【摘要】 <正> 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;更多还原

【Abstract】 Tke nine compounds in lignins have been separated by high performance liquid chroma-tography. Analytical conditions of HPLC are as follows: column, Partisil-5; mobile phase, n-hexane-dichloromethane-methanol (90:10=B). The effects of methanol and dichloromethane on the retention value have been discussed ia the paper. The coatent of the commodity podophyllotoxin has also been determined.更多还原
