[Study on steroidal compounds from Dioscorea zingiberensis].
OBJECTIVE
To study the chemical constituents of Dioscorea zingiberensis.


METHODS
Manifold chromatography methods were used to separate the chemical constituents, and the chemical stuctures were determined by spectral analyses.


RESULTS
6 compounds were isolated from Dioscorea zingiberensis and identified as deltonin, protodeltonin, zingiberensis newsaponin, dioscin, 3-O-[beta-D-glucopyranosyl(1 --> 4)]-beta-D-glucopyranosyl-diosgenin, diosgenin.


CONCLUSIONS
Deltonin and protodeltonin were isolated from this plant for the first time.
