Abstract: Salacia chinensis L. (Saptrangi) belongs to the family Hippocrateaceae. The plant extracts have been evaluated for number of activities like anti-hyperlipidemic, anti-inflammatory, cardiotonic, sedative and neuromuscular. In traditional medicine, this plant has been used in the treatment of diabetes. In the present study, methanolic extracts of leaf, stem and root of Salacia chinensis were tested for antihyperglycaemic activities in alloxan induced diabetic mice. Glibenclamide (500 μg kg-1) was used as the reference drug. Results showed that the methanolic extracts of leaf, stem and root exhibited antihyperglycaemic effect. Methanolic extracts of root exhibited better activity followed by stem and leaf which were equally effective.
