Eight new monoterpenoid glycosides named ligurobustosides A, B, C, E, F, I, J and K were isolated from the leaves of Ligustrum robustum. Their structures were established as geraniol (3'-O-alpha-L-rhamnopyranosyl-beta-D glucopyranoside), geraniol (3'-O-alpha-L-rhamnopyranosyl-4'-caffeoyl-beta D-glucopyranoside), geraniol (3'-O-alpha-L-rhamnopyranosyl-4'-p-coumaroyl beta-D-glucopyranoside), geraniol (3'-O-alpha-L-rhamnopyranosyl-6'-O-p-coumaroyl beta-D-glucopyranoside, 6-hydroxy-3,7-dimethyl-2E,7-octadienyl (3'-O-alpha-L-rhamnopyranosyl-6'-O-p-coumaroyl beta-D-glucopyranoside), 7-hydroxy-3,7-dimethyl-2E,5E-octadienyl-(3'-O alpha-L-rhamnopyranosyl-4'-O-p-coumaroyl)-beta D-glucopyranoside), geraniol-[(3"-O-alpha-L-rhamnopyranosyl-(1 leads to 4)-alpha-L-rhamnopyranosyl)-(4'-O-p-coumaroyl-beta D-glucopyranoside], 6,7-dihydroxy-3,7-dimethyl-2E-octadienyl-(3'-O alpha-L rhamnopyranosyl-4'-O-p-coumaroyl-beta-D glucopyranoside) respectively, by spectroscopic and chemical methods.
