摘要
本文对枸杞类胡萝卜素的浸提条件进行了研究,得到的最佳参数是:浸提液为石油醚-丙酮(1:3,v/v)混合溶剂,料液比为90(g/mL),在常温下分3次浸提,总浸提时间为1.5h。枸杞总类胡萝卜素的含量为552.57mg/kg。洗脱剂选择正己烷:丙酮=90:10(v/v),吸附剂选择为氧化镁:硅藻土=1:2(w/w),薄层展开剂选择为石油醚-丙酮=17:4,此条件下对枸杞色素提取液。
In this paper, the carotenoids extraction conditions were studied. We can use petroleum ether and acetone（1：3,v）as extract solvent, and select the solid-liquid ratio of 90 （g/mL）. Then we extract lycii carotenoids three times spending 1.5h under this condition. We select hexane acetone（90：10,v）as eluent, magnesium oxide diatomite（1：2,w/w）as adsorbent. Besides, we select petroleum ether and acetone as the developing solvent of TLC. Under this condition, the separation effect for pigment of Fructus Lycii extract and total carotenoid sample is superior.
