[Studies on chemical constituents from branch of Trema angustifolia].

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.
