Study on Optimizing Extraction Process for Ginsenoside With Orthogonal Design / 中国药房

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_TSThe amount and concentration of alcohol and extraction time showed significant influence on extract obtained.CONCLUSI_ONThe optimal extraction process is as followsadding 75% alcohol into crude ginseng(6∶1 in weight) and extracting 6 times for 45 min each extraction.
