Antioxidant Mechanisms Underlying the Gastroprotective Effect of Menthofuran on Experimentally Induced Gastric Lesions in Rodents. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2023; 2023:9192494. [PMID: 37064952 PMCID: PMC10104745 DOI: 10.1155/2023/9192494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 10/30/2022] [Accepted: 01/23/2023] [Indexed: 04/18/2023]
Abstract
Menthofuran is a monoterpene present in various essential oils derived from species from Mentha genus, and in Brazil, those species are widely used in treating gastrointestinal and respiratory disorders. Considering the wide pharmacological potential of monoterpenes, including their antioxidant activity, this study aimed to evaluate menthofuran-gastroprotective activity, as well as the involvement of antioxidant mechanisms in this effect. The acute toxicity was evaluated according to the fixed dose method. The antiulcerogenic activity was investigated by using experimental models of gastric ulcers induced by ethanol, indomethacin, and ischemia/reperfusion in rats. The antisecretory gastric activity, the catalase activity, and the gastric wall mucus were determined in pylorus ligated rats. Gastric wall nonprotein sulfhydryl (NPSH) group content, myeloperoxidase (MPO) activity, and malondialdehyde (MDA) content were evaluated in ethanol-induced the gastric ulcer model. Menthofuran (2 g/kg) presented low acute toxicity and showed gastroprotective activity against ethanol-, indomethacin-, and ischemia/reperfusion-induced ulcers. Moreover, menthofuran presented antisecretory activity, reduced the total acidity, and increased pH of gastric secretion. On the other hand, a decrease in mucus content of gastric wall without alteration of gastric juice volume and catalase activity was observed. Interestingly, menthofuran increased NPSH levels and reduced MDA levels and MPO activity. Gastroprotective effects of menthofuran appear to be mediated, at least in part, by the NOS pathway, endogenous prostaglandins, reduced gastric juice acidity, increased concentration of the NPSH groups, and reduced lipidic peroxidation. These findings support the menthofuran as an effective gastroprotective agent, as well as the marked participation of antioxidant mechanisms in this response.

Abstract
Abstract:
Gastrointestinal (GI) disorders are the ailments of the digestive tract that affect its function like digestion, absorption and excretion. The dysfunction of the gastrointestinal tract may occur due to infections by bacteria, parasites and viruses. Peptic Ulcer Disease is a gastrointestinal tract disorder of stomach and duodenum that is associated with infection of Helicobacter pylori. Helicobacter pylori is regarded as the worldwide causative agent responsible for the etiology of peptic ulcer and gastric carcinoma. The existing drug therapies are good healers in this situation, but due to resistance problems and side effects of drugs, researchers have been working to find out some safe alternatives. Interestingly, the medicinal herbs have been used for treating several disorders, including peptic ulcers and are considered an effective and safer alternative to existing drugs. It is also considered as an eco-friendly, easily available, safe, and less toxic traditional treatment therapy. The combination of herbal medicines with natural products has been shown effective in treating peptic ulcers. In this review, the medicinal plants used against H. pylori infection have been discussed. The mechanism of herbal drugs in healing peptic ulcers by inhibition of H+ K+ ATPase pump, secretion of gastric acid and gastric mucosal protection have also elaborated. The phytochemicals responsible for biological activity have been summarized in the present article. The combination of herbs and natural products in the form of the polyherbal formulation may also be helpful as an effective therapy for treating peptic ulcers. Medicinal plants may offer the researchers new chemical molecules to explore as future drugs or as biochemical agents to unravel the etiology of the disease.

Antiproliferative Activity of Two Unusual Dimeric Flavonoids, Brachydin E and Brachydin F, Isolated from Fridericia platyphylla (Cham.) L.G.Lohmann: In Vitro and Molecular Docking Evaluation. BIOMED RESEARCH INTERNATIONAL 2022; 2022:3319203.

Abstract
Despite the breakthrough in the development of anticancer therapies, plant-derived chemotherapeutics continue to be the basis of treatment for most types of cancers. Fridericia platyphylla is a shrub found in Brazilian cerrado biome which has cytotoxic, anti-inflammatory, and analgesic properties. The aim of this study was to investigate the antiproliferative potential of the crude hydroethanolic extract, subfraction (containing 59.3% of unusual dimeric flavonoids Brachydin E and 40.7% Brachydin F), as well as Brachydin E and Brachydin F isolated from F. platyphylla roots. The cytotoxic activity was evaluated in glioblastoma, lung, prostate, and colorectal human tumor cell lines. The crude hydroethanolic extract did not present cytotoxic activity, but its subfraction presented lower IC50 values for glioblastoma (U-251) and prostate adenocarcinoma (PC-3) cell lines. Brachydins E and F significantly reduced cell viability, proliferation, and clonogenic potential of PC-3, inducing them to the process of regulated cell death. In silico studies have indicated nuclear receptors as targets for Brachydins E and F, and molecular docking has pointed out their binding into glucocorticoid receptor (GR) ligand pocket. Targeting GR pathway has been described as a therapeutic strategy, especially for prostate cancer. These results suggest that Brachydin E and Brachydin F are promising compounds to be further explored for their antitumor effects.

