Objective To establish an HPLC method for determination of verbascoside, jionoside B1, prim-O-glucosylcimifugin, cimifugin, 5-O-methylvisammioside, sec-O-glucosylhamaudol, atractylodinol, atracylenolide II, and atractylodin in Xiaofeng Zhiyang Granules, and combine chemometrics analysis to comprehensive evaluation of Xiaofeng Zhiyang Granules. Methods The Agilent Zorbax SB-C₁₈ column (250 mm×4.6 mm, 5 μm) was used with acetonitrile-0.2% phosphoric acid solution as the mobile phase with gradient elution. The detection wavelength were set at 330 nm for verbascoside and jionoside B1, 254 nm for prim-O-glucosylcimifugin, cimifugin, 5-O-methylvisammioside, and sec-O-glucosylhamaudol, and 270 nm for atractylodinol, atracylenolide II, and atractylodin. The flow rate was set at 0.9 mL/min, column temperature was set at 25℃, and the injection volume was 10 μL. The cluster analysis and principal component analysis were conducted for the content results of nine constituents in Xiaofeng Zhiyang Granule by SPSS 26.0 statistical software. Results Verbascoside, jionoside B1, prim-O-glucosylcimifugin, cimifugin, 5-O-methylvisammioside, sec-O-glucosylhamaudol, atractylodinol, atracylenolide II, and atractylodin showed good linear relationships within the ranges of 2.53-63.25, 1.09-27.25, 8.17-204.25, 2.38-59.50, 4.07-101.75, 1.74-43.50, 0.66-16.50, 1.47-36.75, and 2.86-71.50 μg/mL, whose average recoveries were 99.01%, 98.17%, 100.13%, 97.63%, 98.72%, 97.22%, 96.93%, 99.24%, and 100.01% with the RSD values of 1.42%, 1.26%, 0.72%, 1.55%, 0.84%,1.06%, 1.18%, 0.67%, and 0.95%, respectively. The samples of 11 batches of Xiaofeng Zhiyang Granules were divided in to 3 categories. The principal component 1-3 was the main factor affecting the quality evaluation of Xiaofeng Zhiyang Granules. Conclusion The method is simple and repeatable, and can be used as an multi-index quality evaluation model for Xiaofeng Zhiyang Granules.
