| Abstract: |
| OBJECTIVE To study in vitro antioxidant activity and α-glucosidase inhibitions of ethanol extract from leaves of Rosae roxburghii Tratt. METHODS Antioxidant and free radical scavenging activities of ethanol extract of Rosae roxburghii leaves were determined by DPPH and ABTS radical scavenging assay. α-Glucosidase inhibitions was determined by α-glucosidase inhibitory assayed in vitro. RESULTS The ethanol extract of Rosae roxburghii leaves showed significant DPPH and ABTS radical scavenging activities. The extract also exhibited a significant α-glucosidase inhibitory effect in vitro. CONCLUSION Rosae roxburghii leaves show significant antioxidant and α-glucosidase inhibitory activities. |
