Abstract:
OBJECTIVETo study the chemical constituents from the stem bark of Trewia nudiflora.
METHODThe chemical constituents were isolated by silica gel and sephadex LH - 20 column chromatography, and the structures were elucidated by means of spectral analysis.
RESULTTen compounds were obtained from EtOAc fraction of EtOH extract and identified as stigmast-4-en-6beta-ol-3-one (1), stigmast-4-en-6alpha-ol-3-one (2), 7beta-hydroxysitosterol (3), 7alpha-hydroxysitosterol (4), schleicheol 2 (5), taraxerone (6), abbeokutone (7), beta-hydroxypropiovanillone (8), o-vanillyl alcohol (9), glycerol monopalmitate (10).
CONCLUSIONCompounds 1-5 and 7-9 were isolated from this plant for the first time.
