Abstract:
Three new eudesmanoids have been isolated from Sphaeranthus indicus and their structures were established as 11alpha,13-dihydro-3alpha,7alpha-dihydroxy-4,5-epoxy-6beta,7-eudesmanolide, 11alpha,13-dihydro-7alpha-acetoxy-3beta-hydroxy-6beta,7-eudesm-4-enolide and 3-keto-beta-eudesmol by comparison of spectral data with those of other 7alpha-hydroxyeudesmanolides.