Abstract
Peptic Ulcer Disease (PUD) is the most common disorder of the stomach and duodenum, which is associated with Helicobacter pylori infection. PUD occurs due to an imbalance between offensive and defensive factors and Proton Pump Inhibitors (PPI), Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) and antibiotics are frequently used for the treatment. Recently, medicinal plants have emerged as efficacious, safe and widely available alternative therapies for PUD. The aim of this review was to study the medicinal plants and phytochemicals, which have been used for PUD treatment to evaluate the potential role of natural compounds to develop herbal remedies for PUD. Information was obtained using a literature search of electronic databases, such as Web of Science, Google Scholar, PubMed, Sci Finder, Reaxys and Cochrane. Common and scientific names of the plants and keywords such as 'peptic ulcer', 'gastric ulcer', 'stomach ulcer' and 'duodenal ulcer' were used for search. Eventually, 279 plants from 89 families were identified and information on the plant families, part of the plant used, chemical constituents, extracts, ulcer model used and dosage were abstracted. The results indicated that most of the anti-PUD plants were from Asteraceae (7.1%) and Fabaceae (6.8%) families while flavonoids (49%), tannins (13%), saponins (10%) and alkaloids (9%) were the most common natural compounds in plants with anti-PUD activity.

Abstract
Background:
Peptic ulcer is a deep gastrointestinal erosion disorder that involves
the entire mucosal thickness and can even penetrate the muscular mucosa. Nowadays, several
plants and compounds derived from it have been screened for their antiulcer activity. In
the last few years, there has been an exponential growth in the field of herbal medicine. This
field has gained popularity in both developing and developed countries because of their natural
origin and less side effects.
Objective:
This review aims to provide a comprehensive summary of currently available
knowledge of medicinal plants and phytoconstituents reported for their anti-ulcer properties.
Methods:
The worldwide accepted database like SCOPUS, PUBMED, SCIELO, NISCAIR,
ScienceDirect, Springerlink, Web of Science, Wiley, SciFinder and Google Scholar were
used to retrieve available published literature.
Results:
A comprehensive review of the present paper is an attempt to list the plants with
antiulcer activity. The review narrates the dire need to explore potential chemical moieties
that exert an antiulcer effect, from unexploited traditional plants. Furthermore, the present
study reveals the intense requirement to exploit the exact mechanism through which either
the plant extracts or their active constituents exhibit their antiulcer properties.
Conclusion:
This article is the compilation of the plants and its constituents reported for the
treatment of peptic ulcers. The Comprehensive data will surely attract the number of investigators
to initiate further research that might lead to the drugs for the treatment of ulcers. As
sufficient scientific data is not available on plants, most of the herbals cannot be recommended
for the treatment of diseases. This can be achieved by research on pure chemical
structures derived from plants or to prepare new lead compounds with proven beneficial
preclinical in vitro and in vivo effects. However, a lot remains to be done in further investigations
for the better status of medicinal plants.

Abstract
Objectives: The aim of this study was to assess the effect of Myracrodruon urundeuva All. and Qualea grandiflora Mart. leaves hydroalcoholic extracts on viability and metabolism of a microcosm biofilm and on enamel demineralization prevention. Methodology: Microcosm biofilm was produced on bovine enamel using inoculum from pooled human saliva mixed with McBain saliva, under 0.2% sucrose exposure, for 14 days. The biofilm was daily-treated with the extracts for 1 min. At the end, it was analyzed with respect to viability by fluorescence, CFU counting and extracellular polysaccharides (phenol-sulphuric acid colorimetric assay) and lactic acid (enzymatic assay) production. The demineralization was measured by TMR. The data were compared using ANOVA or Kruskal-Wallis (p<0.05). Results: M. urundeuva All. at 100, 10 and 0.1 μg/mL and Q. grandiflora Mart. at 100 and 0.1 μg/mL reduced biofilm viability similarly to positive control (chlorhexidine) and significantly more than the negative-vehicle control (35% ethanol). M. urundeuva at 1000, 100 and 0.1 μg/mL were able to reduce both lactobacilli and mutans streptococci CFU counting, while Q. grandiflora (1000 and 1.0 μg/mL) significantly reduced mutans streptococci CFU counting. On the other hand, the natural extracts were unable to significantly reduce extracellular polysaccharides and lactic acid productions neither the development of enamel carious lesions. Conclusions: The extracts showed antimicrobial properties on microcosm biofilm, however, they had no effect on biofilm metabolism and caries protection.

Abstract
OBJECTIVES This study evaluated the effect of the hydroalcoholic extracts of Myracrodruon urundeuva All. and Qualea grandiflora Mart. leaves (alone or combined) on the viability of Streptococcus mutans biofilm and on the prevention of enamel demineralization. METHODS Strain of S. mutans (ATCC 21175) was reactivated in BHI broth. Minimum inhibitory concentration, minimum bactericidal concentration, minimum inhibition biofilm concentration and minimum eradication biofilm concentration were determined in order to choose the concentrations to be tested under biofilm model. S. mutans biofilm (5 × 105 CFU/ml) was produced on bovine enamel, using McBain saliva under 0.2% sucrose exposure, for 3 days. The biofilm was daily treated with the extracts for 1 min. The biofilm viability was tested by fluorescence and the enamel demineralization was measured using TMR. RESULTS Myracrodruon urundeuva All. (Isolated or combined) at the concentrationsc ≥0.625 mg/ml was able to reduce bacteria viability, while Qualea Grandflora Mart. alone had antimicrobial effect at 5 mg/ml only (p < 0.05). On the other hand, none of the extracts were able to reduce enamel demineralization. CONCLUSIONS The hydroalcoholic extracts of Myracrodruon urundeuva All. and Qualea grandiflora Mart. leaves (isolated or combined) have antimicrobial action; however, they do not prevent enamel caries under S. mutans biofilm model.

