14,15-Secopregnane-Type Glycosides with 5α:9α-Peroxy and Δ6,8(14)-diene Linkages from the Roots of Cynanchum stauntonii
Three new 14,15-secopregnane-type glycosides, stauntosides UA, UA1, and UA2, were isolated from the roots of Cynanchum stauntonii. The three compounds share the first reported and same basic structural features of 3β-hydroxy-14:16,15:20,18:20-triepoxy-5α:9α-peroxy-14,15-secopregnane-6,8(14)-diene na...
