Sinopodophyllum hexandrum(Royle)Ying is a herbaceous and rhizomatous species of great medicinal importance that is endangered in China. Several lignans have been isolated from its rhizomes,the most important being podophyllotoxin which has cytotoxic and antitumour properties and has been used in the treatment of certain forms of cancer. Recently,the frequency of this species in nature has declined considerably because of recklessly exploitation to meet the ever-increasing demand of pharmaceutical companies. In the natural habitat,seed germination and seedling establishment are very poor. Because the species is already endangered,and exploitation of its underground parts continues to exceed the rate of natural regeneration,it needs immediate attention for conservation. Studies of its biology and genetics are important for successful development of conservation strategies. This paper described the biological characters of Sinopodophyllum hexandrum,including morphology,distribution,systematics,development and morphogenesis,reproductive biology,ecology and population biology,phytochemistry,vitro culture and endophytic fungi,genetics and molecular biology, and presented future prospect and conservation strategies for this important medicinal species.
