The HPLC system consisted of the Agilent ZORBAX SB-C₁₈ column (150 mm×4.6 mm，5 μm) column with gradient elution of acetonitrile and 0.2% phosphoric acid as the mobile phase at a flow rate of 1.0 mL·min^-1，a detection wavelength of 350 nm，and a column temperature of 30 ℃. Eupatilin was selected as the internal reference substance，the relative correction factors between eupatilin and the other 6 flavanoids were established，and the contents of these 7 constituents in samples were calculated to realize QAMS. At the same time，compared with the external standard method to verify the accuracy and feasibility of the QAMS method.

Within a certain linear range，the relative correction factors between eupatilin and 5-hydroxy-6，7，3’，4’-tetramethoxyflavone，apigenin，hispidulin，kaempferol，jaceosidin as well as casticin were 0.958，1.387，1.000，0.950，0.957 and 1.297，respectively (RSDs of RCFs were less than 2.0%). The contents of 5-hydroxy-6，7，3’，4’-tetramethoxyflavone，apigenin，hispidulin，kaempferol，jaceosidin，eupatilin，casticin in 20 batches of Artemisiae Argyi Folium were 0.031 4-0.623 5 mg·g^-1，0.000 9-0.092 6 mg·g^-1，0.020 6-0.170 7 mg·g^-1，0.011 0-0.184 7 mg·g^-1，0.011 7-0.864 0 mg·g^-1，0.253 2-2.555 0 mg·g^-1 and 0.015 6-0.250 7 mg·g^-1，respectively.

To determine the color of Arnebiae Radix, and the contents of six main purple pigment components (acetylshikonin，β-acetoxyisovalerylalkannin, deoxyshikonin, isobutylshikonin，β，β’-dimethylacrylalkannin and isovalerylshikonin) in Arnebiae Radix, and to study on the correlation between the color of Arnebiae Radix and the contents of six main purple pigment components.

The L，a，and b values of the sample powder were determined using a spectrophotometer to characterize the color of Arnebiae Radix. The International Commission on Illumination (CIE) had developed a Lab color model，which was a digital description of human vision. A higher L value indicated greater brightness，a higher a value indicated redness and a lower a value indicates greenness，and a higher b value indicated yellowing and a lower b value indicates blueness. The contents of purple pigment components were determined using high performance liquid chromatography (HPLC)，and the correlation between L，a，and b values and the contents of six main purple pigments was calculated using SPSS software.

The contents of acetylshikonin in 135 batches of samples ranged from 0.01% to 3.39%. The contents of β-acetoxyisovalerylalkannin ranged from 0.00% to 1.95%. The contents of deoxyshikonin ranged from 0.00% to 0.23%. The contents of isobutylshikonin ranged from 0.01% to 1.13%. And the contents of isovalerylshikonin ranged from 0.02% to 2.88%. The contents of β，β’-dimethylacrylalkannin ranged from 0.01% to 2.17%. There was a significant negative correlation between the contents of acetylshikonin，β-acetoxyisovalerylalkannin and isobutylshikonin and the L (black_white) chromaticity value of Arnebiae Radix，with a Spearman correlation coefficients between -0.138 and -0.222. The chromaticity value of a (red_green) was related to the five components other than acetylshikonin，which were β-acetoxyisovalerylalkannin，deoxyshikonin，isobutylshikonin，β，β’-dimethylacrylalkannin，and isovalerylshikonin，with a spearman correlation coefficients between 0.176 and 0.355；b (blue_yellow) chromaticity value was related to the five components other than β-acetoxyisovalerylalkannin，which were acetylshikonin，deoxyshikonin，and isobutylshikonin，β，β’-dimethylacrylalkannin. β，β’-dimethylacrylalkannin was positively correlated with a coefficient of 0.290，and negatively correlated with the other four components with a coefficients between -0.325 and -0.633.

It is recommended that the assay limits of Arnebiae Radix be revised to β，β’-dimethylacrylalkannin not less than 0.30% and isovalerylshikonin not less than 0.29%.

Ten chromatographic peaks were identified，including puerarin (Pu)，daidzin (Da)，daidzein (Dae)，genistin (Ge)，genistein (Gee)，kakkalide (Ka)，glycitin (Gl)，tectoridin (Td)，tectorigenin (Tg) and tectorigenin-7-O-xylosylglucoside (Tx)，and HPLC method for the determination of the above ten components was established simultaneously. The results of PCA and PLS-DA could distinguish four kinds of samples with different commercial specifications. Gl，Tx，Ge，Td，Ka and one unknown compound 6 were the components with significant differences between the samples with four different commodity specifications. The chemical components of GH and FGH were obviously different from their adulterants. The content of Ka in GH were 10 times as much as that in FGH，and the content of Ge was half as much as that in FGH. Da，Gl was not detected in GH.
