Three kinds of pregnane derivatives G_5,G_6,and G_7 were isolated from the aerial parts of Dioscorea tenuipes FRANCH. et SAVAT. They were characterized as 2β, 3α, 4β-trihydroxy-5β-pregn-16-en-20-one (IV) and its 2-(VII) and 4-monoacetates (VIII), respectively, which are corresponding to coexisting diotigenin (I) and its monoacetates (II and III).
