Origin discrimination of Taiping Houkui based on HPLC fingerprints and multivariate statistical analysis

  • Received Date: 2021-04-09
  • Taiping Houkui from core and non-core producing areas was taken as the research object. The HPLC fingerprints of Taiping Houkui was established by optimizing high performance liquid chromatography (HPLC) detection methods, and the multivariate statistical methods were used to analyze Taiping Houkui from different producing areas. The results showed that according to the optimized HPLC detection method, the 10 kinds of Taiping Houkui samples from the core producing area were quantitatively analyzed, and 11 common peaks(GA、5-GC、GC、TB、EGC、Cat、EC、Caf、EGCG、GCG、ECG) were identified and well separated, and the similarity of 10 Taiping Houkui samples was above 0.982. Taiping Houkui samples from core and non-core producing areas were clustered together according to the origin in the PCA score chart. The 6 biomarkers (EC, GC, Cat, TB, EGC, Caf) screened out were characteristic components that could distinguish whether Taiping Houkui came from the core producing area.
