Abstract:

本文采用固定功率超声辅助碱液降低白果中银杏酚酸的含量,建立一种降低白果粉中银杏酚酸类致敏物质的新工艺。作者探究了萃取时间、萃取温度、碱液中甘油添加量的单因素影响,并进一步通过正交法优选出工艺参数:超声萃取时间40 min、萃取温度40℃、碱液中甘油添加量15‰,此条件下银杏酚酸含量为1.35 μg/ml,符合国家药典2020版标准。
In this paper, fixed power ultrasound assisting alkaline solution was used to reduce the content of ginkgolic acid in Ginkgo biloba and establish a new process for reducing the allergenic substances of ginkgolic acid in Ginkgo biloba powder. The authors explored the single-factor effects of extraction time, extraction temperature, and the amount of glycerol added to the alkaline solution, and further optimized the process parameters through orthogonal design: extraction time of 40 minutes, ex-traction temperature of 40?C and the amount of glycerol added to the alkaline solution of 15‰. Under this condition, the ginkgolic acid content is 1.35 μg/ml, which meets the standard of the National Pharmacopoeia 2020 edition.
