Flavonoids from the aquatic plant Eriocaulon buergerianum

Four flavonoids including (2 S)-3′,4′-methylenedioxy-5,7-dimethoxyflavan and hispidulin 7-(6- E- p-coumaroyl-β- d-glucopyranoside), and one tocopherol were isolated from the capitulum of Eriocaulon buergerianum KOERN. Their structures were established by spectral and chemical evidence. Flavonoids (2...

Zusammenfassung:	Four flavonoids including (2 S)-3′,4′-methylenedioxy-5,7-dimethoxyflavan and hispidulin 7-(6- E- p-coumaroyl-β- d-glucopyranoside), and one tocopherol were isolated from the capitulum of Eriocaulon buergerianum KOERN. Their structures were established by spectral and chemical evidence. Flavonoids (2 S)-3′,4′-methylenedioxy-5,7-dimethoxyflavan ( 1) and hispidulin 7-(6- E- p-coumaroyl-β- d-glucopyranoside) ( 2) were isolated from the capitulum of Eriocaulon buergerianum. Their structures were established by spectral and chemical analyses.
