Four new glycosides named ligurobustosides A, B, C and D have been isolated from Ligustrum robustum and their structures identified as geraniol 3-O-alpha-L-rhamnopyranosyl-beta-D-glucopyranoside (1), geraniol-O-alpha-...Four new glycosides named ligurobustosides A, B, C and D have been isolated from Ligustrum robustum and their structures identified as geraniol 3-O-alpha-L-rhamnopyranosyl-beta-D-glucopyranoside (1), geraniol-O-alpha-L-rhamnopyranosyl-4-cafferoyl-beta-D- glucopyranoside (2), geraniol 3-O-alpha-L-rhamnopyranosyl-4-trans-P-coumaroyl -beta-D-glucopyranoside (3) and geraniol 3-O-alpha-L-rhamnopyranosyl-4-cis P-coumaroyl-beta-D-glucopyranoside (4), respectively.展开更多
Five new monoterpenoid glycosides named ligurobustosides E (1), F (2), I (3), J (4) and K (5) were isolated from the leaves of Ligustrum robustum. Their structures were established by spectroscopic and chemical methods.
