    Chemical constitutents from pre-formulation of lonicerae japonicae flos in shuanghuanglian lyophilized powder for injection[Pubmed: 22007545]
    To research the chemical constitutents for the pre-formulation of Lonicerae Japonicae Flos (the dried buds of Lonicera japonica) in Shuanghuanglian lyophilized powder for injection and provide substance foundation for the adverse reaction of Shuanghuanglian lyophilized powder for injection.
    METHODS AND RESULTS:
    The chemical constituents were isolated by column chromatography and preparative HPLC. All structures were characterized by the spectroscopic methods including ESI-MS, 1H-NMR, 13C-NMR, and compared with data in the literature. Twenty compounds were isolated and identified as sophoraricoside(1), luteolin-7-O-beta-D-glucopyranoside(2), rutin(3), quercetin(4), 3,5-O-dicaffeoyl quinic acid methyl ester(5), 4,5-O-dicaffeoyl quinic acid methyl ester(6), 3,4-O-dicaffeoyl quinic acid methyl ester(7), 4,5-dicaffeoyl quinic acid(8), 3,4-dicaffeoyl quinic acid(9), chlorogenic acid(10), epi-vogeloside (11), sweroside(12), vogeloside(13), secoxyloganin(14), macranthoidin A(15), Macranthoidin B(16), loniceroside A(17), loniceroside B(18), loniceroside C(19), dipsacoside B(20).
    CONCLUSIONS:
    Compound 1 was identified in genus Lonicera for the first time and compounds 1-20 were isolated from the pre-formulation for the first time.
