title: [Determination of podophyllotoxin lignans in Dysosma and its allied plants].
abstract: The existence of podophyllotoxin lignans in Dysosma versipellis and its allied plants was analyzed by twice developing TLC, and the content by chromotropic-colorimetric assay. The results showed that podophyllotoxin lignans exist in the rhizoma, radix, stem and leaf of Dysosma versipellis and its allied plants. The total lignans content is 2%-7%, and there is a big variation between different species. The total lignans content of Dysosma versipellis is related to the habitat.
