Camptothecins and two new monoterpene glucosides from Ophiorrhiza liukiuensis.
Two new monoterpene glucosides, demethylsecologanol and 3'''-O-glucosylsenburiside II, were isolated from Ophiorrhiza liukiuensis (Rubiaceae) together with 23 known compounds, including camptothecins and beta-carboline-type alkaloids. Their structures were determined by spectroscopic analysis.
