To establish a quantitative analysis of multi-components by single marker (QAMS) method for the simultaneous determination of nine effective components including phenolic acids and flavonoids (neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutoside, isoquercitrin, kaemperol-3-O-rutinoside, 3，4-O-dicaffeoylquinic acid, 3，5-O-dicaffeoylquinic acid, 4，5-O-dicaffeoylquinic acid), in Solidaginis Herba.

Ultra-high performance liquid chromatography was developed on an ACQUITY UPLC^® HSS T3 (100 mm×2.1 mm, 1.8 μm) column with acetonitrile (A)-0.1% phosphoric acid solution (B) as mobile phase in gradient elution. The flow rate was 0.3 mL·min^-1, the detection wavelength was 327 nm, the column temperature was 30 ℃, and the injection volume was 1 μL. Chlorogenic acid and rutoside were chosen as the internal standards for phenolic acids and flavonoids respectively to establish the determine correction factors of neochlorogenic acid, cryptochlorogenic acid，3，4-O-dicaffeoylquinic acid, 3，5-O-dicaffeoylquinic acid, 4，5-O-dicaffeoylquinic acid isoquercitrin and kaemperol-3-O-rutinoside, respectively, by multi-point correction method and their contents were calculated. The results were compared with the results of external standard method to verify their accuracy.

Nine components showed good linear relationships within their own ranges(r≥0.999 5), whose average recoveries were 98.2%-101.7% with the RSDs of 1.0%-1.7%. The contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutoside, isoquercitrin, kaemperol-3-O-rutinoside, 3，4-O-dicaffeoylquinic acid, 3，5-O-dicaffeoylquinic acid and 4，5-O-dicaffeoylquinic acid, in nine batches of samples were 0.008%-0.014%, 0.055%-0.097%, 0.010%-0.019%, 0.191%-0.412%, 0.018%-0.035%, 0.116%-0.50%, 0.028%-0.048%, 0.111%-0.235% and 0.113%-0.182%. The results obtained by QAMS were consistent with those of external standard method(relative average deviations less than 2.8%).

The simple, accurate and reproducible method can be used for the quality control of Solidaginis Herba.
