Establishment of fingerprint and determination of differential components of Sophora flavescens
, and to screen differential components and determine their contents.
METHODS
2
HPLC fingerprints of 12 batches of
S. flavescens
were established by using
Similarity Evaluation System of Chromatographic Fingerprints of TCM
(2012 edition); common peaks were identified and their similarities were evaluated. Chemical pattern recognition analysis [cluster analysis (CA),principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA)]
were performed with SIMCA 14.1 and SPSS 23.0 software, and differential components which influenced the quality of
S. flavescens
were screen with variable importance in the projection(VIP)>1 as standard. Meanwhile, the contents of 4 kinds of differential components were determined by the same HPLC method.
RESULTS
2
There were 17 common peaks in the fingerprints of 12 batches of
S. flavescens
,and their similarities were all higher than 0.96. A total of 6 common peaks were identified, i.e. oxymatrine (peak 1), oxysophocarpine (peak 2), matrine (peak 10), trifolirhizin (peak 14), kurarinone (peak 16) and norkurarinone (peak 17). Results of CA, PCA and OPLS-DA showed that 12 batches of
S. flavescens
were divided into 3 categories according to producing area, i.e. S1-S7 (Shangzhou District of Shaanxi Province) were grouped into one category, S8-S10 (Yichuan County of Henan Province) into one category and S11-S12 (Chifeng City of Inner Mongolia) into one category. VIPs of matrine, norkurarinone, kurarinone and oxysophocarpine and the chemical components represented by peak 11 and 9 were all greater than 1. The contents of matrine, norkurarinone, kurarinone and oxysophocarpine in 12 batches of
S. flavescens
were 2.65-4.93, 1.54-3.44, 9.63-12.94 and 5.08-6.10 mg/g, respectively.
CONCLUSIONS
2
HPLC fingerprint of
S. flavescens
is established successfully in the study, and can be used to screen 6 differential components by combining with chemical pattern recognition analysis, which can provide reference for quality control of