Abstract
Background The rapid spread of drug-resistant strains of protozoan parasites required the urgent need for new effective drugs. Natural products offer a variety of chemical structures, which make them a valuable source of lead compounds for the development of such new drugs. Cerrado is the second largest biome in Brazil and has the richest flora of all the world savannahs. We selected Qualea grandiflora, a plant species known for its proprieties in folk medicine and its antibacterial activity. Objective However, its antiprotozoal activity was not yet explored. Materials and Methods We investigated the activities of fractions from the ethyl acetate extract of Q. grandiflora leaves against human life forms of Plasmodium falciparum, Trypanosoma cruzi, and Trypanosoma brucei gambiense, and for its cytotoxicity upon the rat L6-myoblast cell line. Ten fractions were produced by ethyl acetate:hexane chromatography. Results and Conclusion The fractions showed no cytotoxicity against L-6 cells (IC50 > 100 μg/mL) and no hemolysis propriety. Three fractions had a moderate activity against P. falciparum, anyone was active against T. cruzi but four fractions demonstrated a high activity against bloodstream forms of T. brucei gambiense (8.0< IC50 <15 μg/mL). Identification and characterization of the active compounds are currently under investigation. SUMMARY Qualea grandiflora is an endemic tree of the Brazilian Cerrado, which presents medicinal propertiesTen fractions of the ethyl acetate extract of Q. grandiflora leaves were assessed against Plasmodium falciparum, Trypanosoma Cruzi, and Trypanosoma brucei gambienseNo fraction showed relevant cytotoxicity and hemolysis activityAll the fractions presented antiplasmodial and trypanocidal activitiesThree fractions with moderate antiplasmodial activity (49< IC50 <56 μg/mL)Four fractions with high activity against bloodstream forms of T. brucei gambiense (8.0< IC50 <15 μg/mL).

Abstract
This work describes the antiparasitic and cytotoxic activities of three plant species from the Cerrado biome, Northeastern Brazil. Significant antiparasitic inhibition was observed against Trypanosoma cruzi (63.86%), Leishmania brasiliensis (92.20%) and Leishmania infantum (95.23%) when using ethanol extract from leaves of Guazuma ulmifolia Lam. (Malvaceae), at a concentration of 500 μg/mL. However, low levels of inhibition were observed when assessing leishmanicidal and trypanocidal (Clone CL-B5) activities of crude ethanol extracts from leaves and bast tissue of Luehea paniculata (Malvaceae) and leaves and bark of Prockia crucis (Salicaceae) at a concentration of 500 μg/mL. The extracts revealed the presence of phenolic acids such as gallic acid, chlorogenic acid, caffeic acid and rosmarinic acid, as well as flavonoids such as rutin, luteolin, apigenin and quercetin - the latter detected only in G. ulmifolia. G. ulmifolia extract displayed higher leishmanicidal activity probably due to the presence of quercetin, a potent known leishmanicidal compound. A cytotoxicity test indicated values over 50% at the highest concentration (1000 μg/mL) for all natural products, which were considered cytotoxic. This points out the need for further tests to enable future in vivo trials, including antineoplastic activity on human tumor cells.

Abstract
Background: Qualea parviflora and Qualea grandiflora (Vochysiaceae), commonly known in Brazil as “pau-terra” and “pau-terrinha,” respectively, have been widely used in the treatment of ulcer and gastritis. These therapeutic effects are attributed to various compounds present in the plants, including phenolic compounds such as gallic acid, due to their important antioxidant activity. Objective: The aim of the present study was to validate a high performance liquid chromatography with diode array detection (HPLC-DAD) method for the quantitative determination of gallic acid in the stem bark of Q. parviflora and Q. grandiflora hydroalcoholic extracts. Materials and Methods: The chromatography analysis was successfully achieved on a Dionex column, Acclaim® 120 (250 mm × 4.60 mm, 5 µm) with a gradient elution of water and methanol at a flow rate of 0.8 mL/min and ultraviolet detection at 280 nm. Results: The validation data, including linearity, precision, specificity, accuracy and robustness of this method demonstrated good reliability and sensitivity. Conclusion: The method is able to quantify gallic acid in the stem bark of both species. What is more, the chromatographic peaks showed good resolution and there are also the advantages of easy sample preparation and a short time between each injection.

Abstract
Gastric ulcer is a common disorder of the digestive system. Current therapeutic regimens largely rely on Western medicine. However, numerous studies have demonstrated that herbal medicines can effectively treat gastric ulcer in humans and various animal models via divergent mechanisms. This review updates the efficacy and safety of herbal medicines in treating gastric ulcer, and the mechanisms of their action in humans and animal models. Studies have demonstrated that the efficacy of herbal medicines is comparable or superior to that of drugs such as omeprazole or cimetidine in humans and animal models, and herbal medicines display fewer adverse effects. The mechanisms by which herbal medicines benefit gastric ulcer include stimulation of mucous cell proliferation, anti-oxidation, and inhibition of gastric acid secretion and H(+)/K(+)-ATPase activity. Some herbal medicines also exhibit antimicrobial properties. Utilization of herbal medicines could be a valuable alternative to treat gastric ulcer in humans effectively, with few adverse effects.

