|Chemical constituents from stem barks of Vernonia cumingiana.[Pubmed: 20822012]|
|The chemical constituents from the stem barks of Vernonia cumingiana were investigated. Various chromatographic techniques such as silica gel chromatography, Sephadex LH-20, ODS column chromatography and HPLC were used to isolate and purify the constituents. The structures were elucidated by spectral methods. Twelve compounds were isolated from the 95% ethanol extract and their structures were elucidated as methyl 3,5-dicaffeoylquinate (1), mEthyl 3,4-dicaffeoylquinate (2), Ethyl 3,4-dicaffeoylquinate (3), methyl 3,4,5-tricaffeoylquinate (4), stigmasterol (5), alpha-spinasterol (6), beta-sitosterol (7), 24-methylene-lanosta-9 (11)-en-3beta-acetate (8), ethyl gallate (9), di-n-butyl-phthalate (10), stearic acid (11) and palmitic acid (12). Compounds 1-12 were isolated from this plant for the first time.
