Cycloartane glycosides from leaves of Oxyanthus pallidus
Abstract
From the MeOH extract of leaves of Oxyanthus pallidus, three cycloartane glycosides, named pallidiosides A–C, were isolated together with two known compounds, oleanolic acid and 3-O-β-d-glucopyranosyl-β-sitosterol. The structures of pallidiosides A–C were assigned on the basis of spectral studies and comparison with published literature data. The known compounds were identified by means of Co TLC and confirmed by their physical constants
