The whole plant of Leptadenia pyrotechnica afforded 18 new pregnane glycosides (1-18) with sarcostin, 11-hydroxysarcostin, and deacetylmetaplexigenin as the aglycon moieties and acetyl, benzoyl, cinnamoyl, p-coumaroyl, and nicotinoyl ester moieties linked at C-12 and/or C-20 of the aglycon and hexopyranose, 6-deoxy-3-O-methylhexopyranose, and 2,6-dideoxy-3-O-methylhexopyranose sugars linked at C-3 of their aglycon. The structures of these compounds were elucidated by spectroscopic data… CONTINUE READING
