Anti-Inflammatory, Anti-Osteoclastogenic and Antioxidant Effects of Malva sylvestris Extract and Fractions: In Vitro and In Vivo Studies

Bioassay-Guided Assessment of Antioxidative, Anti-Inflammatory and Antimicrobial Activities of Extracts from Medicinal Plants via High-Performance Thin-Layer Chromatography

Natural products and their analogues have contributed significantly to treatment options, especially for anti-inflammatory and infectious diseases. Thus, the primary objective of this work was to compare the bioactivity profiles of selected medicinal plants that are historically used in folk medicine to treat inflammation and infections in the body. Chemical HPTLC fingerprinting was used to assess antioxidant, phenolic and flavonoid content, while bioassay-guided HPTLC was used to detect compounds with the highest antibacterial and anti-inflammatory activities. The results of this study showed that green tea leaf, walnut leaf, St. John's wort herb, wild thyme herb, European goldenrod herb, chamomile flower, and immortelle flower extracts were strong radical scavengers. Green tea and nettle extracts were the most active extracts against E. coli, while calendula flower extract showed significant potency against S. aureus. Furthermore, green tea, greater celandine, and fumitory extracts exhibited pronounced potential in suppressing COX-1 activity. The bioactive compounds from the green tea extract, as the most bioactive, were isolated by preparative thin-layer chromatography and characterized with their FTIR spectra. Although earlier studies have related green tea's anti-inflammatory properties to the presence of catechins, particularly epigallocatechin-3-gallate, the FTIR spectrum of the compound from the most intense bioactive zone showed the strongest anti-inflammatory activity can be attributed to amino acids and heterocyclic compounds. As expected, antibacterial activity in extracts was related to fatty acids and monoglycerides.

Development and characterization of a new active and intelligent packaging system based on soluble soybean polysaccharide-Malva sylvestris extract

This work aimed to develop an active and intelligent film based on soluble soybean polysaccharide (SSPS)/Malva sylvestris extract (MSE) to extend the shelf life of foodstuff and detect indirectly the food spoilage. The influence of MSE content on physico-mechanical properties, biological activity, and pH sensitivity of the SSPS-based films was examined. When the MSE concentration increased from 0 to 6% (w/w), water solubility and water vapor permeability of the films decreased (p ˂ 0.05). Clear antioxidant and antibacterial capacities were observed for SSPS films incorporated with different concentrations of MSE. SSPS/MSE films could sense the pH variation in a pH range of 7 to 8. SSPS/MSE film was used to detect the spoilage of shrimp and showed a pH-sensitive highly distinctive color variation from grey to dark green as the shrimp's quality altered. Overall, SSPS/MSE film can be introduced as a promising candidate for application as active and intelligent packaging.

A comprehensive review on medicinal plants possessing antioxidant potential

Many research studies have proposed that about two-thirds of the medicinal plant species of the world possess significant antioxidant potential. Antioxidants are very beneficial as they decrease oxidative stress (OS) in cells and hence play their role in management as well as treatment of numerous diseases like cancers, cardiovascular diseases, as well as many inflammatory illnesses. This review comprises the antioxidant potential of numerous parts of medicinal plants like leaves, stems, roots, seeds, fruits, as well as bark. Synthetic antioxidants named butylated hydroxyanisole (BHA) as well as butylated hydroxytoluene (BHT) are extensively employed in foods because of their role as food preservatives. Several natural antioxidants have better efficacy as compared to synthetic antioxidants. These medicinal plants include Geranium sanguineum L., Rheum ribes L., Diospyros abyssinica, Sargentodoxa cuneata Rehd. Et Wils, Pistacia lentiscus, Ficus microcarpa L. fil., Polyalthia cerasoides (Roxb.) Bedd, Cunn, Teucrium polium L., Crataeva nurvala Buch-Ham., Urtica dioica L., Dracocephalum moldavica L., Momordica Charantia L., Acacia auriculiformis A., Bidens pilosa Linn. The Lamiaceae species, Radiata, Leea indica, Pelargonium endlicherianum, Salvia officinalis L., and Uncaria tomentosa (Willd.) DC. The literature study disclosed more side effects of synthetic antioxidants (including food additives) in comparison with natural antioxidants and for prevention of many diseases.

