Introduction: Nymphaea stellata Willd. (Nymphaeaceae) is traditionally used for the treatment of diabetes. Alcohol extract of N. stellata leaves has been reported for hypoglycaemic activity. Objective: The aim of this study was to further investigate the different methanol fractions of N. stellata leaves for anti-diabetic activity and anti-platelet aggregation activity. Methods: Methanol extract was fractioned in to unsaponified petroleum ether fraction of methanol extract (UPFME), chloroform fraction of methanol extract (CFME) and residual fraction of methanol extract (RFME). All fractions were evaluated for in vivo anti-diabetic activity (STZ-NAD-induced rat model), in vitro anti-diabetic activity (PTP1B inhibition study) and anti-platelet aggregation activity. Results: UPFME showed significant changes in all studied parameters, compared to the diabetic control. UPFME also showed an IC50 value of 19.30±1.1 mg/ml and 13.11±0.7 μg/ml in PTP1B inhibition study and anti-platelet aggregation study, respectively. Conclusion: The study indicates that UPFME of N. stellata leaves exhibit anti-diabetic and anti-platelet aggregation activity.
