将商陆Phytolacca acinosa Roxb.成熟浆果阴干粉碎后,用90%乙醇提取,提取液浓缩、冷却、过滤,滤液除去溶剂后用苯提取,苯不溶部位溶于乙醇后用硅胶柱层析,以苯-乙酸乙酯和乙酸乙酯-甲醇梯度洗脱,TLC 检测。用苯-乙酸乙酯(7∶3)洗脱得到的第7部位进一步经硅胶柱层析,得到 acinospesi- The Phytolacca acinosa Roxb. Mature berries were dried and crushed and then extracted with 90% ethanol. The extract was concentrated, cooled and filtered. The solvent was removed after the filtrate was extracted with benzene, and the benzene-insoluble fraction was dissolved in ethanol and then subjected to silica gel column chromatography. - Ethyl acetate and ethyl acetate-methanol gradient elution, TLC detection. The 7th position eluted with benzene-ethyl acetate (7:3) was further subjected to silica gel column chromatography to obtain acinospesi-
