Object To develop a resonance scattering spectral(RSS) method for the determination of total flavone in Shuxuening Tablet, and study the cause of RSS enhancement. Methods The BSA Mo (Ⅵ) qucercetin (Qu) system was investigated by RSS method. Results There were two resonance sacttering peaks at 470 and 525 nm. The Qu concentration in the range of 0-2 4 mg/L is linear to the resonance scattering intensity I 470 nm , with a detection limit of 0 3 mg/L. Conclusion This method is simple, sensitive and suitable for the determination of total flavone in Shuxuening Tablet. The spectral results demonstrate that the formation of [BSA Mo Qu] n associated particle and the interface between the particle solid phase and water phase results to its enhanced RSS.

AIM: To establish an effective and economical processing method for high quality of Calcinatum Alumen with microwave heating. METHODS: A certain amount of Alumen was placed into microwave oven and heated, and its weight was determined by electronic balance every one or five minutes. The quality (appearance, aqueous solubility, water content) of Calcined Alum by microwave was compared with those of products prepared by traditional method, far IR, and electric oven. Moreover, the stability of Calcined Alum in several kinds of package were investigated at room temperature. RESULTS: The microwave for the processing of Alumen has the advantage of rapidness, low cost, and less water content, and its product could be dissolved completely in water. CONCLUSION: Microwave is a practical technique for Alumen processing.

Object To study the application of macroporous resins to the purified active components of Picria fel-terrae Lour., Scutellaria baicalensis Georgi, and Phellodendron chinense Schneid. Methods With the purified active components of Chinese materia medica (CMM) as a standard, we selected the suitable macroporous resins and studied the optimum technological parameters of the adsorption and elution. Results The suitable three types of macroporous resins which were used to the purified active components of CMM were HPD500 for P. fel-terrae., HPD300 for S. baicalensis, and HPD100 for P. chinense. In the absorption course, when the ratios between the medicinal materials amount and the volume of macroporous resins were 1.5 for P. fel-terrae, 0.5 for S. baicalensis and 1 for P. chinense, the purified active components of CMM appeared leaking, and were no more absorbed when the ratios were 11 for P. fel-terrae, 2 for S. baicalensis and 4.75 for P. chinense. In the elution course, the optimum alcohol concentrations were 50% for P. fel-terrae, 30% for S. baicalensis and 50% for P. chinense. Conclusion It is obviously different to refine the active components of CMM, while using the diverse types of macroporous resins.

Object To inquire into the effect on pharmacology of Gejie Dingchuan Capsule (GJDCC). Methods The observation of relieving cough and asthma, removing phlegm, immunity, antibiosis and antiinflammation, antianaphylaxis, and acute and long-term toxicity was carried out. Results GJDCC could resist the convulsion of the isolated trachea of guinea pigs, lengthen the asthma incubation period of guinea pigs, increase the phlegm liquid secreting capacity of isolated rat trachea, promote the pigeon trachea cilium motion, lengthen the mice cough incubation period, restrain the mice ear swelling and rat swelling hyperplasia of granulation, promote the mice producing of serum hemolysin and the lymphocyte conversion rate, and reduce the guinea pig allergic reaction index and shock death rate. It possessed the bacteriostasis, the biggest capacity of bearing consumption was 500 times the clinical daily use and in long-term toxicity test there were not the clear toxicity reactions. Conclusion GJDCC has the function of relieving asthma and cough, removing phlegm, antibiosis and antiinflammation, antianaphylaxis and immunity, without poisonous side effect.
