experimentation. There was a significant increase in the reaction time of rats on the hot plate as well as the exploratory activities of the animals in the open field. This extract significantly prevented weight, hemoglobin and red blood cells losses, and spleen hypertrophy. A protective action against skin destruction and cartilage erosion was evident. Liquid chromatography-mass spectrometry analysis of the extract revealed the presence of catechins. CONCLUSIONS These findings suggested that V. paradoxa may contribute to the reduction of the inflammatory response.

Abstract
OBJECTIVE Vitellaria paradoxa (shea tree) is used in traditional medicine for the treatment of various ailments, including, inflammation and fever. Therefore the present research investigates the anti-inflammatory and anti-rheumatic effects of V. paradoxa stem bark extracts in rats and the isolation and characterization of its active constituents. METHODS The anti-inflammatory activity of ethyl acetate extract of V. Paradoxa (VPEE) was evaluated by use of the carrageenan-induced paw oedema model in rats. Moreover, rheumatoid arthritis (RA) was induced by injection of Freund's Completed Adjuvant (FCA) into the subplantar surface of the hind paw of the male Wistar rats. Paw volume was measured plethysmometrically. Joint swelling was measured using electronic vernier caliper. Hot plate test was used to assess the effect of VPEE on hyperalgesia while open field was used to assess the locomotors activity. The relative weight of spleen, liver and thymus was obtained as well as some haematological parameters. Tibiotarsal joint was extracted for histopathology under light microscope. Chemical analysis was carried out by high resolution mass spectrometry and one and two-dimensional NMR techniques. RESULTS LC-MS analysis of the EtOAc extract revealed the presence of a new triterpenoid and several known compounds. The structure of the novel compound was elucidated by means of LC-MS and selected 1D and 2D-NMR experiments. The biological effects of ethyl acetate (VPEE), methanol (VPME) and water extracts (VPAE) of V. paradoxa were tested on carrageenan model of acute inflammation and FCA-induced rheumatoid arthritis animal model. In the carrageenan-induced inflammation, VPEE (150 mg/kg) significant (66.67%) inhibited the first (after 1h) and the second phase (4-6h) of edema formation. On the Complete Freund's adjuvant-induced rheumatoid arthritis, VPEE at the same dose showed a significantly protective effect. On days 19-28th of treatment, the maximum inflammatory percentage was between 9.60 and 8.91% for the VPEE compared to 30.91-24.29% for the controls. All the extracts significantly reduced the score of arthritis but the maximal reduction was obtained with the VPEE on day 24th of the experimentation. The altered haematological parameters in the arthritic rats were significantly recovered to near normal by the treatment with VPEE at the dose of 150 mg/kg. Further histological studies revealed the anti-arthritic activity by preventing cartilage destruction of the arthritic joints of adjuvant arthritic rats. The spleen hypertrophy induced by the FCA was also significantly inhibited. CONCLUSION These findings provide pharmacological basis for the application of the VPEE in inflammatory disorders.

Abstract
OBJECTIVES The aim of this study was to investigate the acute topical anti-inflammatory effect of the hexane fraction (HLP) of Lacistema pubescens in mice. METHODS Ear oedema models induced by croton oil, arachidonic acid, phenol, histamine, ethyl phenyl propiolate and capsaicin. Histopathological analyses of ear tissue samples sensitized with croton oil were performed. Myeloperoxidase activity (MPO), the pro-inflammatory cytokine-inhibitory effect and dermatoxicity were also evaluated. KEY FINDINGS HLP (1, 0.5 and 0.1 mg/ear) resulted in a substantial reduction in skin thickness or tissue weight on all models tested, except for capsaicin-induced ear oedema, similar to dexamethasone (0.1 mg/ear) and/or indomethacin (0.5 mg/ear). Histopathological analyses and neutrophil-mediated MPO activity confirmed the topical anti-inflammatory effect of HLP. In addition, HLP reduced IL-1β, IL-6 and tumour necrosis factor-α cytokine levels. Sitosterol-rich fraction (SRF), obtained from HLP fractionation, reduced ear oedema on croton oil and phenol models at the same dose of dexamethasone (0.1 mg/ear). No dermotoxicity was observed. CONCLUSIONS The mechanism of action of HLP was associated with the inhibition of several pro-inflammatory mediators, including cytokines, arachidonic acid metabolites and histamine, which suggested a glucocorticoid-like effect, reinforced by the presence of the steroid sitosterol. This is the first report on anti-inflammatory activity of L. pubescens leaves.