Abstract
CONTEXT Potentilla mooniana Wight. (Rosaceae) is a plant found in the Himalayan region where the root is traditionally used to treat stomach problems including gastric-ulcer. OBJECTIVE To scientifically validate the gastro-protective effect and derive the possible mechanistic activity of the ethanol root extract from P. mooniana (EPM). MATERIALS AND METHODS The gastroprotective effect of EPM (100-400 mg/kg, p.o.) was evaluated on both the physical (Pyloric ligation, PL; Cold restrain stress, CRS) and chemical (absolute ethanol, EtOH; aspirin, ASP) ulcerogens induced ulceration in rats. The mechanistic activity of EPM was tested on various gastric-ulcer parameters, namely gastric pH, volume, acid-pepsin output, DNA content, histamine level, H(+)K(+)-ATPase activity, mucus content, microvascular permeability, antioxidant markers, and gastric-histopathological study. RESULTS EPM significantly reduces the ulcer score against all the four tested gastric-ulcer models. In the PL model, EPM showed significant reduction (p < 0.05) in acid-pepsin output and cell shedding; however, no significant effect was observed on gastric volume, cell proliferation, stomach glandular weight, and histamine levels. EPM (400 mg/kg, p.o.) when compared with ulcer control showed significant increase in gastric pH by 41.6% and decrease in H(+)K(+)-ATPase activity by 47.73%. In addition, EPM showed significant increase in mucus content by 58.60% and a decrease in the microvascular permeability of Evans Blue by 85.00%, justifying its protective effects. Furthermore, EPM also showed significant antioxidant activity and histopathologically possessed excellent cytoprotective effect. CONCLUSION The gastro-protective effect of EPM is attributed mainly to the defensive mechanism owing to the presence of a good quantity of polyphenolic components.

Abstract
PURPOSE The antitumor activity of Kielmeyera coriacea (Clusiaceae), a medicinal plant used in the treatment of parasitic, as well as fungal and bacterial infections by the Brazilian Cerrado population, was investigated. METHODS A chloroform extract (CE) of K. coriacea was tested in the murine melanoma cell line (B16F10-Nex2) and a panel of human tumor cell lines. Tumor cell migration was determined by the wound-healing assay and the in vivo antitumor activity of CE was investigated in a melanoma cell metastatic model. 1H NMR and GC/MS were used to determine CE chemical composition. RESULTS We found that CE exhibited strong cytotoxic activity against murine melanoma cells and a panel of human tumor cell lines in vitro. CE also inhibited growth of B16F10-Nex2 cells at sub lethal concentrations, inducing cell cycle arrest at S phase, and inhibition of tumor cell migration. Most importantly, administration of CE significantly reduced the number of melanoma metastatic nodules in vivo. Chemical analysis of CE indicated the presence of the long chain fatty compounds, 1-eicosanol, 1-docosanol, and 2-nonadecanone as main constituents. CONCLUSION These results indicate that K. coriacea is a promising medicinal plant in cancer therapy exhibiting antitumor activity both in vitro and in vivo against different tumor cell lines.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hyptis suaveolens is used by the traditional population in several parts of the world to treat inflammation, gastric ulcer and infection and is used as a crude drug to relieve symptoms related with gastric ulcer or gastritis in northeaster and central region of Brazil. MATERIALS AND METHODS the standardized ethanolic extract (Hs-EtOHE) and hexanic fraction (Hs-HexF) of Hyptis suaveolens (62,5, 125, 250 and 500 mg/kg) was evaluated in several models of acute gastric ulcers. The participation of NO was evaluated by pretreatment with L-NAME and non-protein sulfyhydryls by NEM in the gastroprotective effect. RESULTS Hs-EtOHE and Hs-HexF markedly reduced the gastric lesions induced by all ulcerogenic agents (HCl/ethanol, ethanol, NSAIDs and hypothermic restraint-stress). Gastric ulcerations were exacerbated by administration of NEM suggesting that the gastroprotective mechanism of action of Hs-EtOHE and Hs-HexF involves sulfhydryl groups. CONCLUSION Ours results show that an extract of Hyptis suaveolens, administered orally to rodents, present gastro protective activity in different models of acute of gastric ulcer and give some support to the reported claims on the use of this plant as a gastro protective agent.

Comparison of Brazilian Plants Used to Treat Gastritis on the Oxidative Burst of Helicobacter pylori-Stimulated Neutrophil. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:851621.

Abstract
Ten Brazilian medicinal plants used to treat gastritis and ulcers were carefully selected on the basis of ethnopharmacological importance and antiulcerogenic activity previously described. The antioxidant activity of the methanolic extracts was determined in analysis conditions that simulate a real biological activity on inhibition of the oxidative burst induced in neutrophils using Helicobacter pylori as activator, by a luminol-amplified chemiluminescence assay. The extracts, at low concentration (5 μg/mL), exhibited a large variation in inhibitory effects of H. pylori-induced oxidative burst ranging from 48% inhibition to inactive, but all extracts, excluding Byrsonima intermedia, had inhibitory activity over 80% at the concentration of 100 μg/mL. The total suppressive antioxidant capacity measured as the effective concentration, which represents the extract concentration producing 50% inhibition of the chemiluminescence induced by H. pylori, varies from 27.2 to 56.8 μg/mL and was in the following order: Qualea parviflora > Qualea multiflora > Alchornea triplinervia > Qualea grandiflora > Anacardium humile > Davilla elliptica > Mouriri pusa > Byrsonima basiloba > Alchornea glandulosa > Byrsonima intermedia. The main groups of compounds in tested extracts are presented. Differences in the phytochemical profile, quantitatively and qualitatively, of these plants can explain and justify their protective effect on the gastric mucosa caused by the neutrophil-generated ROS that occurs when H. pylori displays its evasion mechanisms.

