Abstract
Twenty-two samples of cultivated Dioscorea Zingiberensis Wright are determined. The results show that the diosgenin in the plant samples are various according to the growing periods and sexes. The content of diosgenin in male plant is higher than that in female. The longer the growing period of the plant is the more diosgenin there is . The content in male plant gathered in October is higher than in any other months, The melting range of diosgenin extracted by means of general method from all the samples is nearly the same(196～200℃). It can be concluded that the 3-year-old cultivated D.zingiberensis Wright can be applied to diosgenin producing industry.$$$$
