Chemical investigation of the ethanol extract from the whole plant Liparis odorata (Willd.) Lindl (orchid family) has led to the isolation of three new phenolic glycosides named liparisglycoside A-C (1-3) along with six known compounds (4-9). The structures of compounds were elucidated by means of extensive spectroscopic data analysis and comparison with the literature data. In addition, compounds 3 and 9 revealed inhibitory effects on lipopolysaccharide-stimulated nitric oxide production, and compounds 1, 3 and 9 displayed hypolipidaemic effects in in vitro bioassays.
