Two new furostanol saponins ophiopogonins J (1) and K (2) were isolated from the fibrous roots of Ophiopogon japonicus. The structures of 1 and 2 were established as (25R)-26-O-[(β-D-glucopyranosyl-(1 --> 2)-β-D-glucopyranosyl)]-14-hydroxy-furost-5,20(22)-diene 3-O-[α-L-rhamnopyranosyl-(1 --> 2)]-β-D-glucopyranoside (1), and (25R)-26-O-[(β-D-glucopyranosyl-(1 --> 2)-β-D-glucopyranosyl)]-furost-5,20(22)-diene 3-O-α-L-rhamnopyranosyl-(1 --> 2)[(β-D-xylopyranosyl-(1 --> 4)-β-D-glucopyranoside)] (2) on the basis of spectroscopic means including HRESIMS, 1D, and 2D NMR experiments.

D006027 Glycosides Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed.

D012503 Saponins A type of glycoside widely distributed in plants. Each consists of a sapogenin as the aglycone moiety, and a sugar. The sapogenin may be a steroid or a triterpene and the sugar may be glucose, galactose, a pentose, or a methylpentose. Saponin
