This study investigated the gastroprotective effect of Ayapana triplinervis leaves against indomethacin‐induced gastric ulcer in male albino rat. Gastric ulceration was developed by single oral dose of indomethacin (30 mg/kg). Experimental rats were pretreated with omeprazole (positive control 20 mg/kg), hydromethanolic extract of A. triplinervis (200 mg/kg) for 28 days just before the indomethacin treatment. Free acidity, total acidity, pepsin activity and gastric volume, gastric pH, tumor necrosis factor‐alpha (TNF‐α), interleukin‐6 (IL‐6) in stomach and serum prostaglandin E2 levels were assessed in control, ulcerated group and A. triplinervis pretreated groups. Oxidative stress biomarkers, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in serum also evaluated. All the parameters were deviated from control in indomethacin‐treated group but significantly protected in A. triplinervis–pretreated group. The active ingredient(s) present in the A. triplinervis have antioxidant and gastroprotective properties that prevent the indomethacin‐induced gastric ulcer. Practical applications A. triplinervis has been widely consumed from earlier time as traditional medicine for the treatment of gastric problem and gastric ulcer in India. This is the first report that hydromethanolic extract of A. triplinervis has potent therapeutic properties against gastric ulcer. This work will provide a clue to the pharmaceutical industry to develop an effective gastroprotective agent.

An in vitro spermicidal effect of aqua-methanolic (2:3) extract of Thevetia peruviana leaves on human spermatozoa was evaluated in a dose-dependent manner (20, 40, 80 and 160 mg/ml) at a 1:1 ratio. Sperm motility, viability, hypo-osmotic swelling (HOS) and acrosomal status and function tests were performed immediately (20 s), and after 5 and 10 min of exposure of the spermatozoa to the extract of Thevetia peruviana