Abstract
The application of metabolomics in phytochemical analysis is an innovative strategy for targeting active compounds from a complex plant extract. Species of the Asteraceae family are well-known to exhibit potent anti-inflammatory (AI) activity. Dual inhibition of the enzymes COX-1 and 5-LOX is essential for the treatment of several inflammatory diseases, but there is not much investigation reported in the literature for natural products. In this study, 57 leaf extracts (EtOH-H2O 7:3, v/v) from different genera and species of the Asteraceae family were tested against COX-1 and 5-LOX while HPLC-ESI-HRMS analysis of the extracts indicated high diversity in their chemical compositions. Using O2PLS-DA (R2 > 0.92; VIP > 1 and positive Y-correlation values), dual inhibition potential of low-abundance metabolites was determined. The O2PLS-DA results exhibited good validation values (cross-validation = Q2 > 0.7 and external validation = P2 > 0.6) with 0% of false positive predictions. The metabolomic approach determined biomarkers for the required biological activity and detected active compounds in the extracts displaying unique mechanisms of action. In addition, the PCA data also gave insights on the chemotaxonomy of the family Asteraceae across its diverse range of genera and tribes.

Abstract
Background Inflammation and pain underlies several pathological conditions. Synthetic drugs used for the management of these conditions carry severe toxic effects. Globally efforts are ongoing to introduce novel medicinal plants to develop effective, economic and innocuous drugs. The current study was aimed at investigating the antipyretic, anti-inflammatory and analgesic activity of methanol extract of A. hydaspica aerial parts (AHM) and its active fraction. Furthermore identification and isolation of polyphenolic compounds was carried out to identify the active principles. Methods Yeast induced pyrexia, Paw edema, acetic acid-induced writhing and hot plate test were carried out in vivo. HPLC-DAD analysis and combination of different chromatographic techniques, involving vacuum liquid chromatography (VLC) and flash chromatography (FC) were carried out for chemical characterization. The structural heterogeneity of flavanols was characterized by ESI- MS, 1H NMR, 13C NMR and 2D NMR spectroscopic analyses, and also by comparison with reported literature. Results Oral administration of A. hydaspica methanol extract (AHM) and A. hydaspica ethyl acetate fraction (AHE), showed dose and time dependent decrease in body temperature in yeast induced pyrexia, comparable to standard, Paracetamol. AHM and AHE (150 mg/kg) significantly (p < 0.001) inhibit pain sensation in various pain models, i.e. acetic acid induced writhing and hot plate test. Similarly AHM and AHE demonstrated an anti-inflammatory effect in carrageenan-induced paw edema in rats and 150 mg/kg dose being distinctly more effective (91.92% inhibition). When studied on prostaglandin E2 (PGE2) induced edema in rats, AHM and AHE showed maximum inhibition of edema at 150 mg/kg after 4 h. HPLC chromatogram of AHM revealed the presence of gallic acid, catechin, rutin and caffeic acid. Chromatographic separation and structure characterization of AHE, has led to the identification of three flavan-3-ol derivative including 7-O-galloyl catechin, +catechin and methyl gallate, which have been reported for the first time in A. hydaspica. Conclusion These results revealed that the presence of bioactive compounds in A. hydaspica might be responsible for the pharmacological activities, confirming the indigenous utility of A. hydaspica against inflammatory disorders.

