[Studies on flavonoid constituents of Caragana intermediia].
OBJECTIVE
To study the chemical constituents of Caragana intermedia.


METHODS
The compounds were separated by chromatography methods, their structures were identified by spectral analysis.


RESULTS
Ten compounds were isolated and identified as 5,7,4'-trihydroxy-3,3'-dimethoxyflavone (1), 3,5,7,8,4'-pentahydroxy-3'-methoxyflavone(2), puercetin(3), limocitrin(4), 5,7,3',4'-tetrahydroxy-3-methoxyflavone(5), 7,3',5'-trihydroxyflavanone(6), 5,7,3',4'-tetrahydroxy-3,8-dimethoxyflavone(7), butein(8), liquiritigenin(9) and 5,7,4'-trihydroxy-3,8-dimethoxyflavone(10).


CONCLUSIONS
Compound 6 is a new compound and the others were obtained from this plant for the first time.
