摘要: 以茶籽为原料,以茶籽皂苷提取得率为考察指标,系统研究了乙醇浓度、微波强度、微波辅助提取时间、料液比等因素对微波辅助提取茶籽皂苷的得率影响,优化筛选了微波辅助提取茶籽皂苷的最优工艺技术及其参数。结果表明,采用乙醇体积分数60%、微波功率539βW、微波辅助提取时间7βmin、料液比1︰50的工艺参数进行微波辅助提取茶籽皂苷,皂苷得率可达18.56%。与常规水提取、乙醇提取相比,微波辅助提取的茶籽皂苷得率分别提高了6.84%、6.22%,且提取时间大为缩短。

Abstract: By using tea seed as test material, the effect on ethanol concentration, microwave power, extraction time, solid-liquid ratio and other factors on the extracting yield of tea seed saponin were studied in order to comprehensive exploitation and utilization of tea seed saponins resources, and the optimum technology parameter of microwave assisted extraction of tea seed saponin were obtained. The result showed that extraction parameters of saponin from tea seed by ethanol volume fraction 60%, microwave power 539βW, auxiliary extraction time 7βmin, solid-liquid 1︰50, and the tea saponin yield reached 18.56%, which increased 6.84%, and 6.22% respectively compared to the conventional water extraction method and ethanol extraction method. Besides, the extracting time was shorten signicantly.
