摘要
Abstract
Dihydroquercetin was extracted from larch by water. The influence of three conditions on extraction yield was investigated. The optimum extracting condition was obtained through the orthogonal experiment, and the result was as follow: extraction temperature was 90℃ , solid - liquid ratio was 1 : 12 (g/mL), extraction time was 40min, extraction three times. Three kinds of purification methods including alcohol precipitation, macroporous resin and poly-amide absorption were used to purify dihydroquercetin. A comparative study showed that all three methods have certain purification effect. Polyamide absorption was the best, while alcohol precipitation combined with macroporous resin absorption is a new method for purification of dihydromyricetin.关键词
