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