用RAPD法对铁钱莲属7种生药的鉴定[即山棉花ClematischrysocomaFr.、三叶五香血藤C.fasciculifoliaFr.、小九头狮子草C.ranumculoidesFr.、小木通C.armandiiFr.、红叶铁线莲C.rubifoliaC.H.Wright、红钉耙藤C.brevicaudataDC.、和铁线莲C.floridaThunb.]。结果表明RAPD种间差异明显而同种不同产地差异不明显。

Identification of seven species of Clematis L.（C. chrysocoma Fr.,C. armasedii Fr.,C. fasciculifolia Fr.，C. ranunculoides Fr.,C. rubifolia C. H. Wright,C. jZorida Thunb. and C. brevicaudata DC.）was studied by RAPD analysis. Results showed that the differences of RAPD between different species were significant,butnonsignificant between same species obtained from different localities.
