title: Thymofolinoates A and B, new cinnamic acid derivatives from Euphorbia thymifolia.
abstract: Two new cinnamic acid derivatives, thymofolinoates A (1) and B (2) have been isolated from the chloroform soluble fraction of Euphorbia thymifolia and their structures assigned from 1H and 13C NMR spectra, DEPT and by 2 D COSY, HMQCand H MBC experiments. In addition, p-hydroxy cinnamic acid(3), 5-hydroxy-6,7,8,4'-tetramethoxy flavone (4), and 5-hydroxy-3',4',6,7,8-pentamethoxy flavone (5) have also been isolated for the first time from this species.
