Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Peptic ulcer disease (PUD) ranks top among the most prominent gastrointestinal problems prevalent around the world. Long-term use of non-steroidal anti-inflammatory drugs, pathogenic infection by Helicobacter pylori, imbalances between gastrointestinal regulatory factors and pathological hyperacidity are major contributors towards the development of peptic ulcers. Although synthetic drugs of multiple pharmacological classes are abundantly available, inadequacy of such agents in ensuring complete recovery in not uncommon. Therefore, pharmacological explorations of herbal products including plant extracts and their respective isolated phytoconstituents, for potential gastroprotective and antiulcer properties, are regular practice among the scientific community. Moreover, the historical preferences of a significant share of world population towards herbal-based medication over modern synthetic drugs also contribute significantly to such endeavors. AIM OF THE REVIEW This review has endeavored to present ethnomedicinal and pharmacological prospects of a significant number of authenticated plant species in terms of their capacity to exert gastroprotection and antiulcer activities both in vitro and in vivo. The information delineated along the way was further subjected to critical analysis to ascertain the possible future prospects of such findings into designing plant-derived products in future for the treatment of peptic ulcer. MATERIALS AND METHODS Electronic version of prominent bibliographic databases, including Google Scholar, PubMed, Scopus, ScienceDirect, Wiley Online Library, SpringerLink, Web of Science, and MEDLINE were explored extensively for the identification and compilation of relevant information. The plant names and respective family names were verified through the Plant List (version 1.1) and World Flora Online 2021. All relevant chemical structures were verified through PubChem and SciFinder databases and illustrated with ChemDraw Ultra 12.0. RESULTS A colossal number of 97 plant species categorized under 58 diverse plant families have been discussed in the review for their gastroprotective and antiulcer properties. In vivo illustrations of the pharmacological properties were achieved for almost all the species under consideration. 29 individual phytoconstituents from these sources were also characterized with similar pharmacological potentials. Majority of the plant extracts as well as their constituents were found to exert their gastroprotective effects through antioxidative pathway featuring both enzymatic and nonenzymatic mechanism. Moreover, active inhibition of acid secretion, upregulation of gastroprotective mediators and downregulation of pro-inflammatory cytokines, were also associated with a prominent number of plants or products thereof. CONCLUSIONS Comparative evaluations of the plant sources for their antiulcer activities, both as individual and as combination formulations, are necessary to be conducted in human subjects under properly regulated clinical conditions. Moreover, the efficacy and safety of such products should also be evaluated against those of the currently available treatment options. This will further facilitate in ascertaining their suitability and superiority, if any, in the treatment of peptic ulcer diseases. Implementation of these endeavors may eventually lead to development of more efficient treatment options in the future.

Abstract
Objective The aim of this study was to evaluate the antiulcer activity of hydromethanol extracts of Solanum incanum L. (Solanaceae) leaves and roots in mice. Methods The antiulcerogenic activity of the plant extracts were evaluated using Pylorus ligation and ethanol induced gastric ulcers in fasted mice. Data were analyzed using one way ANOVA, and P-values <0.05 were considered statistically significant. Result:Pylorus ligation-induced ulcer Single dose and repeated daily dose administration of the leaf and root extracts for 10 days didn't significantly (P > 0.05) affect pH, total acidity and volume of gastric secretion. Single dose of both extracts significantly reduced ulcer score (P = 0.036) and ulcer index (leaf, P = 0.037; root, P = 0.041) at the dose of 400 mg/kg. Similarly, significant reduction in ulcer score was observed after repeated daily treatment with 200 mg/kg (P = 0.030) and 400 mg/kg (P = 0.005) of the leaf extract and 400 mg/kg (P = 0.005) of the root extract. In addition, repeated administration of 400 mg/kg of the leaf (P = 0.004) and root (P = 0.005) extracts significantly reduced ulcer index. Ethanol-induced ulcer Single dose of both extracts significantly reduced ulcer score at the dose of 200 mg/kg (leaf, P = 0.017; root, P = 0.036) and 400 mg/kg (leaf, P = 0.001; root, P = 0.001). Similarly, 200 mg/kg (leaf, P = 0.002; root, P = 0.018) and 400 mg/kg (leaf, P = 0.001; root, P = 0.001) of the extracts significantly reduced ulcer index after single dose treatment. Repeated daily treatment with leaf and root extracts for ten days caused a significant (P = 0.037, 0.001 and 0.001 for 100, 200 and 400 mg/kg leaf extract; P = 0.026, 0.018 and 0.001 for 100, 200 and 400 mg/kg root extract, respectively) reduction in ulcer score. In addition, both extracts significantly (P = 0.041, 0.004 and 0.000 for 100, 200 and 400 mg/kg leaf extract; P = 0.038, 0.008 and 0.000 for 100, 200 and 400 mg/kg root extract, respectively) reduced ulcer index after 10 days of treatment. Conclusion This study has revealed hydromethanol extracts of Solanum incanum leaves and roots have antiulcerogenic activity using in vivo models. The antiulcer activity of the plant is not related to acid anti-secretory action, suggesting the plant may have cytoprotective effect on the gastric mucosa.

