STUDY ON THE CHEMICAL CONSTITUENTS OF BIDENS BIPINNATA A NEW POLYACETYLENE GLYCOSIDE

摘要

A new naturally occurring compound 1-polyacetylene glycoside has been isolated form the n- butanol soluble fraction of the leaves of Bidens bipinnata. The chemical structure of 1 was shown to be 3E, 11E—Diethenylene 5. 7. 9—triacetylene, 1, 13—tridecanglycol-2-O-β-D-glycoside named bipinnatpolyacetyloside according to spectral analyses of UV. IR. FDMS, 1H-NMR, H-H COSY, 13C-NMR and DEPT.
