Study on Optimizing Extraction Process for Ginsenoside With Orthogonal Design

Xie Yuqiong

Abstract

OBJECTIVE:To study the extraction process of ginsenoside.METHODS:The optimal extraction process was selected with the orthogonal design.The content of ginsenoside in ginseng was determined by UV-Spectrophotometry.RESUL_TS:The amount and concentration of alcohol and extraction time showed significant influence on extract obtained.CONCLUSI_ON:The optimal extraction process is as follows:adding 75% alcohol into crude ginseng(6∶1 in weight) and extracting 6 times for 45 min each extraction.
