Polyacetylenes and Flavonoids from the Aerial Parts of Bidens pilosa

Abstract

Bidens pilosa is used in various folk medicines such as antimalarial, antibacterial, blood pressure-lowering, and antihyperglycemic agents. Phytochemical investigation of the aerial parts of this plant yielded 10 polyacetylenes and 9 flavonoids, including four new polyacetylenes (5, 7–9) and one new chalcone glucoside (11). The molecular structures of the isolated compounds were elucidated by comprehensive spectroscopic analysis.

Key words

Bidens pilosa - Asteraceae - polyacetylene - flavonoids