Modification of Mediterranean Diet Pyramid from an Island’s perspective

ABSTRACT Objective The present study aimed to determine traditional and local food consumption and adherence to the Mediterranean diet in Cyprus. And also, aimed to improve their adherence to the Mediterranean diet and traditional and local food consumption. From this point, this current study aimed to revise the Cyprus Mediterranean Diet Pyramid, based on the Current Mediterranean Diet Pyramid. Methods The sample size was calculated as a minimum of 386 according to a 95.0% confidence interval, and a 5.0% error. This study was conducted online between November 2020-April 2021 in Cyprus. All volunteers were invited to this study on the national public internet platforms. Participant´s adherence to the Mediterranean diet was determined by the Mediterranean Diet Adherence Screener. Traditional and local food consumption frequencies were determined by a Food Frequency Questionnaire. A novel Cyprus Mediterranean Diet Pyramid was developed with traditional and local food items for Cyprus. The modification was also aimed to safeguard planet health, to increase traditional food consumption and adherence to the Mediterranean diet. Results 1,007 adults (78.0% native islanders/Cypriots) participated voluntarily in the current study. The mean Mediterranean Diet Adherence Screener score was 7.55±2.30 points and only 34.4% had high adherence to the Mediterranean diet. According to their responses, there was a need to increase use of olive oil, vegetables, fruits, fish, and red wine consumption and to decrease red meat and dessert consumption. According to responses to the Mediterranean Diet Adherence Screener and their traditional/local food consumption frequencies an up-to-date Cyprus Mediterranean Diet Pyramid was done hence a national food pyramid for Cyprus. Commonly consumed traditional and local foods were added to the pyramid to facilitate increased adaptation of the Mediterranean diet in the general population. Adequately consumed foods were added to make it more region-specific and rarely consumed foods were added to help to increase consumption. Conclusion This modification is believed to be instrumental to increase Mediterranean diet adaptation, traditional/local food consumption and decrease the impact of nutrition on the planet´s health. And also, this modification can shed light on the development of the other traditional food pyramids.

Management of "stone pain" between the 18th and 19th centuries: A brief history of a medical prescription in the Viceroyalty of New Granada

INTRODUCTION

The presence of stones in the urinary tract is a condition that has accompanied humans since ancient times. In colonial times, this condition was known as "stone pain" and its non-surgical management was based on the use of medicines derived from plants, animals and minerals.

OBJECTIVE

To contextualize a medical prescription used to modulate stone pain in the 18th century in the New Kingdom of Granada. Additionally, to analyze its components and evaluate the basis of its possible phytotherapeutic effects on the disease and pain.

MATERIAL AND METHOD

Document search in the Cipriano Rodríguez Santamaría Historical Archive of the Octavio Arizmendi Posada Library at Universidad de La Sabana. The document entitled "Prescription for bladder or kidney stone pain" was analyzed, and a complementary review of current scientific literature and original texts was performed with no time limits, in order to compare this prescription to related findings in the history of medicine.

RESULTS

The transcription of the source document revealed several phytotherapeutic agents such as chamomile (Matricaria recutita), lilies (Lilium lancifolium), clover (Trifolium pratense), and mallow roots (Malva sylvestris), accompanied by a large amounts of water.

CONCLUSIONS

There is scientific evidence that could explain the anti-inflammatory and antioxidant effects of all plant-derived medicines used in this prescription. Abundant water intake to increase urine volume was an essential part of treatment. However, the lack of more precise data related to the prescription and the evolution of the patients makes it difficult to analyze its therapeutic efficacy.

Analgesic and anti-inflammatory properties of hydroalcoholic extracts of Malva sylvestris, Carum carvi or Medicago sativa, and their combination in a rat model

OBJECTIVE

The aim of this study was to evaluate the analgesic and anti-inflammatory effects of the hydroalcoholic extracts of Malva sylvestris flowers or Carum carvi and Medicago sativa seeds, alone and in combination, which have been used in traditional Iranian medicine.

