摘要Objective: To assess the anti-diabetic and antidiarrheal activity of methanolic extract of Phyllanthus reticulates (P. reticulates) leaves in an animal model. Methods: Phytochemical screening of methanolic extract of P. reticulatus leaves has been performed. Antidiabetic activity have been done by OGTT, normoglycemic hyperglycemia and alloxan induced diabetic mice. Plant extracts (150 mg/kg and 300 mg/kg, b.w.) were administered orally in fasting glucose loaded mice with regard to normal control and in alloxan induced (110 mg/kg body weight i.p.) diabetic mice in comparison with reference drug Metformin hydrochloride (100 mg/kg) during 7 day test period. Antidiarrheal test was conducted by castor oil and magnesium sulfate. Results:Findings confirmed that the continuous post-treatment for 7 days with both extracts showed significant (P<0.05) hypoglycemic activity in OGTT, normoglycemic and alloxan induced mouse models. Castor oil and Magnesium sulfate induced diarrheal test of the extract (200 and 400 mg/kg) has given significant effect in compairing to control diarrheal group. Conclusion:Methanolic extract of P. reticulatus leaves have shown significant antidiabetic and antidiarrheal properties.
