Abstract: Six new polyoxypregnane esters [1-6] having sarcostin or deacetylmetaplexigenin as the aglycones, and acetyl, benzoyl, cinnamoyl, and nicotinoyl residues as the ester moieties linked at C-12 and/or at C-20, were isolated from Leptadenia hastata. In addition, three new glycosides [7-9] with D-cymarose and Doleandrose linked at C-3 were present in the CHCl3, extract. Structures were deduced on the basis of spectral evidence.