Abstract
A hydrophilic extract of murici (Byrsonima crassifolia), a fruit native to the North and Northeast regions of Brazil, was evaluated in relation to its phenolic composition and in vitro antioxidant potential against some physiologically relevant reactive oxygen and nitrogen species. Additionally, the protective effect of murici extract against peroxyl radical (ROO)-induced toxicity to human erythrocytes was also determined. The major phenolic compound, determined by HPLC-DAD-MSn, was quercetin (2.72±0.35μg/mL). The extract was able to scavenge ROO (0.30±0.04μmoltroloxequivalent/mg), hypochlorous acid (IC50=10.0±0.1μg/mL), hydroxyl radical (IC50=7±1μg/mL) and peroxynitrite anion (IC50=21.0±0.6μg/mL and 17.0±1.6μg/mL, respectively, in absence and presence of NaHCO3). Human erythrocytes were subjected to oxidative damage, but murici extract was not able to inhibit hemolysis, even at the highest tested concentration. On the other hand, the extract inhibited hemoglobin oxidation (IC50=271±44μg/mL), lipid peroxidation (1000μg/mL) by 48±5%, depletion of glutathione (100μg/mL) by 49±2% and formation of its oxidized form (100μg/mL) by 96±4%.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In Dominica, women offer dysmenorrhea, delayed menses, and menorrhagia as prevalent menstrual troubles. Dominican humoral theory considers menstruation to be "hot" such that menstrual problems are caused by the introduction of too much "cold" in the body. These conditions can be painful and may require herbal medicine. Our method finds the most culturally salient plants for these conditions-those which are of common knowledge across the population. We hypothesize that cultural agreement on ethnobotanical treatments (1) reflects their perceived ethnophysiological efficacy, and that (2) salient plants contain bioactive compounds appropriate for the menstrual conditions for which Dominicans employ the plants. MATERIALS AND METHODS Qualitative data on local explanatory models and treatment of menstrual conditions were collected using participant-observation, focus groups, and informal key informant interviews. Quantitative ethnobotanical data come from freelist (or "free-list") tasks, conducted with 54 adults. RESULTS Mean salience values calculated from freelisted data reveal that the same four plants, Cinnamomum verum (synonym Cinnamomum zeylanicum) (Lauraceae), Mentha suaveolens (Lamiaceae), Pimenta racemosa (Myrtaceae) and Sphagneticola trilobata (synonym Wedelia trilobata) (Asteraceae) are used to treat dysmenorrhea and delayed menses. The only remedy reported for menorrhagia, Sphagneticola trilobata (Asteraceae), is also a treatment for dysmenorrhea and delayed menses. The Dominican humoral system views menstruation as a "hot" condition, yet these "bush medicines" are also "hot." Dominicans do not view menstruation as a problem, rather, they reckon that excess "cold" in a woman׳s menstruating body impedes menstrual function to cause problems thus requiring "hot" plants to alleviate their symptoms. A literature review revealed that all four plants contain analgesic, anti-nociceptive, and anti-inflammatory properties. Additionally, Mentha suaveolens is muscle-relaxing and anti-spasmodic, Cinnamomum verum has a mild anti-coagulant, and Sphagneticola trilobata has wound healing, anti-stress, and sedative properties. CONCLUSIONS In Dominican menstrual problems there is correspondence between cultural consensus, bioactivity, and humoral theory. Examining the ethnophysiology of menstruation and its complications provides evidence for the expectations of actions and effectiveness of locally culturally salient medicinal plants.

