我国鬼臼类植物资源的研究

本文较为系统地整理了我国鬼臼类的原植物,它们是八角莲属(Dysosma)、桃儿七属(Podophyllum)和山荷叶属(Diphylleia)等3属共10种。并对鬼臼的原植物进行本草考证,指出鬼臼应系八角莲属植物。同时对上述3个属的8个种的样品进行了成分定性,证明这些植物均含有鬼臼脂素及其他木脂素成分。另外还利用鬼臼脂素的分子中含有次甲二氧基的特点,用比色法测定了样品中的鬼臼脂素的含量:八角莲属6个种鬼臼脂素的含量不超过1%,桃儿七为2.7～4.2%,南方山荷叶为4.9%。

A STUDY ON THE RESOURCES OF CHINESE PODOPHYLLIN PLANTS

Of all the podophyllin plants, which include 3 genera and about 12 species, the majority (3 genera and about 10 species) has been found in China. All the Chinese species Were show to contain lignans and podophyllotoxin. The content of podophyllotoxin were found to be 2.7～4.2% in Podophyllum emodi, 4.9% in Diphylleia sinensis and less than 1% in 6 species of Dysosma.
