Biologically active phenolics from Lilium longiflorum

Abstract The new phenolics, the trans-p -coumaroyl and the feruloyl esters of 2,3-dihydroxy-1,2-propanedicarboxylic acid and itaconic acid, were isolated from Lilium longiflorum ; the cis-p -coumaroyl ester was also detected. The biological activities of the trans-p -coumaroyl ester are described.
