[Study on the flavonoids constituents of Trachelospermum jasminoides].

OBJECTIVE
To study the flavonoids constituents of Trachelospemum jasminoides.


METHODS
The compounds were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and 2D-NMR.


RESULTS
Six flavonoids were identified as apigenin (I), apigenin 7-O-beta-glucoside (II), apigenin 7-O-beta-neospheroside (III), luteoloside (IV), narngin (V) 6,8-di-C-glucopyanosylapigenin (VI), respectively.


CONCLUSION
Compounds V and VI are isolated from this plant for the first time.
