Abstract:
:Two new furostanol glycosides, ophiopogonins H (1) and I (2), were isolated from the fibrous root of Ophiopogon japonicus. The structures of 1 and 2 were established as (25R)-26-[(O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl)]-22α-hydroxyfurost-5-ene-3-O-[α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside and (25R)-26-[(O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl)]-20α-hydroxyfurost-5,22-diene-3-O-[α-L-rhamnopyranosyl-(1→2)]-β-D-glucopyranoside on the basis of spectroscopic means including HR-ESI-MS, 1D and 2D NMR experiments.
