OBJECTIVETo study the chemical constituents from the branch of Trema angustifolia.

METHODThe compounds were isolated by silica gel column chromatography, and their structures were elucidated by means of spectral analysis.

RESULTSix compounds were identified as beta-sitosterol (I), viminalol (II), acetylursolic acid (III), oleanolic acid (IV), paprazine (V), moupinamide (VI).

CONCLUSIONAll the compounds were isolated from this plant for the first time.
