anti-diarrheal and hypoglycemic activities of methanol extract of calamus rotang l. seed in rat

background and objectives: calamus rotang is used in traditional medicine. regarding the previous phytochemical screening of methanol extract of calamus rotang l. fruits (mcr), this study was performed to find out the antidiarrheal and hypoglycemic effects of the experimented extract in rodents. methods: castor oil induced diarrheal test was followed for screening anti-diarrheal effect of mcr. in order to explore the hypoglycemic effect, normoglycemic study, oral glucose tolerance test (ogtt) and study on alloxan-induced diabetic rats were carried out. in each experiment, 250 and 500 mg/kg body weight doses of mcr were used. results: the plant extract showed pronounced, significant (p < 0.01) antidiarrheal activity on both doses in a dose-dependent manner. at higher dose, mcr showed almost similar antidiarrheal effect as standard loperamide.  in case of normoglycemic test, a single dose of mcr caused a significant (p
