Isolation and Evaluation of Cytotoxic, Anti-Inflammatory, Anti-Ulcer Activity of Methanolic Extract of Ceriops decandra leaves

The current study was undertaken to provide scientific validation for the traditional medicinal applications of Ceriops decandra leaves in treating gastrointestinal disorders and inflammation. Additionally, the study aimed to isolate a pure component from the extracted leaves for further analysis. Lupeol was extracted from the crude methanolic extract of Ceriops decandra leaves by column chromatography as part of a phytochemical inquiry. Its structure was determined using 1H and 13C NMR spectroscopy. In order to assess the cytotoxicity, the unrefined methanolic extract was divided into two fractions: a petroleum fraction and an aqueous fraction, employing the modified Kupchan method. The brine shrimp lethality test revealed that both the aqueous and petroleum ether fractions had significant cytotoxic activity, with LC50 values of 1.93 µg/l and 2.04 µg/l, respectively. These values were compared to the LC50 value of the standard Vincristine Sulphate, which was found to be 0.02 µg/l. The results of the anti-inflammatory trial demonstrated that the administration of the extract at doses of 250mg/kg and 500mg/kg resulted in protection rates of 62.5% and 87.5%, respectively, as compared to the carrageenan control group after 3 hours post-injection. It is worth noting that Ibuprofen exhibited a higher level of protection, with a rate of 91.7%. In the context of ethanol-induced stomach ulcer, the administration of extracts at doses of 250 mg/kg and 500 mg/kg resulted in 45.5% and 59.1% protection against gastric ulcer, respectively. These findings were compared to the protective effect of Omeprazole, which demonstrated 63.6% protection and served as the standard reference. The findings suggest that the methanolic leaf extract of Ceriops decandra possesses robust cytotoxic and potent anti-inflammatory and anti-ulcer properties. These results provide support for the traditional application of this extract in the management of gastrointestinal diseases, inflammation, and cancer.

Gastroprotective Activity of Aerial Leaves of Allium cepa

The present study was performed to evaluate the Antiulcer activity of Methanolic extract of Allium cepa leaves (MEAC) in Albino rats. Antiulcer activity of MEAC was investigated by using Ethanol induced gastric mucosal damage and Pylorous ligated gastric ulcers. Evaluation was done on both models comparing with reference standard Omeprazole (20mg/kg). The parameters taken to assess anti-ulcer for pylorus ligation method were volume gastric secretion, pH, free acidity, total acidity and ulcer index. In vivo studies were carried on the plant extract and results were found that protection of the Methanolic extract of Allium cepa leaves against characteristic lesions may be due to both reduction in gastric acid secretion and gastric cycloprotein and this may be due to the presence of Flavanoids. In this study we observed that, Methanolic extract of leaves of Allium cepa (MEAC) provides significant antiulcer activity against gastric ulcers in rats. The result of MEAC showed significant reduction in the ulcer index, when compared to control. The antiulcer activity extract may be attributed to their flavanoids content and antioxidant property. These findings indicate that MEAC display potential antiulcerogenic activity.

Evaluation of the Antiulcer Activity of Methanolic Extract and Solvent Fractions of the Leaves of Calpurnia aurea (Ait.) Benth. (Fabaceae) in Rats.

Introduction In Ethiopia, traditionally, the leaves of Calpurnia aurea have been utilized to treat peptic ulcer disease. Therefore, the objective of the present study was to examine the antiulcer activity of Calpurnia aurea hydromethanolic leaf extract and solvent fractions in rats. Methods The ulcer-healing potential of the crude test extract was assessed in rats by adopting pyloric ligation-, acidified ethanol-, and acetic acid-induced ulcer methods; while, in solvent fractions, the acidified ethanol-induced ulcer model was used. In all models, three serial test doses (100, 200, and 400 mg/kg) were given and the antiulcer activity was investigated. Standard drugs like sucralfate (100 mg/kg), omeprazole (20 mg/kg), and cimetidine (100 mg/kg) have been used as a positive control; whereas distilled water (10 mL/kg) was used as the negative control. Parameters like ulcer index, total acidity, pH, gastric volume, and gastric mucin level were all measured. Results In an acute toxicity study, the test extract at the limit test dose (2 g/kg) was safe following a single dose administration. In pyloric ligation-induced ulcers, the plant extract at 200 and 400 mg/kg significantly reduced the ulcer index, the volume of stomach secretion, and total acidity while raising gastric pH and mucus content (P < 0.05). Likewise, in the acidified ethanol- and acetic acid-induced ulcer models, the extract at both test doses (200 and 400 mg/kg) also displayed a substantial reduction (P < 0.05) in ulcer index. Among the fractions, the ethyl acetate fraction revealed remarkable cytoprotective activity at all test doses and the aqueous fraction at 400 mg/kg (P < 0.05). In contrast, the effect of chloroform fraction was found to be negligible. The peak ulcer inhibition was noted at 400 mg/kg of ethyl acetate fraction (52.4%). Conclusion The study showed that the crude extract and solvent fractions possess remarkable antiulcer activity.

