ABSTRACT
OBJECTIVE:To establish the quality standard of Chushi pill. METHODS:Microscopic identification and TLC were adopted for the qualitative identification of Cortex moutan,C. dictamni,Angelica sinensis,Rubia cordifolia and Gardeniae fructus in Chushi pill;HPLC was performed to determine the contents of paeonol and baicalin. It was performed on column of Kro-masil 100-5 C18 with mobile phase of methanol-water-phosphoric acid(47∶53∶0.2,V/V/V)at the flow rate of 1.0 ml/min,the detec-tion wavelength was 280 nm,the temperature was 25 ℃ and the volume was 10 μl. RESULTS:The microscopic identification showed microscopic characteristics of C. moutan and C. dictamni,and characteristics of A. sinensis,R. cordifolia and G. fructus were identified by TLC;the linear range of paeonol was 0.106 24-2.124 8 μg(r=0.999 9)and baicalin was 0.059 04-1.180 8 μg (r=0.999 9);RSDs of precision,stability and reproducibility tests were no more than 2.06%;average recoveries were respective-ly 101.56%(RSD=1.68%,n=9)and 100.16%(RSD=1.13%,n=9). CONCLUSIONS:The method is simple,accurate and re-producible,and can be used for the quantity control of Chushi pill.
ABSTRACT
Objective To establish the quality standard of Heibu ointment. Method The contents of Galla Halepensis were determined by TLC, and Gallic Acid was determined by HPLC. Results In TLC, the spots were very clear and specific to identify Heibu ointment. The linear range of Gallic Acid was 0.1～1.1 ?g. The quality standard of Heibu ointment was established. Conclusion The method can be used for quality control of Heibu ointment.
ABSTRACT
OBJECTIVE:To discuss the role of Chinese materia medica preparations in hospital traditional Chinese medicine work for references of the development of Chinese materia medica preparations in hospital. METHODS: The importance and role of the research & development, preparation and use of hospital Chinese materia medica preparation in the development chain of Chinese medicine were analyzed. RESULTS & CONCLUSION: The research and preparation of hospital Chinese materia medica preparation make up for the deficiency of the industrial production of Chinese materia medica preparations and play a part in the inheritance and innovation of traditional Chinese medicine.
