Ker-Gawl] is the important medicine used to treat cardiovascular diseases.A new furosteroidal saponin,together with three known steroidal saponins,was isolated from the tuber of Ophiopogon japonicus(Thunb.) Ker-Gawl.The structure of the new furosteroidal saponin,named Ophiopogoside A,was elucidated as 26-O-β-D-glucopyranosyl-(25S)-1β,3β,22α,26-tetrahydroxyfurot-5-ene 3-O-[-α-L-arabinopyranosyl(1→3)]-α-L-rhamnopyranosyl(1→2)-β-D-fucopyranoside mainly by using 1D,2D NMR techniques,ESI-MS analysis as well as chemical methods.展开更多
