Abstract
The research was carried out to optimize the extraction conditions of phenolic antioxidant from the leaves of
Polyalthia longifolia. It was optimized by using L16 orthogonal design of experiment. The effect of single factors
such as shaking speed, extraction time, modifier concentration and material ratio on the extraction of the phenolic
antioxidant was investigated. The maximum phenolic antioxidant content was obtained under optimum
conditions of shaking speed at 200 rpm, shaking time 10 min with material ratio of 1:10 and 80% of ethanol.
