Abstract

Okanin 4′-O-β-D-(2″,4″,6″-triacetyl)-glucoside, okanin 4′-O-β-D-(6″-trans-p-coumaroyl)-glucoside, both new natural compounds, and okanin 3′-O-β-D-glucoside have been isolated from the leaves of Bidens pilosa L. Their structures have been elucidated by means of UV, FD-MS, 1H-NMR, and 13C-NMR spectroscopy. NMR spectral data for okanin 4′-O-β-D-glucoside (marein) are given.
