桃胶药材质量标准提升研究OA

Objective To establish a quality standard for the medicinal material Taojiao(Pruni Resina).Methods Thin layer chromatography(TLC)was used for qualitative identification of Taojiao(Pruni Resina).According to the relevant methods in Volume IV of the Pharmacopoeia of the People's Republic of China(2025 edition),the content of impurities,moisture,and total ash were determined.Inductively coupled plasma mass spectrometry(ICP MS)was applied to determine the content of five heavy metals including lead,cadmium,arsenic,mercury,and copper.High performance liquid chromatography(HPLC)was adopted to establish the characteristic chromatogram of Taojiao(Pruni Resina).Results A TLC identification method for Taojiao(Pruni Resina)was established,with clear spots and good separation.The content of impurities,moisture,total ash,and heavy metals met the general requirements for medicinal materials and identification in Volume IV of the Pharmacopoeia of the Peo-ple's Republic of China(2025 edition).The characteristic chromatogram showed good reproducibility and could be used to evaluate quality uniformity and stability,with good representativeness.Conclusion The method is highly specific,accurate,and reproducible,and can be used for the quality control of Taojiao(Pruni Resina).
