Abstract
Five new polyacetylene glucosides, bidensyneosides A1, A2, B, C (1-4), and 3-deoxybidensyneoside B (5), have been isolated from the air-dried whole plant of Bidens parviflora WILLD. The structures were identified based on spectroscopic analysis, physicochemical properties, and application of the modified Mosher method to be 3(R),8(E)-8-decene-4,6-diyne-1,3-diol 1-O-beta-D-glucopyranoside (1), deca-3(R),8(Z) 8-decene-4,6-diyne-1,3-diol 1-O-beta-D-glucopyranoside (2), 3(R)-deca-4,6,8-triyne-1,3-diol 1-O-beta-D-glucopyranoside (3), 3(R),8(E)-8-decene-4,6-diyne-1,3,10-triol 1-O-beta-D-glucopyranoside (4), and 8(E)-8-decene-4,6-diyne-1,10-diol 1-O-beta-D-glucopyranoside (5), respectively. These compounds inhibited nitric oxide (NO) production in lipopolysaccharide and interferon-gamma activated murine macrophages (RAW264.7) and also inhibited histamine release from rat mast cells stimulated by the antigen-antibody reaction.Keywords