Evaluation of anti-inflammatory and gastric anti-ulcer activity of Phyllanthus niruri L. (Euphorbiaceae) leaves in experimental rats

BackgroundThe medicinal plants signify a massive basin of potential phytoconstituents that could be valuable as a substitute to allopathic drugs or considered as an analogue in drug development. Phyllanthus niruri L. (Euphorbiaceae) is generally used in traditional medicine to treat ulcer and inflammation. In this project we investigated the methanolic extract of leaves of Phyllanthus niruri for anti-inflammatory and anti-ulcer activity.MethodsThe anti-inflammatory activity of methanol extract of Phyllanthus niruri leaves was evaluated at the doses of 100, 200 and 400 mg/kg, p.o. while using ibuprofen (20 mg/kg, p.o) as the standard drug. The animals used were Swiss albino rats. Inflammation was induced by injecting 0.1 ml carrageenan (1% w/v) into the left hind paw. Paw tissues from the different groups were examined for inflammatory cell infiltration. On the other hand, antiulcer activity of methanolic extract of P. niruri leaves at the doses of 100, 200 and 400 mg/kg, p.o. were examined against ethanol-acid induced gastric mucosal injury in the Swiss albino rats - keeping omeprazole (20 mg/kg, p.o.) as reference. The rats were dissected and the stomachs were macroscopically examined to identify hemorrhagic lesions in the glandular mucosa.ResultsP. niruri significantly (p < 0.01) decreased carrageenan-induced paw edema; it exhibited a reduction of 46.80%, 55.32% and 69.14% at doses of 100, 200 and 400 mg/kg, respectively. These findings were further supported by the histological study. The methanolic extract also disclosed good protective effect against ethanol-acid induced gastric mucosal injury in the rats. Administration of the extract’s doses (100, 200 and 400 mg/kg) demonstrated a significant (p < 0.01) reduction in the ethanol- acid induced gastric erosion in all the experimental groups when compared to the control. The methanolic extract at the higher dose (400 mg/kg) resulted in better inhibition of ethanol-acid induced gastric ulcer as compare to omeprazole (20 mg/kg). Histological studies of the gastric wall revealed that toxic control rats revealed mucosal degeneration, ulceration and migration of numerous inflammatory cells throughout the section. On the other hand, MEPN treatment groups showed significant regeneration of mucosal layer and significantly prevented the formation of hemorrhage and edema.ConclusionsThe investigation suggests that methanolic extract of P. niruri leaf possess anti-inflammatory activity and promotes ulcer protection as ascertained by regeneration of mucosal layer and substantial prevention of the formation of hemorrhage and edema.

Protective effects of edible Rhus tripartita (Ucria) stem extract against ethanol-induced gastric ulcer in rats

Rhus tripartita is a plant which is traditionally used for the treatment of ulcer and diarrhea in Tunisia. The aim of the study is to evaluate the antiulcer activity of methanol extract of Rhus tripartita stem (RSE).The phytochemical analysis of RSE was performed. Fasted rats treated with 80% ethanol (0.5mL) to induce gastric ulcer, were pretreated orally with RSE at different doses (200, 400 and 800mg/kg body weight (BW)) and ranitidine (100mg/kg) and distilled water were used as a positive and negative control respectively.The results showed that the pre-treatment with RSE decreased significantly the ethanol gastric ulcer index value and preserved the integrity of the gastric mucosa by preventing the mucosal ulceration caused by ethanol. The RSE prevented alcohol-induced decrease in stomach antioxidant enzyme activities such as catalase, glutathione peroxidase and superoxide dismutase. Total reduced glutathione and malondialdehyde tissue contents were also reversed in RSE-pretreated rats when compared with the negative control group.
