To establish a method for quality evaluation of Artemisiae Scopariae Herba [Artemisia capillaris Thunb. (Mianyinchen)] dispensing granules by combining characteristic chromatogram, quantitative analysis of multi-components by single marker (QAMS) and chemical pattern recognition analysis.
The high performance liquid chromatography (HPLC) characteristic chromatogram was established by 15 batches of Artemisiae Scopariae Herba [Artemisia capillaris Thunb. (Mianyinchen)] standard decoctions and 3 batches of dispensing granules. The contents of 6 components were determined by QAMS. The chromatographic separation was achieved on a AcclaimTM RSLC 120 C18 column (100 mm×2.1 mm, 2.2 μm), with the mobile phase comprising of acetonitrile -0.05% phosphoric acid flowing at 0.4 mL·min-1 in a gradient elution manner. And the detection wavelength was set at 327 nm. The similarity evaluation system of fingerprint of traditional Chinese medicine was used to determine the common peak for similarity evaluation. Hierarchical cluster analysis (HCA) and principal component analysis (PCA) were applied for chemical pattern recognition. The transfer rates of the 6 components from decoction pieces to standard decoctions and dispensing granules were calculated.
The similarities of characteristic chromatograms of 15 batches of Artemisiae Scopariae Herba [Artemisia capillaris Thunb. (Mianyinchen)] standard decoctions and 3 batches of dispensing granules were all above 0.85. And 8 common characteristic peaks were identified. The results of HCA and PCA indicated the similarity of ingredients in formula granules to those in standard decoctions. The contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic, isochlorogenic acid B, isochlorogenic acid A, isochlorogenic acid C in standard decoctions were 1.87-5.23, 7.44-15.26, 2.85-8.18, 3.05-6.14, 0.99-3.93 and 3.23-10.38 mg·g-1 and the transfer rates of these components from decoction pieces to standard decoction were 23.85%-37.28%, 19.57%-31.93%, 28.15%-45.88%, 22.34%-36.59%, 16.64%-28.36% and 21.81%-39.19%, respectively. The contents and transfer rates of these 6 compounds in dispensing granules were close to that of standard decoctions.
The characteristic chromatogram and QAMS method established can be used for quality control and process research of Artemisiae Scopariae Herba [Artemisia capillaris Thunb. (Mianyinchen)] dispensing granules.