Abstract
CONTEXT Bauhinia purpurea L. (Fabaceae) is a native plant species of many Asian countries, including Malaysia and India. In India, the root, stem, bark, and leaf of B. purpurea are used to treat various ailments, including ulcers and stomach cancer. OBJECTIVE In an attempt to establish its pharmacological potential, we studied the antiulcer activity of lipid-soluble extract of B. purpurea obtained via extraction of air-dried leaves using chloroform. MATERIALS AND METHODS The rats were administered the chloroform extract (dose range of 100-1000 mg/kg) orally after 24 h fasting. They were subjected to the absolute ethanol- and indomethacin-induced gastric ulcer, and pyloric ligation assays after 30 min. The acute toxicity study was conducted using a single oral dose of 5000 mg/kg extract and the rats were observed for the period of 14 days. omeprazole (30 mg/kg) was used as the standard control. RESULTS At 5000 mg/kg, the extract produced no sign of toxicity in rats. The extract exhibited significant (p < 0.05) dose-dependent antiulcer activity for the ethanol-induced model. The extract also significantly (p < 0.05) increased the gastric wall mucus production and pH of gastric content, while significantly (p < 0.05) reducing the total volume and total acidity of the gastric content in the pylorus ligation assay. DISCUSSION AND CONCLUSION The extract possesses antiulcer, antisecretory and cytoprotective activities, which could be attributed to its flavonoid and tannin content. These findings provide new information regarding the potential of lipid-soluble compounds of B. purpurea for the prevention and treatment of gastric ulcers.

Abstract
Combretum duarteanum Cambess. is found in South America, particularly in Bolivia, Paraguay, and Brazil. In Paraiba state (Brazil), the species usually occurs in the Caatinga biome. It is popularly known as mofumbo, cipiúba, or cipaúba. This work aims to evaluate the gastroprotective activity and the cytoprotective mechanisms of the ethanolic extract (Cd-EtOHE) and hexane phase (Cd-HexP) obtained from the leaves of C. duarteanum. Doses at 62.5, 125, 250, and 500 mg/kg of Cd-EtOHE and Cd-HexP were tested in models of gastric ulcers induced by HCl/ethanol, absolute ethanol, stress, non-steroidal anti-inflammatory drugs, and pylorus ligation in male rats or mice. Cd-EtOHE and Cd-HexP significantly reduced gastric injuries induced in all models. Cd-EtOHE and Cd-HexP did not alter gastric juice parameters such as pH, [H(+)], or volume after pylorus ligation. Cytoprotective mechanisms of Cd-EtOHE and Cd-HexP in relation to mucus, nitric oxide (NO), and sulfhydryl (SH) groups were evaluated. Neither product increased the mucus, and they both showed dependence on NO and SH groups to prevent gastric ulcer. Both Cd-EtOHE and Cd-HexP demonstrated gastroprotective activity.

Abstract
The potential of tuber flour of Ipomoea batatas (L.) Lam. cv. Brazlândia Branca (white sweet potato) as wound healing and antiulcerogenic agent was investigated in vivo in animal model. Excision on the back of Wistar rats was performed to induce wounds that were topically treated with Beeler’s base containing tuber flour of white sweet potato at 2.5%. Number of cells undergoing metaphase and the degree of tissue re-epithelialization were investigated 4, 7 and 10 days post-treatment. The protective effect of aqueous suspension of tuber flour (75 and 100 mg/kg animal weight) on gastric mucosa of Wistar rats was also studied by using the ethanol-induced ulceration model. Ointment based on white sweet potato at 2.5% effectively triggered the healing of cutaneous wound as attested by the increased number of cells undergoing metaphase and tissue re-epithelialization regardless the time of wound treatment. Tuber flour potentially prevented ethanol-induced gastric ulceration by suppressing edema formation and partly protecting gastric mucosa wrinkles. Crude extracts also exhibited potential as free radical scavengers. The results from animal model experiments indicate the potential of tuber flour of white sweet potato to heal wounds.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhizome of Zingiber montanum has been extensively used as a folk medicine to ameliorate peptic ulcer at northern part of Bangladesh. AIM OF THE STUDY To identify the antiulcer principle of the MeOH extract of the rhizome of Zingiber montanum by an ex vivo bioassay guided chromatographic separation and purification, and structure elucidation of the purified compound by spectroscopic methods. MATERIALS AND METHODS Dried powder of Zingiber montanum rhizomes was extracted with MeOH. The antiulcer activity of the crude extract and its chromatographic fractions were evaluated by the inhibition of 1N HCl induced gastric lesions in Swiss albino mice. The pure compound was purified from the active fraction by crystallization with hexanes. Structure of the pure compound was elucidated by spectroscopic methods. The antiulcer activity of the pure compound was evaluated by the inhibition of 1N HCl, 95% ethanol and indomethacin induced gastric lesions in mice. RESULTS The MeOH extract of Zingiber montanum showed 61.97% and 83.10% inhibition of the 1N HCl induced gastric lesions at doses of 200mg/kg and 400mg/kg, respectively, in mice. Chromatographic separation on silica gel of the extract was yielded seven fractions and the fraction 2 was found to have most potent antiulcer activity in mice. This fraction showed 77.46% inhibition of the 1N HCl induced gastric lesions at a dose of 40mg/kg in mice. Crystallization of the fraction yielded 1 (zerumbone, 180mg). It showed statistically 45.77% and 92.25% inhibition of 1N HCl induced gastric lesions in mice at doses of 20mg/kg and 40mg/kg, respectively. It also showed 29.07% and 45.35% inhibition of 95% ethanol induced gastric mucosal damage, and 64.76% and 72.38% inhibition of indomethacin induced gastric lesions in mice at doses of 20mg/kg and 40mg/kg, respectively. CONCLUSION Zerumbone (1) showed potent cytoprotective effect against necrotizing agent (HCl) and non-steroidal anti-inflammatory drug (indomethacin) induced gastric ulceration. It also exhibited moderate cytoprotective effect against noxious agent (EtOH) induced gastric lesions. It can be considered as a promising new antiulcer natural drug lead.

