目的:探索闪式提取-大孔树脂吸附分离山银花中绿原酸的最优工艺参数.方法:以绿原酸的转移率为评价指标,采用响应面试验设计,对闪式提取山银花中绿原酸的主要工艺参数进行优化.以绿原酸转移率及产品纯度为评价指标,以山银花药材水提液为上样液,采用单因素试验设计,对大孔树脂吸附分离绿原酸工艺中的主要工艺参数进行优化.结果: 闪式提取-大孔树脂吸附分离山银花中绿原酸的最优工艺条件为:料液比为1: 23,提取时间为4. 7 min,转数为6 000 r·min-1,大孔树脂类型为ADS-7,生药量与大孔树脂重量之比为1: 5,上样液流速为1 BV·h-1,先用1 BV的水以1 BV·h-1的流速洗脱,再用6 BV的20%乙醇以2 BV·h-1的流...

Objective: To explore the optimal extraction process by a blitzkrieg extractor and the adsorption separation by macro-porous resin for chlorogenic acid in Lonicera macranthoides. Methods: The transfer rate of chlorogenic acid was used as the main as-sessment index, the response surface test was adopted to optimize the main influencing factors in the extraction process by a blitzkrieg extractor for chlorogenic acid in Lonicera macranthoides. The transfer rate and the product purity of chlorogenic acid were used as the main assessment indices, th...