METHODS

Male Wistar rats were divided into 6 treatment groups: distilled water, sodium salicylate (SS), M. sylvestris extract (600 mg/kg), C. carvi extract (600 mg/kg), M. sativa extract (300 mg/kg) and combined extract (including 300 mg/kg M. sylvestris and C. carvi extracts, and 150 mg/kg M. sativa extract). The formalin pain model was used to evaluate the antinociceptive effects of the treatments. For anti-inflammatory effect, acute (one hour after injection) and chronic (during a week after injection) paw inflammation was measured after subcutaneous injection of 2.5% formalin in the hindpaw. Finally, tissue samples from all groups were prepared for histopathological studies.

RESULTS

The combined extract significantly inhibited the nociception in the acute phase of the formalin test (P < 0.001). In the chronic phase, all the extracts and SS had significant analgesic effect (P < 0.001). Analgesic activity of the combined extract was significantly stronger than SS (P < 0.01). In the acute inflammation model, M. sylvestris, C. carvi and the combined drug had significant inhibitory effects against paw edema (P < 0.05). All extracts, individually and in combination, significantly alleviated chronic paw inflammation (P < 0.01). The combined extract had much more anti-inflammatory activity than SS (P < 0.05). Histopathological results indicated improvement and reduction of inflammatory factors in the treatment groups.

CONCLUSION

M. sylvestris, C. carvi and M. sativa have analgesic and anti-inflammatory properties. Potentially, each of these extracts or a mixture of them might be a valuable alternative drug to control pain and inflammation.

In vitro anti-inflammatory properties of Smilax campestris aqueous extract in human macrophages, and characterization of its flavonoid profile

ETHNOPHARMACOLOGICAL RELEVANCE

Extracts of Smilax campestris Griseb (Smilacaceae) have been employed in the treatment of several inflammatory diseases as a traditional herbal medicine. However, the cellular and molecular mechanisms involved in the observed effects remain elusive. Macrophages are known to play a central role in inflammatory responses. These cells are activated in response to a diversity of danger signals and produce several mediators of inflammation that eventually regulate the immune response. For all the above mentioned, scientific evidence is required to support the popular use of S. campestris.

AIM OF THE STUDY

We aimed to investigate the anti-inflammatory effect of S. campestris aqueous extract (SME) in activated THP-1 human macrophages, on the production of some mediators of inflammation and oxidative stress in order to provide scientific support for its popular use.

MATERIALS AND METHODS

The characterization of SME was assessed by HPLC-MS/MS. The production of the pro-inflammatory cytokines and chemokines was evaluated by ELISA. The activity of metalloproteases was evaluated by zymography. The subcellular localization of the NF-κB transcription factor was analysed by Western blot. The superoxide anion and glutathione levels were assessed by flow cytometry. The cytotoxicity induced by SME in THP-1 macrophages was also investigated by the LDH release test.

RESULTS

In the present study, we have identified catechin and glycosylated derivatives of quercetin (quercetin-3-O-glucoside, quercetin-3-O-galactoside, rutin and quercetin-3-rhamnoside) as major components of the aqueous SME. We found that SME significantly decreased the production of the pro-inflammatory cytokines tumour necrosis factor (TNF)- α, interleukin (IL)-1β, IL-6, IL-8 and monocyte chemoattractant protein (MCP)-1 and the activity of the metalloproteinase (MMP)-9, in lipopolysaccharide-activated macrophages derived from the monocytic cell line THP-1. Furthermore, SME diminished the expression of NF-κB p65 subunit in the nuclear fraction. In addition, SME decreased the production of superoxide anion in THP-1 macrophages, without altering the levels of reduced glutathione.

CONCLUSION

These results suggest that SME exerts its anti-inflammatory effects in human activated macrophages by inhibiting the production of pro-inflammatory cytokines, matrix metalloproteinases and the NF-κB transcription factor pathway along with a reduction of oxidative stress mediators. Moreover, catechin and glycosylated derivatives of were identified by HPLC-MS/MS in SME. Our findings provide scientific support for the traditional use of the S. campestris extracts.