ASIAN PAC J TROP MED 2012; 4:883-8. [PMID: 22078951 DOI: 10.1016/s1995-7645(11)60213-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2011] [Revised: 08/15/2011] [Accepted: 10/15/2011] [Indexed: 11/26/2022] Open
Abstract
OBJECTIVE To explore the effects of extract of Hibiscus rosasinensis (H. rosasinensis) on the volume, free and total acidity of gastric secretion induced by carbachol. METHODS Animals were kept on fasting for 48 h, then the pylorus of each animal was ligated. They were randomly divided into 5 groups and treated by carbachol at 600 μg/kg. Then animals in group II - V were treated by H. rosasinensis extract at 250 and 500 mg/kg body weight, cimetidine at 2.5 mg/kg and verapamil at 10 mg/kg body weight intraperitoneally, respectively. The volume, free and total acidity of gastric secretion were observed and compared. RESULTS It was found that the extract significantly reduced the volume, free and total acidity of gastric secretion (P<0.01). These reductions were comparable to cimetidine and verapamil. And the reduction in the volume and free acidity were more significant in cimetidine and verapamil treated group indicating that cimetidine and verapamil were more effective. CONCLUSIONS The extract of H. rosasinensis can reduced the volume, free and total acidity of gastric secretion, and can be used effectively in the treatment of peptic ulcer.

Abstract
This review of the current literature aims to study correlations between the chemical structure and gastric anti-ulcer activity of tannins. Tannins are used in medicine primarily because of their astringent properties. These properties are due to the fact that tannins react with the tissue proteins with which they come into contact. In gastric ulcers, this tannin-protein complex layer protects the stomach by promoting greater resistance to chemical and mechanical injury or irritation. Moreover, in several experimental models of gastric ulcer, tannins have been shown to present antioxidant activity, promote tissue repair, exhibit anti Helicobacter pylori effects, and they are involved in gastrointestinal tract anti-inflammatory processes. The presence of tannins explains the anti-ulcer effects of many natural products.

[PMID: 21911046 DOI: 10.1016/j.jep.2011.08.062] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/01/2011] [Revised: 08/16/2011] [Accepted: 08/25/2011] [Indexed: 05/31/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The species Qualea grandiflora and Qualea multiflora, which belong to the Vochysiaceae family, are common in the Brazilian savannah (Cerrado biome), and the local inhabitants use these species to treat external ulcers and gastric diseases and as an anti-inflammatory agent. Studies have demonstrated that these plants contain compounds that exhibit pharmacological activities; however, the risks associated with their consumption are not known. MATERIAL AND METHODS In the present study, the mutagenicity of polar and apolar extracts from Qualea grandiflora and Qualea multiflora were assessed by employing the Ames assay with and without metabolic activation. Additionally, phytochemical analyses (HPLC-ESI-IT-MS, HPLC-UV-PDA and GC-IT-MS) were performed to identify the chemical constituents present in these species, including the evaluation of physico-chemical properties, such as polarity or apolarity of the organic compounds, which are related to each fraction obtained. These studies provide important information regarding the biochemical behaviour of these compounds. RESULTS All extracts exhibited mutagenicity, inducing frameshift mutations and base substitutions in DNA. Phytochemical analysis identified terpenes, ellagic acid derivatives and phytosteroids. CONCLUSIONS The mutagenicity observed might be due to the presence of pentacyclic triterpenes and polyphenols, which are able to generate reactive oxygen species (ROS) and result in the potential to cause DNA damage. The genetic risk identified in this present work shows that special attention should be considered for the use of compounds obtained from these plant species in medicinal treatments. Further studies must be conducted to identify safe therapeutic doses.