Abstract
Jatropha elliptica (Pohl) Oken (Euphorbiaceae) roots are used in folk medicine to treat gastric ulcers. The purpose of this work was to evaluate the gastroprotective activity of ethanol extract (JER) and hexane fraction (ERH) of J. elliptica roots in mice, as well as to analyze the acute toxicity of the extract and identify the potential active compounds. No signs of toxicity were observed in JER. In both acidified ethanol and indometacin-induced gastric ulcer models, all doses tested of JER and ERH significantly reduced gastric lesions. Dereplication of JER was performed by HPLC-DAD-ESI-MS/MS and resulted in the annotation of compounds fraxetin, propacin, jatrophone and jatropholones A and B. GC-MS analysis of ERH revealed the diterpenes jatrophone, jatropholone A and jatropholone B as the major components. The chemical study of this fraction has led to the isolation of these compounds, in addition to the sequiterpene cyperenoic acid and the diterpene 2β-hydroxyjatrophone, both reported for the first time in J. elliptica. The isolated compounds were tested against L929 cells and only cyperenoic acid and the mixture of jatropholones A and B did not show toxicity, being then selected as good candidates for bioassays using acidified ethanol-induced gastric ulcer model. Cyperenoic acid significantly decreased gastric lesions and preserved gastric mucus layer. The mixture of jatropholones A and B caused a smaller reduction of gastric lesions, without preservation of the gastric mucus layer. The study showed that J. elliptica roots present gastroprotective activity in mice, without causing acute toxic effects. The activity is related, at least in part, to the occurrence of terpenes, mainly the sesquiterpene cyperenoic acid.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Virola elongata is a tree species belonging to the Myristicaceae family, distributed in the North and Midwest regions of Brazil, in the phytogeographic domain of the Amazon. The aqueous infusion or the hydroethanolic macerate of the stem bark of V. elongata are used in Brazilian and Ecuadorian indigenous folk medicine for several ethnopharmacological purposes, principally, in the treatment of stomach pain, indigestions, and gastric ulcers. This study was aimed to investigate the gastroprotective activity of this plant in order to support its popular use with scientific evidence. MATERIALS AND METHODS The stem bark hydroethanolic extract of the plant (HEVe) was prepared by maceration. Its qualitative and quantitative phytochemical constituents were investigated by classical colorimetric techniques, HPLC, and electrospray ionization-multiple stage fragmentation (ESI-MSn). The gastroprotective and antiulcer activity of HEVe at doses of 100, 300 and 900 mg/kg p.o. were tested using three acute (acidified ethanol, piroxicam, and in-water-restrain stress), and one chronic (acetic acid) animal ulcer models. The probable mode of action of the HEVe was evaluated by analyzing gastric acid secretion, mucus content, nitric oxide effect, and its antioxidant properties (on catalase, myeloperoxidase, and GSH content) in experimental rodents. The direct extract's activity on the growth of Helicobacter pylori was also investigated. RESULTS Total phenolic content in the HEVe was of 146.20 ± 1.07 mg, being flavonoids about 50% (71.79 ± 0.70 mg) of it. Comparative HPLC fingerprint analysis revealed the presence of known phenolic antiulcer compounds, such as gallic acid, catechin, and rutin. Also, methanol/water fractionation and ESI-MSn analysis of the HEVe reveals the presence of quinic acid, 3,3',4-trihydroxystilbene, juruenolid D, one catechin dimer, one C-glycosyl flavonoid, one polyketide and two neolignans as the major components of the extract. The HEVe attenuated gastric ulceration in all the different models of acute gastric ulcer, by enhancing gastroprotection through its antioxidant properties in vivo, and reducing also considerably the gastric secretion and total acidity. The HEVe also presented healing properties against the induced chronic ulceration process. On the other hand, the HEVe did not exhibit direct activity against H. pylori. CONCLUSION The HEVe exhibited significant gastroprotective/antiulcer effects and contain a relative high proportion of phenolic compounds, especially flavonoids, that could likely account, at least in part, for its pharmacological properties. The results justify its traditional usage and provided scientific evidence for its potential as a new herbal medicine to treat gastric ulcers.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sedum dendroideum Moc & Sessé ex DC (Crassulaceae) is a medicinal plant employed in Mexican and Brasilian folk medicine as juice or infusion, as remedy for the treatment of different diseases, including gastric disorders. AIM OF THE STUDY Although some studies carried out with Sedum dendroideum have demonstrated its gastroprotective effect, the purpose of this study was to elucidate the chemical constituents, antioxidant, cytotoxic and mechanisms underlying the gastrointestinal properties of Sedum dendroideum accordingly its traditional use, as fresh leaves tea infusion (SDI). MATERIALS AND METHODS Chemical constituents were analyzed using high performance liquid chromatography and mass spectrometry (HPLC-MS). Antioxidant and cytotoxicity were evaluated in in vitro assays. The efficacy of the SDI on macroscopic ulcer appearance, mucus and GSH maintenance on ethanol- and indomethacin-induced ulcer models, gastric acid secretion and gastrointestinal motility were investigated. RESULTS Phytochemical analysis by HPLC-MS revealed the presence of different flavonol glycosides, containing myricetin and quercetin, along with the kaempferol as aglycones. In vitro pharmacological investigation of SDI demonstrated potent antioxidant activity in DPPH assay (IC50: 13.25 ± 3.37 µg/mL) and absence of cytotoxicity in Caco-2 cells by MTT method. Oral administration of SDI (ED50 of 191.00 ± 0.08 mg/kg) in rats promoted gastroprotection against ethanol or indomethacin in rats through reinforcement of gastric wall mucus, GSH content and nitric oxide release, without present antisecretory properties. The gastroprotective effect was maintained when SDI (19 mg/kg) was administrated by intraperitoneal route. Furthermore, SDI (150 mg/kg) unchanged the gastric emptying but increase small bowel transit in mice through cholinergic pathways. CONCLUSIONS Collectively, this study confirmed that Sedum dendroideum promotes gastroprotection through preventing of endogenous defense mechanisms, represented by mucus and GSH without changes gastric acid secretion. Sedum dendroideum tea infusion features a chemical profile that contributes to the antioxidant and gastric health-promoting effects, supporting the use in folk medicine for the treatment of gastrointestinal disorders.

