Summary of article contents:

Introduction

Bryophyllum pinnatum is a medicinal plant widely recognized for its traditional use in various cultures, including India, Africa, Tropical America, and China, to treat a range of ailments. The plant contains a multitude of phytoconstituents such as flavonoids, terpenoids, alkaloids, and phenolic compounds, which are thought to contribute to its therapeutic effects. The present study aims to evaluate the gastroprotective activity of aqueous extracts and mucilage derived from the whole plant of B. pinnatum against gastric ulcers induced by ethanol in rat models. This research is significant as peptic ulcers remain a prevalent gastrointestinal issue, and there exists a need for safer herbal alternatives to the conventional antiulcer medications, which may pose adverse side effects.

Gastroprotective Activity of Bryophyllum pinnatum

The study demonstrated that both the aqueous extract of B. pinnatum (AEBP) and the isolated mucilage (MUC) exhibited a significant reduction in ethanol-induced gastric ulcers in rats. Specifically, the administration of AEBP at doses of 750 mg/kg and MUC at 500 mg/kg resulted in notable decreases in ulcer incidence, gastric volume, free acidity, and overall ulcerative index compared to the control group. The protective index for AEBP was 72.69%, while MUC showed a protection index of 69.65%. Histopathological examinations further confirmed these findings, revealing that treated groups experienced reduced mucosal damage and inflammation, indicating a regenerative effect on gastric tissue. This efficacy was comparable to the standard drug rabeprazole, thereby illustrating the potential of B. pinnatum extracts for therapeutic use.

Conclusion

The study concludes that extracts from Bryophyllum pinnatum possess significant gastroprotective properties, effectively mitigating ethanol-induced gastric damage in a dose-dependent manner. The findings underscore the therapeutic potential of both AEBP and MUC in preventing gastric ulceration, with the extract exhibiting the most profound effects at a dosage of 750 mg/kg. Given its efficacy, B. pinnatum could serve as a promising candidate for further clinical research aimed at developing herbal-based treatments for gastric ulcers. Additionally, the study encourages the exploration of natural remedies as alternatives to conventional drugs in the management of gastrointestinal disorders.
