桃儿七(Podophyllum emodi Wall.Var Chininsis Sprague)根茎中分离得到的鬼臼脂素是一种具有很大毒性的抗癌天然产物,是抗癌新药VP16-213和VM26等的半合成原料。 早期文献报道,鬼臼脂素定量分析用薄层色谱—洗脱分光光度法,该法步骤多、费时、斑点定位困难,因而误差较大; Podophyllum emodi Wall.Var Chininsis Sprague rhizome isolated podophyllotoxin is a highly toxic natural product of anti-cancer, anti-cancer drugs VP16-213 and VM26 semi-synthetic raw materials. Earlier literature reported that podophyllotoxin quantitative analysis by thin-layer chromatography - elution spectrophotometry, the method of multi-step, time-consuming, spot positioning difficulties, and thus greater error;
