title: p-coumaric acid esters from Tanacetum longifolium.
abstract: Two new long chain alkyl p-coumaric acid esters (2-3) along with eicosanyl trans-p-coumarate (1) were isolated from chloroform extract of the roots of Tanacetum longifolium. The structures of new compounds were assigned as 21'-hydroxyheneicosanyl-4-hydroxy-(cis and trans) p-coumarate (2a, 2b) and 27'-hydroxy heptacosanyl-cis-p-coumarate (3) by extensive chromatographic and spectroscopic analysis and by comparison with literature data of known compounds.
