A new monoterpene glycoside (1) isolated from the aerial part of Sibirae angustata RCHD. (Rosaceae) was found to be 1-O-beta-D-glucopyranosyl-geraniol-5,10-olide and named as sibiskoside. Acute toxicity study revealed that oral administration of 1 (2.5 g/kg body weight) to mice resulted in no death
Three new monoterpene glycosides, named sibiraglycoside I(1), J(2) and K(3), were isolated from an aqueous extract of the aerial portion of Sibiraea angustata. Their structures were elucidated on the basis of extensive spectroscopic data analysis (including 1D and 2D NMR and MS experiments) and
Two new monoterpene acylglucosides (1-2) and one new aromatic glycoside (3), together with five known compounds (4-8), were isolated from 95% ethanol extract of Sibiraea angustata. The structures of these compounds were characterized by 2D-NMR and mass spectrometry. Compounds were evaluated for
