Extraction of Resveratrol from Circassian Fruit by Enzyme Assisted Extraction
The dry powder of circassian fruit was used as test material,to study the enzymatic assisted extraction process of resveratrol in it using single-factor and orthogonal experiment optimization,and the content of resverstrol was tested by colorimetric method.The results showed that the suitable extraction conditions for enzyme assisted extraction were pH 4.75,temperature 50 ℃,enzymolysis time 120 min,the additive amount of cellulasewas120 mg/g.In this optimal condition,the yield of resveratrol could reach 114.37 μg/g,which was 1.72 times as much as rthanol extraction method only.
