摘要: 本文以脱脂沙棘籽为原料,乙醇为提取液,通过提取温度、提取时间、脱脂时间、料液比、酒精浓度、pH值6个单因素实验,在中心组合实验基础上,采用响应面分析法,确定沙棘籽中原花色素的最优提取条件。研究结果表明,在提取温度21℃、pH5.1、酒精浓度65%时,沙棘籽中原花色素的提取率达5.84%(以脱脂沙棘干重计),粗品纯度达39.18%。

Abstract: Technology of extracting proanthocynidins from sea buckthorn seed were studied. The dried defatted sea buckthorn seed was used as raw material. After investigating the single effect factor on proanthocyanidins extraction, the optimum factors were obtained. The central composite design and corresponding response surface analysis were used to obtain the optimal parameters of processing. The optimum conditions of extraction were as follows: the rate of solution phase to solid phase 10: 1, the temperature 21℃, extraction time 90min, pH value 5.1, and the concentration of ethanol 65%. The extraction yield was 5.84% on the dry weight basis of defatted sea buckthorn seed powder with the product purity as 39.18%.
