摘要: 研究了不同溶剂浸提与其他提取条件对葡萄籽原花色素提取收率的影响,确定70%丙酮或70%乙醇的提取溶剂,1:4的料液比,室温下8~10 h的提取条件。使用乙酸乙酯先萃取然后用丙酮的原花色素分离技术,表明前者处理原花色素收率为14.4%~31.6%,产物纯度32%以上,后者处理原花色素收率54.3%~63.5%,产物纯度27.9%以上。

Abstract: The conditions of extracting proanthocyanidins from grape seeds were studied in this paper. The following conditionswere established: 70% acetone or 70% ethanol, the ratio of the solid material to solution 1:4 and the extracting time 8~10hat room temperature. The proanthocyanidins by acetone fractionated after the extraction of ethyl acetate. The yield of ethylacetate extraction was 14.4%~31.6%, with a purity over 32% while the yield of acetone ffrachionation was 54.3%~63.5%with a purity over 27.9% with a purity.
Key words: Proanthocyanidins , Grape seed , Ectraction and fractionation
