摘要
Plants have been shown to possess a great potential to benefit mankind. Extracts from plants that have antiglycation and antioxidation abilities can be of great therapeutic value in reducing complication of diabetes and slowing down aging. Advanced glycation end-products (AGE's) formation due to non-enzymatic glycation and oxidative stress has been demonstrated in the pathogenesis of diabetic complications and aging processes. In this study we investigated the antiglycation and antioxidation potential of methanolic extracts of Berberis lyceum and Terminalia chebula. Results indicated that the methanolic extract of B. lyceum had more antiglycation ability with a Minimum inhibitory concentration (MIC50) of 123 mu g/mL as compared to the MIC50 of 110 mu g/ml of T. chebula. While the results of antioxidation assay showed that T chebula has more antioxidation potential than B. lyceum. T. chebula had 46.55, 35.01 and 32.81% antioxidation potential at 0.5 mg, 0.25 mg and 0.125 mg respectively as compared to the 16.53, 16.09 and 15.10% oxidation inhibition at same mass values by B. lycium.
