OBJECTIVE:To compare the new Prescription Regulatory Regime(try out)with the old“Prescription Reg?ulatory Regime”.METHODS:The2prescription regulatory regimes were analyzed in terms of law,standard operating proce?dure of drug dispensing.RESULTS&CONCLUSION:The new Prescription Regulatory Regime(try out)is operated more within the law than the old one,and in which,pharmacists’positions and responsibilities were clearly stated,the limit of checking and monitoring had been enlarged meanwhile drug dispensing standard operating procedures had been clarified.

[Objectivej To establish a gas chromatography (GC) method for the determination of the content of camphor, isoborneol and borneol in Anmo Ointment. [ Methods ] The determination was performed by programmed temperature GC, in which a 100% concentration of dimethylpolysiloxane was used as stationary liquid phase and the GC was equipped with FID detector at 300℃. [Results] The isolation and the linearity were fine with the rate of recovery of camphor 100.5% (RSD being 1.4%), isoborneol 99.1% (RSD being 1.8%) and borneol 100.8% (RSD being 1.3%). [Conclusion] This method is sensitive, rapid and accurate. It can be used to control the quality of Anmo Ointment.

To compare the chemical components of supercritical extracts from Herba Ephedrae and honey-prepared Herba Ephedrae. Volatile oils were extracted from Herba Ephedrae and honey-prepared Herba Ephedrae by supercritical CO 2 extraction and then identified by the combination of gas chromatography and mass spectrometry (GC-MS). Twenty kinds of components such as diethylsulfate obtained from Herba Ephedrae were not found in honey-prepared Herba Ephedrae and twelve different components such as hydroxymethylfurfural were obtained from honey-prepared Herba Ephedrae. The extraction rate of volatile oils was 2.1% in herba ephedrae and 1.0% in honey-prepared Herba Ephedrae. [ Conclusion]The components of supercritical extractions from Herba Ephedrae differ from those in honey-prepared Herba Ephedrae.
