Recebido em 14/11/07; aceito em 7/3/08; publicado na web em 9/4/08 CHEMICAL CONSTITUENTS OF Ipomoea subincana MEISN. (CONVOLVULACEAE). The chloroform extract of aerial parts of Ipomoea subincana was submitted to different chromatographic procedures which afforded methyl caffeate, ethyl caffeate, methyl 3,4-dimethoxycinnamate, lupeol, α-amyrin, β-amyrin, 3-β-O-β-D-glycopiranosyl-sitosterol, β-sitosterol, stigmasterol, scopoletin, aromadendrane-4β,10α-diol, n-docosyl-cis-p-coumarate and
more » ... arate and n-icosyl-trans-p-coumarate, vanilin, cinamic acid and vanillic acid. However, from the ethyl acetate extract besides quercetin and 3-O-β-D-glycopiranosyl-quercetin were isolated methyl 4-O-E-feruloyl-5-O-E-caffeoyl-quinate, methyl 3,5-di-O-E-caffeoyl-quinate and methyl 4-O-E-caffeoyl-quinate. The structures of the compounds were established on the basis of spectral data.
