Abstract:
AIMTo study the chemical constituents of Caragana intermedia.
METHODSThe compounds were separated by chromatography methods, their structures were identified by spectral analysis.
RESULTSTen 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).
CONCLUSIONCompound 6 is a new compound and the others were obtained from this plant for the first time.
