[Study on steroidal compounds from Dioscorea zingiberensis].
OBJECTIVE: To study the chemical constituents of Dioscorea zingiberensis. METHOD: Manifold chromatography methods were used to separate the chemical constituents, and the chemical stuctures were determined by spectral analyses. RESULT: 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. CONCLUSION: Deltonin and protodeltonin were isolated from this plant for the first time.