Malva species: Insights on its chemical composition towards pharmacological applications

Malvaceae family is typical from the Mediterranean region, contains 240 genera and more than 4,200 species. They are most commonly used as ornamental plants, although they can also be conceived as a food resource and remedy for various diseases, such as digestive, respiratory, genitourinary, throat infections, and skeletal and skin disorders, as also injuries where they are profoundly applied for skin care and as antiseptic and demulcent. They also possess diuretic, lenitive, spasmolytic, and laxative effects, besides to be used as antidiarrheal. Thus, the present review provides in-depth data on Malva spp. potential applications and phytochemical composition for food and pharmaceutical industries. Habitat and cultivation conditions and the clinical reports related to its biological effects are also emphasized. Malva spp. possess a wide variety of chemical constituents (such as polysaccharides, coumarins, flavonoids, polyphenols, vitamins, terpenes, and tannins) found in different plant organs, especially in leaves and flowers, connected to their biological activity. In general, Malva spp. have rather moderate antimicrobial activity, high antiinflammatory and wound healing activities, strong antioxidant activity, and anticancer properties. Results from in vitro and in vivo experiments encourage more in-depth studies, namely clinical trials, towards to improve knowledge on the use of Malva spp. for the treatment of various health conditions in humans.

Malva sylvestris extract alleviates the astrogliosis and inflammatory stress in LPS-induced depression mice

Neuro-inflammation is widely regarded as the inflammation occurred in the central nervous system (CNS) tissue, which authentically involved in the pathogenesis such as depression although the underlying mechanism remains to be elucidated. Malva sylvestris (MS), a plant widely used in traditional medicine to mitigate urological, respiratory and oral diseases, exhibits excellent anti-oxidative and anti-inflammatory properties. In the present study, we first used LPS-induced depression-like mice to evaluate the neuro-protective effect of MS extract. We found that, after 7 days' administration of MS extract, the cognitive impairment of LPS-induced depression-like mice was efficiently alleviated, evaluated by behavioral test including the Open field, Morris water maze (MWM), Elevated plus-maze (EPM) and Rota-rod test. Furthermore, we found that MS extract also inhibited the LPS-induced neuron apoptosis and astrogliosis both in the cortex and the CA1 region of hippocampus. Finally, our findings showed that the extract of MS relieved inflammatory stress induced by LPS injury, indicated by the down-regulation of IL-1β/6 and TNF-α, and up-regulation of IL-4 level both in vitro and in vivo. Collectively, MS extract exhibits neuro-protective activity in vivo, and therefore, it may be widely used for food to relieve the symptoms of neuro-inflammation associated disorders such as depression.

Malva sylvestris derivatives as inhibitors of HIV-1 BaL infection

The emphasis of the present study is to evaluate a natural product and the potential microbicide activity using a dual chamber infection method. Malva sylvestris extracts and fractions were screened for anti-HIV activity by measuring the virus-antibody neutralization. Plant extracts with strong antiviral activity working in nanomolar or picomolar range can be used to enhance the activity of synthetic compounds and work as anti-HIV agents. The aqueous fraction (AF) of M. sylvestris demonstrated antiviral activity in a model with epithelial and blood cell lines. The AF showed an effective antiviral potential on the TZM-bl cells with reduction scores higher than 60% of infectivity. Quantification of p24 in the supernatant of the co-culture model demonstrated a reduction in the number of viral particles after AF treatment (p < 0.05). Cytokines were quantified and all signaling inflammatory markers; IL1-alpha, IL-beta, IL-6, IL-8 and GM-CSF (p < 0.05) were modulated by positive control and AF treatments. In particular, IL-6 had lower levels of expression in Malva groups when compared to the Zidovudine positive control group. Natural occurring derivatives of M. sylvestris demonstrated to work inhibiting reverse transcriptase enzyme action. M. sylvestris contains highly potential anti-HIV-1 BaL components and may be considered a potential source for new formulations in the development of topical microbicides.

