摘要(Abstract):

[Objectives] To establish the quality standard of Shema mixture. [Methods] Thin-Layer Chromatography(TLC) was used to qualitatively identify Ephedra sinica Stapf, Belamcanda chinensis(L.) Redouté and Citrus maxima(Burm.) Merr. cv. Tomentosa in the mixture, and High Performance Liquid Chromatography(HPLC) was established for the determination of the content of ephedrine hydrochloride, which was an effective component of principle drug E. sinica Stapf in the mixture. [Results] TLC was used to identify E. sinica Stapf, B. chinensis(L.) Redouté and C. maxima(Burm.) Merr. cv. Tomentosa in Shema mixture, and the characteristic spots were stable and clear. Ephedrine hydrochloride had a good linear relationship in the range of 2.01-14.06 μg, the average recovery of samples was 98.77%, RSD=1.58%. [Conclusions] TLC and HPLC, as the quality control methods of Shema mixture, have high accuracy and good repeatability, which laid a foundation for the quality control of Shema mixture.
