Quality Evaluation of Traditional Chinese Medicine Jieze Lotion Based on Combination of Fingerprints and Multi-component Quantitative Analysis

OBJECTIVE  To establish fingerprints and multi-components determination of Jieze lotion, and use chemometrics methods for quality evaluation.

METHODS  The HPLC-DAD fingerprints was established and 10 components were recognized by comparison with references. Meanwhile, their contents were determined. The data were evaluated by the methods of chemometrics such as similarity evaluation, cluster analysis, principal component analysis, and orthogonal partial least squares-discriminant analysis.

RESULTS  The similarity of 11 batches of Jieze lotion were all >0.95. The linearity was good(r≥0. 999 1) and the average recoveries were between 89.70% and 106.0% with the RSD of 1.52%−3.41%. Instrument precision, stability and reproducibility of the method were all great. The contents of the common ten components(gallic acid, protocatechuic acid, neochlorogenic acid, caftaricacid, 5-O-feruloylquinicacid, chlorogenic acid, phellodendrine chloride, magnoflorine, 4-O-feruloylquinic acid, berberinehydrochloride) were 40.103−55.841, 2.347−6.179, 8.336−23.810, 7.084−21.956, 33.098−53.833, 24.597−49.610, 21.587−31.188, 5.915−13.162, 115.381−189.702, 31.378−112.686 μg·mL⁻¹, respectively. The results of chemometrics showed that the 11 batches of samples could be divided into 4 categories, and the strong characteristic peaks used to distinguish each batch of samples were berberine hydrochloride, 4-O-feruloylquinic acid, chlorogenic acid, neochlorogenic acid and 5-O-feruloylquinic acid.

CONCLUSION  The method is accurate and reliable, and it can be used for the quality control and comprehensive evaluation of Jieze lotion.
