title: Bufadienolides from bulbs of Urginea lydenburgensis (Hyacinthaceae: Urgineoideae).
abstract: Bulbs of the ethnomedicinal hyacinthac Urginea lydenburgensis have yielded two bufadienolides, 16beta-acetoxy-3beta,14beta-dihydroxy-19-formyl-bufa-4,20,22-trienolide (scillicyanosidin) and 4beta,8beta,11alpha,14beta-tetrahydroxybufa-5,20,22-trienolide-12-one, 2alpha,3beta-O-4,6-dideoxy-L-glucose (lydenburgenin).
