Abstract:
Objective To establish the quality standard of Yuling Tea for its quality control. Methods Astragalus, Fructus cnidii L, Schisandra chinensis and Lycii Fructus in Yuling Tea were identified by TLC. The content of Schisandrin was determined by HPLC. Welch Materials C18 column (250 mm×4.6 mm, 5 μm) with mobile phase of methanol-water (70∶30) was used. The detective wavelength was 250 nm. Results The TLC for identification was simple and special. Schisandrin showed a good linear relationship in 0.222-0.222 0 μg, r=0.999 9. The average recovery was 98.96%, and RSD was 0.74%. Conclusion The method can accurately determine the content of Schisandrin in Yuling Tea. It can be used for quality control of the preparation.
