THE STUDY OF EXTRACTION CONDITIONS AND THE EFFECT OF REDUCING BLODD SUGER AND ANTIOXIDANT ACTIVITIES OF GLUE EXTRACTED FROM BASIL

Abstract

Basil (Ocimum basilicum) is widely used as an herb. Ability of resistance, inhibiting the starch hydrolytic enzyme of the glue extracted from basil had been determined. The results showed that, when changing extraction conditions, different total phenolic content would be obtained. Optimal conditions (with 1/100 sample solvent ratio, the duration of 35 min at the temperature of 55⁰c), obtaining the highest phenolic content is 43.6 ± 0.03 mg GAE / g dry matter. Ability of inhibiting the activity of free radical DPPH is 38.2 ± 1.1%. Extracted liquid from basil has ability of inhibiting a-amylase and a-glucosidase equivalent to 45.8 ± 0.82%, 22.7 ± 1.1%. From this result, it can be seen that the liquid extracted from basil contains high antioxidant phenolic substances when appropriate extraction conditions are used