Abstract
BACKGROUND In Mexican traditional medicine, the seeds of Byrsonima crassifolia have been used in the treatment of diabetes, rheumatism and for wound healing. The aim was to evaluate the effect of seeds of B. crassifolia on insulin release from the pancreatic beta cells in streptozotocininduced diabetic rats. MATERIALS AND METHODS In the present study, we evaluated the beneficial effect of seeds B. crassifolia streptozotocin-induced type 1 diabetic rats. Insulin level; insulin sensitivity index, insulin content in pancreas, malonaldehyde, nitric oxide contents, oxidative stress parameters were assayed. Serum glucose levels were determined by the glucose oxidase method. To determine the insulin releasing activity, after extract treatment, the pancreas was excised. Pancreatic sections were processed for examination of insulin-releasing activity using an imunocytochemistry kit. RESULTS Administration of the hexane extract (200 and 400 mg/kg), exhibited a significant reduction in serum glucose. Administration of streptozotocin decreased the number of beta cells with insulin secretory activity in comparison with intact rats; but treatment with the B. crassifolia seed extract increased significantly the activity of the beta cells in comparison with the diabetic control rats. The extract decreased serum glucose in streptozotocin-induced diabetic rats and increased insulin release from the beta cells of the pancreas. CONCLUSION These finding suggest that B. crassifolia seed has beneficial effect for diabetes through decreasing blood glucose and lipid levels, increasing insulin sensitivity index and insulin content, up-regulating antioxidant enzyme activity and decreasing lipid peroxidation.

Abstract
OBJETIVE To study the effect of seeds of Byrsonima crassifolia in diabetic wound healing. METHODS Wound healing potential of hexane extract in the form of simple ointment for the treatment of dermal wounds was studied in streptozotocin-induced diabetic rats on excision wound, incision wound and dead space wound. Various parameters such as epithelization period, scar area, tensile strength, hydroxyproline, total protein, DNA, hexosamine, uronic acid, antioxidant enzymes including superoxide dismutase (SOD) and catalase activity (CAT) were used to evaluate the effect of B. crassifolia on wound healing. RESULTS Hexane extract in form topical accelerates the wound healing process by decreasing the surface area of the wound with a significant increase in the rate of wound contraction and tensile strength; increase granulation tissue dry weight, hydroxyproline, total protein, DNA and SOD and CAT when compared with diabetic control. CONCLUSION B. crassifolia was effective in promoting diabetic wound healing in rats through the processes of tissue regeneration.

Abstract
The traditional use of Murraya koenigii as Asian folk medicine prompted us to investigate its wound healing ability. Three carbazole alkaloids (mahanine (1), mahanimbicine (2), mahanimbine (3)), essential oil and ethanol extract of Murraya koenigii were investigated for their efficacy in healing subcutaneous wounds. Topical application of the three alkaloids, essential oil and crude extract on 8 mm wounds created on the dorsal skin of rats was monitored for 18 days. Wound contraction rate and epithelialization duration were calculated, while wound granulation and collagen deposition were evaluated via histological method. Wound contraction rates were obvious by day 4 for the group treated with extract (19.25%) and the group treated with mahanimbicine (2) (12.60%), while complete epithelialization was achieved on day 18 for all treatment groups. Wounds treated with mahanimbicine (2) (88.54%) and extract of M. koenigii (91.78%) showed the highest rate of collagen deposition with well-organized collagen bands, formation of fibroblasts, hair follicle buds and with reduced inflammatory cells compared to wounds treated with mahanine (1), mahanimbine (3) and essential oil. The study revealed the potential of mahanimbicine (2) and crude extract of M. koenigii in facilitation and acceleration of wound healing.

Abstract
Kaurenoic acid [ent-kaur-16-en-19-oic acid (1)] is a diterpene present in several plants including Sphagneticola trilobata. The only documented evidence for its antinociceptive effect is that it inhibits the writhing response induced by acetic acid in mice. Therefore, the analgesic effect of 1 in different models of pain and its mechanisms in mice were investigated further. Intraperitoneal and oral treatment with 1 dose-dependently inhibited inflammatory nociception induced by acetic acid. Oral treatment with 1 also inhibited overt nociception-like behavior induced by phenyl-p-benzoquinone, complete Freund's adjuvant (CFA), and both phases of the formalin test. Compound 1 also inhibited acute carrageenin- and PGE(2)-induced and chronic CFA-induced inflammatory mechanical hyperalgesia. Mechanistically, 1 inhibited the production of the hyperalgesic cytokines TNF-α and IL-1β. Furthermore, the analgesic effect of 1 was inhibited by l-NAME, ODQ, KT5823, and glybenclamide treatment, demonstrating that such activity also depends on activation of the NO-cyclic GMP-protein kinase G-ATP-sensitive potassium channel signaling pathway, respectively. These results demonstrate that 1 exhibits an analgesic effect in a consistent manner and that its mechanisms involve the inhibition of cytokine production and activation of the NO-cyclic GMP-protein kinase G-ATP-sensitive potassium channel signaling pathway.