Protective effect of Malva sylvestris L. extract in ischemia-reperfusion induced acute kidney and remote liver injury

Mallow (Malva sylvestris L.) has had medicinal and therapeutic uses in addition to its oral consumption. The present study was conducted to examine the protective effect of Malva sylvestris L. extract on ischemia-reperfusion-induced kidney injury and remote organ injuries in the liver. Before ischemia-reperfusion, rats in the different groups received intraperitoneal normal saline or mallow extract at the doses of 200, 400 or 600 mg/kg of body weight. After 30-minutes of bilateral renal ischemia followed by 24-hours of reperfusion, tissue damage in the kidney and liver samples were determined through studying H&E-stained slides under a light microscope. The degree of leukocyte infiltration and tissue mRNA expressions of TNF- and ICAM-1 were then measured to examine the degree of renal inflammation. The renal tissue MDA and FRAP levels were measured for determining the amount of oxidative stress. Plasma concentrations of creatinine, urea, ALT and ALP were also measured. Ischemia-reperfusion led to a significant increase in plasma concentrations of creatinine, urea, ALT and ALP, and renal tissue MDA, and a significant decrease in renal tissue FRAP. The expression of pro-inflammatory factors in the kidney tissue, the level of leukocyte infiltration and the amount of tissue damage in the kidney and liver also increased. Pretreatment by mallow extract led to a significant improvement in all the variables measured. The 200- and 400-mg doses yielded better results in most parameters compared to the 600-mg dose. The findings showed that mallow extract protects the kidney against ischemia-reperfusion and reduces remote organ injury in the liver.

Anti-Inflammatory Effect of Malva sylvestris, Sida cordifolia, and Pelargonium graveolens Is Related to Inhibition of Prostanoid Production

The ability of plant extracts and preparations to reduce inflammation has been proven by different means in experimental models. Since inflammation enhances the release of specific mediators, inhibition of their production can be used to investigate the anti-inflammatory effect of plants widely used in folk medicine for this purpose. The study was performed for leaves and flowers of Malva sylvestris, and leaves of Sida cordifolia and Pelargonium graveolens. These are three plant species known in Brazil as Malva. The anti-inflammatory activity of extracts and fractions (hexane, chloroform, ethyl acetate, and residual) was evaluated by quantitation of prostaglandins (PG) PGE₂, PGD₂, PGF2α, and thromboxane B₂ (the stable nonenzymatic product of TXA₂) concentration in the supernatant of lipopolysaccharide (LPS)- induced RAW 264.7 cells. Inhibition of anti-inflammatory mediator release was observed for plants mainly in the crude extract, ethyl acetate fraction, and residual fraction. The results suggest superior activity of S. cordifolia, leading to significantly lower values of all mediators after treatment with its residual fraction, even at the lower concentration tested (10 μg/mL). M. sylvestris and P. graveolens showed similar results, such as the reduction of all mediators after treatment, with leaf crude extracts (50 μg/mL). These results suggest that the three species known as Malva have anti-inflammatory properties, S. cordifolia being the most potent.

tBHQ Suppresses Osteoclastic Resorption in Xenogeneic-Treated Dentin Matrix-Based Scaffolds