Abstract
CONTEXT Aloe has been used for the prevention and cure of various diseases and symptoms including burns, injuries, oedema and pain. OBJECTIVE This study determines the specific inhibitory activity of matrix metalloproteinase (MMP)-9 induced by the low molecular-weight gel fraction of Aloe vera (L.) Burm.f. (lgfAv) on alcohol-induced acute gastric lesions. MATERIALS AND METHODS We examined the protective effects of oral (p.o.) administration of lgfAv (molecular weight cutoff <50.0 kDa, 150.0 mg/kg body weight) in a Balb/c mouse model of alcohol-induced acute gastritis for 1 h exposure. By measuring ulcer index, we compared the antiulcerative activity of the fraction. mRNA expression and immunohistochemical analysis of various biomarkers were performed. RESULTS The lgfAv-treated mice exhibited drastically fewer ulcer lesions than the untreated control mice did. It featured that lgfAv lessened the ulcer lesions than their relevant controls. Moreover, the transcriptional level of MMP-9 was completely alleviated by lgfAv treatment in alcohol-treated gastritis-induced mice. DISCUSSION The transcriptional level of MMP-9 was significantly alleviated by lgfAv treatment of the model. However, reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry experiments revealed that lgfAv treatment in mucosal tissues had the potential to inhibit the mRNA and protein expression levels of MMP-9, respectively. The protein expression of MMP-9 was closely associated with lgfAv-induced gastroprotection against alcohol-induced gastric lesions. CONCLUSIONS The present findings suggest that lgfAv has the potential to alleviate alcohol-induced acute gastric lesions, which is mediated in part, mainly by the suppression of the mRNA expression of MMP-9.

The anti-inflammatory and anti-ulcer evaluations of the newly synthesized products were evaluated and the results showed that compounds 4, 8c, 10, 11, 13c, 15a, 15c, 17a, 17b, 17e, 18a and 18f possessed higher activity compared to the rest of the compounds. In addition to this, the toxicity of these active compounds was studied against shrimp larvae where compounds 15a, 15c and 18a showed non-toxicity against the tested organisms.