Abstract
Byrsonima crassifolia (Malpighiaceae) has been used in traditional medicine for the treatment of some mental-related diseases; however, its specific neuropharmacological activities remain to be defined. The present study evaluates the anxiolytic, anticonvulsant, antidepressant, sedative effects produced by the extracts of Byrsonima crassifolia, and their influence on motor activity in ICR mice. Additionally, we determine the acute toxicity profiles of the Byrsonima crassifolia extracts and the presence of neuroactive constituents. Our results show that the methanolic extract of Byrsonima crassifolia produces a significant (P<0.05) antidepressant effect in the forced swimming test in mice at 500 mg/kg dose. However, it does not possess anxiolytic, sedative, or anticonvulsant properties, and does not cause a reduction of mice locomotion (P>0.05). Although the main compound of the methanolic extract was identified as quercetin 3-O-xyloside (12 mg/kg), our findings suggest that flavonoids, such as rutin (4.4 mg/kg), quercetin (1.4 mg/kg) and hesperidin (0.7 mg/kg), may be involved in the antidepressant effects. To the best of our knowledge, the present study constitutes the first report on the presence of the flavonoids with neuropharmacological activity rutin and hesperidin in Byrsonima crassifolia. In conclusion, the present results showed that the methanolic extract standardized on flavonoids content of Byrsonima crassifolia possesses potential antidepressant-like effects in the FST in mice, and could be considered as relatively safe toxicologically with no deaths of mice when orally administered at 2000 mg/kg.

Abstract
An extract of bark from the tropical rainforest plant Byrsonima crassifolia was screened for inhibition of diubiquitin formation by the human ubiquitin-conjugating enzyme E2-25K. Activity assays with both the full-length enzyme and a truncated, active catalytic UBC domain revealed that the extract contained inhibitory properties. Separation of the extract into individual components and additional screens identified vitexin as the active inhibitor. An IC50 for vitexin was calculated to be approximately 0.5 mM. Molecular modeling simulations were used to predict the mode of inhibition and NMR spectra were used to confirm the binding site of vitexin to E2-25K.

Abstract
AIM OF THE STUDY Caryocar coriaceum Wittm. fruit pulp fixed oil (CCFO) has been widely employed by communities from Brazil Northeastern in the treatment of skin inflammation, respiratory affections, wound healing and muscle pain. In this study, we evaluated the topical effect of CCFO against different irritant agents in vivo, in order to verify its antiedematous effect as well to unravel its tentative mechanisms of action. MATERIALS AND METHODS CCFO was obtained from Caryocar coriaceum fruits using ethyl acetate as solvent. Ear edema provoked by the application of Croton oil (single and multiple applications), arachidonic acid (AA), capsaicin, phenol and histamine to Swiss mice was used to evaluate the topical anti-inflammatory effect of CCFO. Histological analysis from mice ears sensitized with Croton oil and AA single application was also performed. RESULTS Crude CCFO (20μL/ear) demonstrated significant topical antiedematous effect against Croton oil single (inhibition of 32.0%; P<0.05) and multiple (41.4% after 9 days, P<0.001) applications, AA (inhibition of 49.7%; P<0.01) and phenol (inhibition of 38.8%; P<0.001). In contrast, CCFO did not antagonize the edema caused by topical treatment with capsaicin and histamine when compared to control group (P>0.05). Histological analysis also revealed that CCFO was able to reduce the edema and the influx of inflammatory cells in mice ears sensitized with Croton oil and AA. CONCLUSIONS CCFO exhibited a similar profile of topical anti-inflammatory activity to that of drugs that classically modulate the production of arachidonic acid metabolites. The study also indicates the potential application of CCFO as an important herbal medicine to be used against skin inflammatory diseases.