Extracellularmatrix (ECM)-based scaffolds are important for their potential therapeutic application. Treated dentin matrix (TDM), a kind of ECM, seeded with allogeneic dental follicle stem cells (TDM/aDFC) provides a suitable inductive microenvironment for tooth root regeneration. Considering the limited sources, xenogeneic TDM (xTDM) is a possible alternative to allogeneic TDM; however, xTDM-based scaffold presents severe osteolysis and resorption lacunae causing regenerated tooth root failure. Immune response-induced excessive osteoclastogenesis plays a critical role in xenogeneic scaffold osteolysis and resorption. The impact of antioxidant, tert-butylhydroquinone (tBHQ), on xTDM/aDFCs-induced osteoclastogenesis and osteoclastic resorption in vivo and in vitro are investigated. tBHQ upregulates heme oxygenase-1 release and downregulates high mobility group box 1 mRNA expression. mRNA expression of other osteoclast-related genes including nuclear factor-kappa Bp65, receptor activator of nuclear factor kappa-B, nuclear factor of activated T-cells cytoplasmic 1, cathepsin K, and integrin β3, also decreases significantly. Furthermore, tBHQ-treated xTDM/aDFCs scaffolds implanted into rhesus macaques show reduced osteolysis and osteoclastic resorption by microcomputed tomography and tartrate-resistant acid phosphatase staining. tBHQ-induced suppression of xTDM/aDFC-induced osteoclastogenesis and osteoclastic resorption presents a new strategy for the regeneration of biological tooth root and could be applied to the regeneration of other complex tissues and organs.

Pre-clinical efficacy assessment of Malva sylvestris on chronic skin inflammation

In the search for improved quality of life, the treatment of skin diseases like psoriasis (hyperproliferative disease) is valid, since it causes huge social discomfort to the patient. In this context, earlier studies showed that Malva sylvestris L. has anti-inflammatory activity demonstrated by acute animal models of skin inflammation, becoming a promising target for further studies. The present investigation aimed to verify the effect of hydroalcoholic extract of M. sylvestris (HEMS) on the chronic inflammatory and hyperproliferative response caused by multiple applications of 12-O-tetradecanoylphorbol-13-acetate (TPA) on mouse ears. Topical application of HEMS reduced oedema, leukocyte migration (mono- and polymorphonuclear cells) and keratinocyte hyperproliferation, confirmed by histology and proliferating cell nuclear antigen (PCNA) immunostaining. It was found that the anti-inflammatory effects of the extract did not involve the glucocorticoid system, and its incubation with HaCaT keratinocytes caused low toxicity and reduced cell proliferation by apoptosis. Thus, HEMS proved to be effective as an anti-psoriatic therapy, with the ability to prevent keratinocyte hyperproliferation and with low toxicity by topical application.

Optimization extraction and bioactivities of polysaccharide from wild Russula griseocarnosa

The extraction conditions and biological activities of polysaccharides from wild Russula griseocarnosa (PRG) were investigated. Response Surface Methodology (RSM) with a Box-Behnken Design (BBD) was used to optimize extraction conditions. The optimal extraction parameters of PRG were as follows: extracting time 4 h, extraction temperature 77.3 °C and liquid-solid ratio 42.5 g/L. Furthermore, the data demonstrated that PRG exhibited antioxidant activities evidenced by reducing power to scavenge the DPPH, ABTS, hydroxyl radical and superoxide radical. PRG showed the activity of anti-cervical carcinoma cells Hela and Siha. In conclusion this study offered an efficient extraction method of wild Russula griseocarnosa polysaccharide, and the results suggested PRG had good antioxidant and inhibitory activities against cervical carcinoma cells, and PRG could be developed as a novel natural functional food.

Buckwheat cultivars — phenolic compounds profiles and antioxidant properties

Common buckwheat (Fagopyrum esculentum) and tartary buckwheat (Fagopyrum tataricum) cultivars originating in different world countries were investigated and compared for their quantitative and qualitative abundance of phenolics and flavonoids. Moreover, the antioxidant properties were tested using two different methods. The total phenolic and total flavonoid content ranged from 0.897 to 4.226 mg GAE g−1 dw and from 0.238 to 4.626 mg rutin g−1 dw, respectively. Flavonoids — rutin, quercetin, and hydroxybenzoic acids — gallic, protocatechuic, vanillic and syringic were identified and quantified. Rutin was the most abundant flavonoid and protocatechuic acid was the most abundant phenolic acid in evaluated cultivars. All cultivars showed significant antiradical properties, but their chelating activity was weak. The German cultivar of tartary buckwheat Lifago had significantly higher phenolic content and better antioxidant properties than other cultivars. The content of rutin was 24 times higher and free radicals scavenging activity about 70 % higher than the average value of other cultivars.
