Abstract:
In order to comprehensively evaluate the quality of Viticis Fructus, this study established HPLC fingerprints and evaluated the quality of 24 batches of Viticis Fructus samples from different species by similarity evaluation and multivariate statistical analysis(PCA, HCA, PLS-DA). On this basis, an HPLC method was established to compare the content differences of the main components, including casticin, agnuside, homoorientin, and p-hydroxybenzoic acid. The analysis was performed on the chromatographic column(Waters Symmetry C_(18)) with a gradient mobile phase of acetonitrile(A)-0.05% phosphoric acid solution(B) at the flow rate of 1 mL·min~(-1) and detection wavelength of 258 nm. The column temperature was 30 ℃ and the injection volume was 10 μL. The HPLC fingerprint of 24 batches of Viticis Fructus samples was established with 21 common peaks, and nine peaks were identified. Similarity analysis was carried out based on chromatographic data of 24 batches of chromatographic data of Viticis Fructus, and the results showed that except for DYMJ-16, the similarity of Vitex trifolia var. simplicifolia was ≥0.900, while that of V. trifolia was ≤0.864. In addition, the similarity analysis of two different species showed that the similarity of 16 batches of V. trifolia var. simplicifolia was 0.894-0.997 and that of the eight batches of V. trifolia was between 0.990 and 0.997. The results showed that the similarity of fingerprints of these two species was different, but the similarity between the same species was good. The results of the three multivariate statistical analyses were consistent, which could distinguish the two different species. The VIP analysis results of PLS-DA showed that casticin and agnuside contributed the most to the distinction. The content determination results showed that there was no significant difference in the content of homoorientin and p-hydroxybenzoic acid in Viticis Fructus from different species, but the content of casticin and agnuside was significantly different in different species(P<0.01). The content of casticin was higher in V. trifolia var. simplicifolia, while agnuside was higher in V. trifolia. The findings of this study show that there are differences in fingerprint similarity and component content of Viticis Fructus from different species, which can provide references for the in-depth study of the quality and clinical application of Viticis Fructus.