Abstract
AIM OF THE STUDY Trichosanthes cucumerina Linn. (Family: Cucurbitaceae) is one of the medicinal plants that is often used in Sri Lankan traditional systems of medicine. One of its uses is the treatment of inflammatory conditions. However, validity of the anti-inflammatory activity has not been scientifically investigated so far. Therefore, the aim of this study was to investigate the anti-inflammatory potential of Trichosanthes cucumerina hot water extract (HWE) and its fractions. MATERIALS AND METHODS The anti-inflammatory activity of Trichosanthes cucumerina was evaluated by use of the carrageenan-induced paw oedema model in Wistar rats. In addition, the mechanism/s by which Trichosanthes cucumerina is mediated the anti-inflammatory activity was assessed by determining its effects on (a) membrane stabilizing activity and (b) nitric oxide inhibitory activity. RESULTS Apart from the lowest dose of the HWE, other tested doses (500, 750, 1000 mg/kg) produced a significant (P ≤ 0.05) inhibition of the inflammation, most pronounced at 5h after the injection of carrageenan. The anti-inflammatory effect induced by 750 mg/kg, was comparable to that of the reference drug, indomethacin at 4 and 5h. Inhibition of nitric oxide (NO) production and membrane stabilization activities are probable mechanisms by which Trichosanthes cucumerina mediates its anti-inflammatory actions. Among the tested fractions, methanol fraction (MEF) and aqueous fraction (AQF) at a dose of 75 mg/kg exhibited marked inhibition against carrageenan-induced hind paw oedema. The anti-inflammatory effect induced by MEF, was comparable to that of the reference drug, indomethacin and as well as to the 750 mg/kg of HWE at 4 and 5h. CONCLUSIONS (a) These findings rationalize the traditional usage of this plant as an anti-inflammatory agent and (b) membrane stabilizing properties and NO inhibitory activity are possible mechanisms through which Trichosanthes cucumerina mediates its anti-inflammatory action.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ancient tribes in the Western Ghats of India use the roots of Decalepis hamiltonii Wight and Arn (Asclepiadaceae) for several medicinal purposes particularly inflammation. AIM To investigate whether the pure compounds obtained from the Decalepis hamiltonii have anti inflammatory activity. MATERIALS AND METHODS The bioactive lead molecules from the roots of Decalepis hamiltonii were extracted into dichloromethane/methanol and purified by silica gel column chromatography. Structural elucidation of the purified compounds was performed with (1)H and (13)C NMR and mass spectrometry. The in vitro anti inflammatory activity of the pure compounds was studied in mitogen induced peripheral blood mononuclear cells (PBMCs) employing [(3)H] thymidine uptake assay and their effect on cytokine expression by reverse transcriptase polymerase chain reaction (RT-PCR). The inhibition of nuclear factor kappaB (NF-kappaB) activity in the presence of pure compounds was determined in J774 A.1 cells. The cytotoxicity of the compounds was tested using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay kit. RESULTS AND DISCUSSION Lupeol acetate (Compound 1) and (2S)-5,7,4'-trihydroxy flavanone 4'-O-beta-d-glucoside (Compound 2) isolated from Decalepis hamiltonii roots inhibited the proliferation of mitogen induced PBMCs with an IC(50) value of 8 and 0.5mug/ml respectively. MTT assay revealed the compounds to be non-cytotoxic. Though, both the compounds down regulated the synthesis of mRNA of the pro inflammatory cytokines, interleukin-2 (IL-2) and tumour necrosis factor-alpha (TNF-alpha), the anti inflammatory cytokine interleukin-10 (IL-10), was found to be up regulated. NF-kappaB activation in J774 A.1 cells were also inhibited by both the compounds. CONCLUSION Lupeol acetate and (2S)-5,7,4'-trihydroxy flavanone 4'-O-beta-d-glucoside isolated from Decalepis hamiltonii roots showed anti inflammatory activities by down regulating TNF-alpha and IL-2 specific mRNA, besides up regulating the synthesis of mRNA of IL-10.