Abstract
OBJECTIVE To evaluate the antimalarial and antiulcerogenic activities of leaf extract and fractions of Melanthera scandens (M. scandens). METHODS The crude leaf extract (37-111 mg/kg) and fractions (chloroform, ethylacetate and methanol; 78 mg/kg) of M. scadens were investigated for antiplasmodial activity against chloroquine-sensitive Plasmodium berghei infections in mice and for antiulcer activity against experimentally-induced ulcers. The antimalarial activity during early and established infections as well as prophylactic was investigated. Artesunate (5 mg/kg) and pyrimethamine (1.2 mg/kg) were used as positive controls. Thin films made from tail blood of each mouse were used to assess the level of parasitaemia of the mice. Antiulcer activity of the crude extract was also evaluated against indomethacin, ethanol and histamine induced ulcers. RESULTS The extract and its fractions dose-dependently reduced parasitaemia induced by chloroquine-sensitive Plasmodium berghei infection in prophylactic, suppressive and curative models in mice. These reductions were statistically significant (P<0.001). They also improved the mean survival time (MST) from 9.28 to 17.73 days as compared with the control (P<0.01-0.001). The activities of extract/fractions were incomparable to that of the standard drugs i.e. artesunate and pyrimethamine. On experimentally-induced ulcers, the extract inhibited indomethacin, ethanol and histamine induced ulcers. These inhibitions were statistically significant (P<0.001) and in a dose-dependent fashion. CONCLUSIONS The antiplasmodial and antiulcerogenic effects of this plant may in part be mediated through the chemical constituents of the plant.

Abstract
Antiulcer activity of novel quinoline-chalcone hybrids (13-37) was investigated. Among them, eight compounds (14, 16, 17, 23, 29, 31, 32 and 35) were found to be active in various ulcer models in Sprague-Dawley (SD) rats. To understand the mechanism of action of these hybrids, the effects of the compounds on antisecretory and cytoprotective activities were studied. All these active hybrids improved the depleted levels of mucin and consequently inhibited the formation of erosions in a pyloric ligated ulcer model. In addition, they also significantly increased the gastric PGE2 content in an aspirin induced ulcer model. The additional experiments including the in vitro metabolic stability and in vivo pharmacokinetics led to the identification of compound 17 as an orally active and safe candidate that is worthy of further investigation to be developed as an antiulcer agent.

Abstract
INTRODUCTION Antioxidants are reported to have antiulcer activity. We investigated silymarin, a bioflavonoid antioxidant, for antiulcer potential. MATERIALS AND METHODS Pylorus-ligated Shay rats (n=5) were used as the experimental gastric ulcer animal model. The rats, separated into three groups, were administrated silymarin (50 mg/kg), omeprazole (3.6 mg/kg), or saline (5 ml/kg) per orally daily for 5 days prior to ulcerogenic challenge. Nineteen hours after the challenge, the rats were sacrificed and their stomachs isolated. Formed gastric juice was collected for measurement of volume, titrimetric estimation of free and total acidity, and total acid output by the conventional methods. The ulcer index was calculated. Total acid output and free and combined acid quantities were calculated using the acidity value and the volume of formed gastric juice. RESULTS Silymarin exerted significant (P<.05) antiulcer activity (the ulcer index was reduced to 7.4 ± 1.0 from the control value of 19.8 ± 4.1). Silymarin also significantly reduced free and total acidity, gastric juice volume, total acid output, and combined acid content. The results were analyzed by ANOVA and Newman-Keuls multiple comparison test. CONCLUSION This study demonstrates that silymarin has significant antiulcer activity. It perhaps acts by decreasing hydrochloric acid output and increasing buffering power (combined acid).

Abstract
Gastric ulcer is one of the most prevalent gastrointestinal disorders, which affects approximately 5%-10% of people during their life. The ulcer is an open sore that develops on the inside lining of the stomach (a gastric ulcer) or the small intestine (a duodenal ulcer). Both types of ulcers are also referred to as peptic ulcer disease. The present study was carried out to investigate antiulcer activity of aqueous extract of fruits of Momordica cymbalaria Hook f. Initially the aqueous extract of M. cymbalaria was subjected to acute oral toxicity study according to the Organisation for Economic Co-operation and Development (OECD) guidelines, based on which, 500 mg/kg dose of aqueous extract was selected for the study. The animals were pretreated before inducing ulcer. For inducing ulcer in the rats, 80% ethanol was used. Various parameters such as area of gastric lesion, nonprotein sulfhydryls (NP-SH) concentration, gastric wall mucus concentration, total acidity and volume of gastric content; and histopathological parameters like hemorrhage, edema, erosion, ulceration were studied in the control group and pretreated groups with aqueous extract of fruits of Momordica cymbalaria (500 mg/kg) and standard drug lanzoprazole (30 mg/kg). Pretreatment with aqueous extract of M. cymbalaria fruits showed significant (P < 0.05) decrease in the total acidity and ulcer index. Improvements in all histopathological parameters were noticed in the M. cymbalaria-treated group. It also showed significant decrease in gastric lesion and NP-SH and gastric wall mucus concentrations in the M. cymbalaria-treated group. Overall the aqueous extract of M. cymbalaria fruits was shown to possess significant (P < 0.05) antiulcer property in rats. The polyphenols like quercetin reported from the plant may attribute to the antiulcer property of the extract.
