ABSTRACT To study the chemical constituents from the branch of Trema angustifolia.
The compounds were isolated by silica gel column chromatography, and their structures were elucidated by means of spectral analysis.
Six compounds were identified as beta-sitosterol (I), viminalol (II), acetylursolic acid (III), oleanolic acid (IV), paprazine (V), moupinamide (VI).
All the compounds were isolated from this plant for the first time.
