Open publisher page 0 citations

Abstract

The optimal conditions of flavonoids extraction from chestnut were studied. The effects of five factors including alcohol content,extraction period,extraction time,temperature,and the ratio of raw materials and solution on extraction amount were investigated. The best technical conditions for flavonoids extraction were obtained through orthogonal experiments based on single factor as following: extracting with 60 % alcohol,temperature at 70 ℃ extracting 30 min,ration of raw materials and solution was 1:9. Under the optimized condition,the extraction amount of flavonoids from chestnut was 137.7 mg/g.
