A new steroidal glycoside from the Ophiopogon japonicus Ker-Gawler (Liliaceae).
A new steroidal glycoside (1), (25R)-14α, 17α-hydroxyspirost-5-en-3β-yl 3-O-α-L-rhamnpyranosyl-(1 → 2)-β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranoside, together with three known steroidal glycosides, (25R)-3β-hydroxyspirost-5-en-1β-yl-3-O-α-L-rhamnopyranosyl-(1 → 2)-O-β-D-xylopyranosyl-(1 → 3)-α-L-arabinopyranoside (2), Cixi-ophiopogon B (3) and Cixi-ophiopogon A (4), were obtained from the tuberous roots of Ophiopogon japonicus (Liliaceae). Compound 2 was isolated from the Ophiopogon genus for the first time. Their structures were identified on the basis of extensive mass and nuclear magnetic resonance spectroscopic analysis.
