Chemical Constituents of Crepis lignea

doi:A

Abstract

Abstract: Seven compounds were isolated from the acetone extract of the medicinal plant Crepis lignea by column chromatography and recrystallization. Their structures were mainly identified by their spectral and physical data as 3β-acetoxyurs-13(18)-ene (1), lupeol acetate (2), 4-hydroxy-3-methoxycinnamaldehyde (3), (Z)-2-ethylidene-3-methylsuccinic acid (4), olean-12-ene-11a-methoxy-3β-acetate (5), α-amyrin acetate (6) and lupeol-9(11)en-3β-acetate (7) respectively. All compounds were obtained from Crepis lignea for the first time.

Key words: Compositae, Crepis, Crepis lignea, triterpenoids
