Polyacetylenes and flavonoids from the aerial parts of Bidens pilosa.
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.
