Objective To establish an HPLC gradient elution method for simultaneous determination of 4-methoxybenzaldehyde, cinnamyl alcohol, cinnamic acid, cinnamaldehyde, tetrahydropalmatine, dehydrocorydalin, corydaline, and tetrahydroberberine in Zhongjing Weiling Pills, and the results was analyzed by chemometrics method.Methods The HPLC method was used on Agilent Zorbax SB C₁₈ column (250 mm×4.6 mm, 5 μm), and the column temperature was set at 30 ℃. The mobile phase was consisted of acetonitrile and water containing 0.1% glacial acetic acid aqueous solution in gradient elution, and the flow rate was set at 0.9 mL/min. The detection wavelengths were set at 248 nm for 4-methoxybenzaldehyde and 280 nm for cinnamyl alcohol, cinnamic acid, cinnamaldehyde, tetrahydropalmatine, dehydrocorydalin, corydaline, and tetrahydroberberine. The chemometrics evaluation was conducted for the content results of eight constituents in Zhongjing Weiling Pills by Statistical Software.Results There were good linear relationships for4-methoxybenzaldehyde, cinnamyl alcohol, cinnamic acid, cinnamaldehyde, tetrahydropalmatine, dehydrocorydalin, corydaline, and tetrahydroberberine within the ranges of 0.96 — 24.00, 1.78 — 44.50, 20.06 — 501.50, 3.92 — 98.00, 2.89 — 72.25, 2.13 — 53.25, 1.36 — 34.00, and 0.59 — 14.75 μg/mL. Those average recoveries were 96.97%, 97.81%, 100.04%, 99.13%, 98.91%, 96.89%, 97.58%, and 98.34% with the RSD values of 1.04%, 1.51%, 0.54%, 1.01%, 0.92%, 1.32%, 1.36%, and 1.41%, respectively. The chemometrics method showed that the 10 batches of Zhongjing Weiling Pills were divided into three categories. The 1 — 4 principal components were the main factor affecting the quality of Zhongjing Weiling Pills.Conclusion Simultaneous determination of 4-methoxybenzaldehyde, cinnamyl alcohol, cinnamic acid, cinnamaldehyde, tetrahydropalmatine, dehydrocorydalin, corydaline, and tetrahydroberberine by HPLC and chemometrics method can be used to evaluate the quality of Zhongjing Weiling Pills.
