Abstract
Ophiopogonin A, B', C, C', and D', the minor oligosides of Ophiopogonis tuber (tuber of Ophiopogon japonicus KER-GAWLER var. genuinus MAXIM.), have been isolated. The structures of these oligosides have been established as follows : ophiopogonin A (III) : ruscogenin 1-O-[(3-O-acetyl)-α-L-rhamnopyranosyl (1→2)]-β-D-fucopyranoside, ophiopogonin B'(IV) : diosgenin 3-O-[(4-O-acetyl)-α-L-rhamnopyranosyl (1→2)] [β-D-xylopyranosyl (1→3)]-β-D-glucopyranoside, ophiopogonin C (V) : mono-O-acetylophiopogonin D, ophiopogonin C'(VI) : diosgenin 3-O-α-L-rhamnopyranosyl (1→2)-β-D-glucopyranoside (=prosapogenin A of dioscin), ophiopogonin D'(VII) : diosgenin 3-O-[α-L-rhamnopyranosyl-(1→2)] [β-D-xylopyranosyl (1→3)]-β-D-glucopyranoside.
