Abstract: The chemical composition of Dai Medicine Dichrocephala benthamii has been studied.The ethanol extract in Dichrocephala benthamii  was isolated and purified by silica gel chromatography repeatedly,and the structures were identified by spectral analysis and chemical methods.Results showed that fifteen compounds were isolated from the ethanol extraction of Dichrocephala benthamii and the structures were identified as piperine (1),capsaicin (2),dihydrocapsaicin(3),1H-indole-3-carboxylic acid,ethyl ester(4),1H-indole-3-carboxylic acid,methyl ester (5),3-formylindole (6),pomolic acid (7),floridiolide A (8),16-methoxycleroda-3,13-dien-15,16-olide-18-oic acid (9),16-ethoxycleroda-3,13-dien-15,16-olide-18-oic acid (10),friedelin (11),Kaempferol (12),quercetin (13),syringenin isovalerate (14),gallic acid (15).It can be concluded that compounds 1-12,14 were obtained from the genus of Dichrocephala for the first time.

Key words: Dai medicine, D. benthamii, chemical composition
