Description
Summary:The crude ethanolic extract of the Nepalese sandalwood Osyris wightiana Wall. ex Wight, was analyzed for its bioactive chemical constituents by chromatographic and spectroscopic methods. Phenyl propanoid, benzyl alcohol, iridoid and megastiigmanes, were isolated from the butanolic fraction by the successive use of column chromatography and HPLC. They were isolated as the new source from the genus Osyris. The structures of syringin ( 1 ) and di- O -methylcrenatin ( 2 ), 8-epideoxyloganic acid ( 3 ), citroside B ( 4 ) and roseoside ( 5 ) were characterized on the basis of extensive spectroscopic data analysis of NMR, mass and other spectroscopic techniques.
