Abstract:
Objective: To study the liposoluble constituents from the rhizome of Dioscoreae hypoglaucae. Methods: The chemical constituents were isolated and purified by chromatographys and the structures were analyzed and identified by physicochemical properties and spectroscopic data. Results: Thirteen compounds including three diarylheptonoids and other types were isolated from the rhizome of D. hypoglaucae, and their structures were elucidated as tsaokoarylone (1), 1,7-bis (4-hydroxyphenyl)-4,6-heptabien-3-one (2), 1,7-bis (4-hydroxyp henyl)-1,4,6-heptatrien-3-one (3), emodin (4), 7-hydroxy-2,6-dimethoxy-1,4- phenanthrenequinone (5), diosgenin (6), ruscogenin (7), kaempferol (8), 3S-6,8-dyhydroxy-3-phenyl-3,4-dihydroisocoumarins (9), 5-hydroxymethylfurfural (10), β-sitosterol (11), stigmasterol (12), and hexacosanoic acid (13). Conclusion: Compounds 4, 5, 7, 8, 12 and 13 are isolated from the rhizome of D. hypoglaucae for the first time. Compounds 1 and 10 are isolated from the species of Dioscoreaceae for the first time.
