Discussion on Quality Control of Armeniacae Semen Amarum and Its Preparations / 中国实验方剂学杂志

Armeniacae Semen Amarum is one of the most commonly used Chinese medicinal materials， with the homology of medicine and food. It is mild toxicity， in addition to raw product， there are blazed and fried Armeniacae Semen Amarum and other processed products. The prescription， process and quality standard of Chinese herbal preparations containing Armeniacae Semen Amarum in the 2020 edition of Chinese Pharmacopoeia （volume Ⅰ）， were studied and analyzed in this paper. The quality control and safety problems of them were discussed， and the proposals were put forward：①To strengthen the quality control of medicinal materials from the origin， including processing， storage， producing area and so on. ②Production technology is the key factor affecting the safety and effectiveness of preparations， so it is necessary to strengthen the control of production process. ③To strengthen the quality research of Armeniacae Semen Amarum preparations， to develop safety quality control projects， and to further improve the quality standards of Armeniacae Semen Amarum preparations. ④To improve the safety tips of Armeniacae Semen Amarum preparations and standardize the instructions. These suggestions can provide reference for scientific understanding and evaluation of traditional Chinese medicine preparations containing Armeniacae Semen Amarum， in order to promote the quality control level of Chinese medicine preparation containing Armeniacae Semen Amarum and its processed products.

Discussion on polysaccharide determination methods in new Chinese drug research / 中国中药杂志

According to existing problems in polysaccharide determination methods in new Chinese drug applications, the method suitability, chemical reference selection, components interference and method research were introduced. The author suggests that suitable determination method should be selected according to the structure and property of the polysaccharide, and validated. Some influent factors should be examined to assure the accuracy of the method, such as the stability and using amount of the visualizing reagent, visualizing time, maximum detection wavelength etc. Monosaccharide and other water soluble components should be removed from polysaccharide sample, and suitable reference substance and detection wavelength should be selected. It should pay attention to mutual interference of neutral and acidic saccharide, and use inhibitor to eliminate the interference. Because the slopes of the standard curves are different for different monosaccharide, it is proposed that the types and ratios of the monosaccharide in heteroglycan should be understood, and mixed reference substance solution in the ratio is prepared for determination.
