Abstract: Seven free spirostane sapogenins (A-G) and 1β,2β,3β,4β,5β,7α-hexahydroxyspirost-25(27)-en-6-one were isolated by column chromatography from the acetyl acetate extract of the root of Tupistra aurantiaca Wall et Backer. Two of the them were identified as 3-epiruscogenin(1) and 3-epi-neorus -cogenin (2) respectively. Compound C,D and E are new compound,they were nmaed as ranmogenin A,B and C. Their structures have suggested as (3),(4) and (5) respectively,based on analyses using IR,MS,1H NMR 13 C NMR.
Key words: Tupistra aurantiaca
