Objective To investigate the main active components of different monthly Tetrastigma hemsleyanum Diels et Gilg (TDG) from Zhoushan City and establish the map of different monthly TDG. Methods The quality of different monthly TDG was evaluated by combining fingerprint similarity evaluation cluster analysis (CA), principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). An InterSustainSwift C18 chromatographic column (4.6 mm×250 mm, 5 μm) was used, with acetonitrile-0.1 formic acid aqueous solution as the mobile phase, gradient elution, flow rate of 0.8 mL/min, detection wavelength of 20 nm, column temperature of 30 ℃, and injection volume of 10 μL. Results The fingerprint similarity evaluation results of 12 batches of different monthly TDG showed that the similarity of different monthly TDG samples varied greatly; the 13 common were identified, and 3 common peaks were recognized; CA, PCA, and OPLS-DA analysis could all classify the 12 batches of different monthly TDG into 3 categories; and 2 differential quality markers, gallic acid and quercetin, were screened out by analyzing the variable importance in projection (VIP) values under OPLS-DA. Conclusion The high performance liquid chromatography (HPLC) fingerprint and multi-component content determination method established in this study is stable and reliable, and can provide a reference for quality control of Zhoushan TDG.
