Abstract:Objective To establish the quality standard for Sanghuang of North Korea medicine.Methods Microwave digestion-inductively coupled plasma mass spectrometry(ICP-MS)was used to determine the content of 26 elements in Sanghuang,thin layer chromatography(TLC)was used to identify Sanghuang,the content of Sanghuang′s polysaccharide and total flavonoids were determined by ultraviolet-visible spectrophotometry.Results The r value of standard curve,recovery rate and relative standard deviation(n=6)of 26 elements by ICP-MS met the requirements of Pharmacopoeia of the People′s Republic of China(2020,Volume Ⅳ).The five high content beneficial elements in 10 batches of Sanghuang from different areas were kalium(2772.0-6514.7 mg/kg),magnesium(1299.9-1938.2 mg/kg),calcium(523.62-1753.90 mg/kg),sodium(19.886-359.370 mg/kg)and iron(38.469-534.440 mg/kg).The TLC method was effective in the identification of Sanghuang.There were a good linear relationship of Sanghuang′s polysaccharide in the range of 0.024-0.120 mg(r=0.9982)and the total flavonoids of total flavonoids in the range of 0.2-1.2 mg(r=0.9996).Conclusion According to the Pharmacopoeia of the People′s Republic of China(2020,Volume Ⅰ),the content of five heavy metals and harmful elements in 10 batches of Sanghuang from different places do meet regulations;five high content beneficial elements may be related to the efficacy of Sanghuang;the other 16 low content elements have no safety risk so far.Ten batches of samples from different places are investigated.The established standard can effectively control the quality,which is of great significance to its research and development.