Abstract
AIM OF THE STUDY Quassia amara L. is commonly used in Costarican folk medicine. It has been used for the treatment of a broad range of gastrointestinal symptoms such as dyspepsia, gastritis and constipation. In this study, the gastroprotective activity of two standardized extracts of Quassia amara L., Lipro(®) and Ligas(®), was evaluated. MATERIALS AND METHODS Anti-ulcerogenic properties were evaluated in female rats under acute ulcer-induction models (ethanol, indomethacin and hypotermic restraint). To get a deeper insight in the anti-ulcerogenic properties of the extracts, Ligas(®) was evaluated in the Shay rat model. Five parameters were estimated with this model: gastric mucus barrier, non-protein sulfhydril groups (NPSG) in the gastric mucosa, and pH, total acidity and peptic activity of the gastric juice. RESULTS Induction of ulcers by 95% ethanol (0.5 mL per os), indomethacin (100 mg/kgs.c.) and stress (2h in hypothermic restraint) was inhibited significantly with administration of Lipro(®) (p<0.05), in a dosage range from 4.9 mg/kg/d to 48.9 mg/kg/d. Treatment was given for one week. The extract Ligas(®) showed a significant augmentation of NPSG (p<0.05) in a dosage range from 4.0 to 39.7 mg/kg. Ligas(®) did not produce a significant change (p>0.05) in the other indicators. CONCLUSIONS Quassia amara L. standardized extracts, Lipro(®) and Ligas(®), showed an important anti-ulcerogenic effect in acute ulcer induction models. Their effect was related to an increase in gastric barrier mucus and non-protein sulfhydril groups.

Abstract
ETHNOPHARMACOLOGICAL IMPORTANCE Many species of plants in the Brazilian cerrado (savanna) are widely used in ethnomedicine. However, the safety and effectiveness of medicinal plants used in communities with little or no access to manufactured drugs should be evaluated. AIM OF THE STUDY Evaluate the antimicrobial and cytotoxic activities of extracts from eight plant species, obtained using Brazilian cachaça as the extractor liquid. MATERIALS AND METHODS The extracts were tested against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Candida parapsilosis, promastigote forms of Leishmania amazonensis, and poliovirus. In addition, cytotoxic activity was assayed in Vero cells and in human erythrocytes. RESULTS The plant species Curatella americana, Sclerolobium aureum, and Plathymenia reticulata showed the best activity against yeasts, especially the crude extract of C. americana and its ethyl-acetate fraction. Kielmeyera lathrophyton showed a minimum inhibitory concentration of 250 μg/ml against S. aureus, and was inactive against gram-negative bacteria. The extract obtained from Annona coriacea showed the best activity against the promastigote forms of Leishmania amazonensis (IC(50)=175 μg/ml). Only C. americana showed potential for antipoliovirus activity. The concentrations of the crude extracts that showed toxicity to VERO cells had CC(50) between 31 and 470 μg/ml, and the lyophilized Brazilian cachaça showed a CC(50) of 307 μg/ml. None of the extracts showed toxicity against human erythrocytes. CONCLUSIONS Among the plant species studied, C. americana proved to be effective against microorganisms, especially as an antifungal. The results will help in the search for alternative drugs to be used in pharmacotherapy, and will contribute to establish safe and effective use of phytomedicines in the treatment of infectious diseases.

