摘要
目的 :研究人参皂苷的提取工艺。方法 :采用正交试验法进行优选 ,紫外分光光度法测定人参中人参皂苷含量。结果 :乙醇用量、乙醇浓度、提取时间等对人参皂苷的提取有显著影响。结论 :最佳提取工艺为药材加6倍量70 %乙醇 ,提取6次 ,每次45min。
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.
