Novel biphenyl ether lignans from the rhizomes of Curcuma chuanyujin.
Three new biphenyl ether lignans, 1, 2 and 3, were isolated from the rhizomes of Curcuma chuanyujin along with curcuminoid compounds 4, 5 and 6 and their chemical structures were determined to be 1-feruloyloxy-2-methoxycinnamic acid, 1-feruloyloxy cinnamic acid and (1-p-hydroxycinnamoyl) cinnamic acid by means of spectral evidence. The latter three known substances showed antioxidant activity.