Abstract
AIM OF THE STUDY Mouriri pusa, popularly known as "manapuçá" or "jaboticaba do mato", is a plant from Brazilian cerrado that has been found to be commonly used in the treatment of gastrointestinal disturbs in its native region. The present work was carried out to investigate the effect of tannins (TF) and flavonoids (FF) fractions from Mouriri pusa leaves methanolic extract on the prevention and cicatrisation process of gastric ulcers, and also evaluate possible toxic effects. MATERIALS AND METHODS The following protocols were taken in rats: acute assay, in which ulcers were induced by oral ethanol after pre-treatment with the fractions; and 14 days treatment assay, in which ulcers were treated for 14 days after induction by local injection of acetic acid. RESULTS In the acute model, treatment with either, TF (25mg/kg) or FF (50mg/kg), was able to reduce lesion area, showing gastroprotective effect. In addition, FF proved itself anti-inflammatory by reducing COX-2 levels. In acetic acid model, both fractions exhibited larger ulcers' regenerative mucosa, indicating cicatrisation enhancement. FF group also showed augmented cell proliferation, anti-inflammatory action and enhanced angiogenesis as well as increased mucus secretion. Moreover, concerning the toxicity parameters analyzed, no alteration in the fractions groups was observed. CONCLUSIONS Tannins and flavonoids from Mouriri pusa provide beneficial effects against gastric ulcers with relative safety.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Achyrocline satureoides is a medium-sized South American indigenous herb, commonly known as "Marcela" or "Macela". The infusion obtained from inflorescences of this plant is widely used in Brazilian folk medicine as an antispasmodic, anti-inflammatory, hypoglycemic, and hypocholesterolemic, mainly to treat gastrointestinal disorders such as gastric ulcers and dyspepsia. However, the antiulcer properties of this species have not yet been fully studied. AIM OF THE STUDY This study was conducted to evaluate and contribute to validating the antiulcer activity of hydroalcoholic extract of inflorescences of Achyrocline satureoides. MATERIALS AND METHODS The antiulcer assays were performed using the ethanol-induced ulcer, and nonsteroidal anti-inflammatory drug (NSAID)-induced ulcer protocols. Gastric secretion parameters were also evaluated (volume, pH and total acidity) by the pylorus ligated model, and the mucus in the gastric content was determined. RESULTS In the ethanol-induced ulcer model, it was observed that the treatment with Achyrocline satureoides extract significantly reduced the lesion index by 75.1+/-8.6, 85.0+/-9.2, 86.6+/-7.4 and 75.5+/-5.3 for the groups treated with 100, 250 and 500 mg/kg of extract of inflorescences of Achyrocline satureoides and the positive control (omeprazole 30 mg/kg), respectively. Significant inhibition was also observed in the lesion index in the indomethacin-induced ulcer model, with decreases of 62.5+/-7.1, 62.5+/-6.1, 63.6+/-5.5 and 96.2+/-3.6 for the groups treated with 100, 250 and 500 mg/kg of extract and the positive control (cimetidine 100 mg/kg), respectively. The parameters of gastric secretion (pH, volume, [H(+)]) showed no alteration in the different doses of the treatment. On the other hand the treatment with the hydroalcoholic extract of Achyrocline satureoides (100, 250 and 500 mg/kg), significantly increased mucus production (p<0.01), when compared with the groups treated with indomethacin (100 mg/kg), cimetidine (100 mg/kg) and negative control (vehicle). No signs of toxicity was observed in the acute toxicity study. CONCLUSIONS The results of the present study show that hydroalcoholic extract of Achyrocline satureoides displays antiulcer activity, as demonstrated by the significant inhibition of the formation of ulcers induced using different models. However, this activity appears not be related to the antisecretor mechanisms. Moreover, this work suggests that preparations obtained from Achyrocline satureoides could be used for the development of new phytotherapic drugs for the treatment of gastric ulcer.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Qualea parviflora Mart. is a medicinal species commonly found in the Brazilian Cerrado biome. AIM OF THE STUDY Based on ethnopharmacological data, methanolic extract from Qualea parviflora (QP) bark was evaluated for its antiulcer, analgesic, anti-hemorrhagic, mutagenic and anti-Helicobacter pylori activities. MATERIAL AND METHODS The gastroprotective action of the extract was evaluated in rodent experimental models (HCl/ethanol, ethanol or NSAID). We also evaluated mutagenic effect (Ames assay), anti-Helicobacter pylori, anti-hemorrhagic action, analgesic and inflammatory effects (hot-plate test and carrageenin-induced hind paw edema) of methanolic extract from Qualea parviflora. RESULTS QP (500 mg/kg, p.o.) was able to protect gastric mucosa against HCl/ethanol solution (77%), absolute ethanol (97%), and also against injurious effect of NSAID (36%). When QP was challenged with sulfhydryl depletor compound, the gastroprotective action of extract was abolished. QP treatment was able to maintain the GSH level and show a concentration-dependent inhibition effect on the lipid peroxidation. QP present anti-Helicobacter pylori effect (MIC=75 microg/mL), anti-hemorrhagic and antidiarrheal action but not present analgesic or anti-inflammatory effect. CONCLUSION methanolic extract from Qualea parviflora had gastroprotective effect related to the increase of gastric mucosa defensive factors such PGE(2) levels and maintain the basal gastric glutathione levels. The methanolic extract also showed anti-Helicobacter pylori activity, anti-hemorrhagic effect and antioxidant action, but absence of analgesic, mutagenic and toxic effects, a profile that adds safety to its use.

Abstract
AIM: To examine the antiulcerogenic effects of various extracts of Mentha arvensis Linn on acid, ethanol and pylorus ligated ulcer models in rats and mice.
METHODS: Various crude extracts of petroleum ether, chloroform, or aqueous at a dose of 2 g/kg po did not produce any signs or symptoms of toxicity in treated animals. In the pyloric ligation model oral administration of different extracts such as petroleum ether, chloroform and aqueous at 375 mg/kg po, standard drug ranitidine 60 mg/kg po and control group 1% Tween 80, 5 mL/kg po to separate groups of Wister rats of either sex (n = 6) was performed. Total acidity, ulcer number, scoring, incidence, area, and ulcer index were assessed.
RESULTS: There was a decrease in gastric secretion and ulcer index among the treated groups i.e. petroleum ether (53.4%), chloroform (59.2%), aqueous (67.0%) and in standard drug (68.7%) when compared to the negative control. In the 0.6 mol/L HCl induced ulcer model in rats (n = 6) there was a reduction in ulcerative score in animals receiving petroleum ether (50.5%), chloroform (57.4%), aqueous (67.5%) and standard. drug (71.2%) when compared to the negative control. In the case of the 90% ethanol-induced ulceration model (n = 6) in mice, there was a decrease in ulcer score in test groups of petroleum ether (53.11%), chloroform (62.9%), aqueous (65.4%) and standard drug ranitidine (69.7%) when compared to the negative control. It was found that pre-treatment with various extracts of Mentha arvensis Linn in three rat/mice ulcer models ie ibuprofen plus pyloric ligation, 0.6 mol/L HCl and 90% ethanol produced significant action against acid secretion (49.3 ± 0.49 vs 12.0 ± 0.57, P < 0.001). Pre-treatment with various extracts of Mentha arvensis Linn showed highly -significant activity against gastric ulcers (37.1 ± 0.87 vs 12.0 ± 0.57, P < 0.001).
CONCLUSION: Various extracts of Mentha arvensis Linn. 375 mg/kg body weight clearly shows a protective effect against acid secretion and gastric ulcers in ibuprofen plus pyloric ligation, 0.6 mol/L HCl induced and 90% ethanol-induced ulcer models.
