Methods:HPLC conditions were as fellows: Chromasil C 18 column, a mobile phase of CH 3CN-H 2O(25∶75), and the wavelength at 320nm. Results:2,3,5,4′-tetrahydroxystilbene-2-O-?-D-glucoside was linear within the range of 0.044～ 0.7 ?g with a correlation coefficient of 0.9999. The average recovery was 98.54%. Conclusion:The method is simple, swift, accurate and practical in quality control of Jiangzhitongmai Tablet.

Objective To investigate the effect of different transdermal enhancers on percutaneous absorption of ephedrine in Compound Herba Ephedrae Adhesive Plaster.Methods Using modified Franz diffusion cell,the ephedrine content was determined to investigate the effect of different transdermal enhancers in promoting percutaneous absorption.Results Azone or azone used together with other transderml enhancers had a better effect in promoting percutaneous absorption,indicating that azone was the leading transderml enhancers for ephedrine.The mixed transdermal enhancer of azone and propylene glycol was the most effective combination and the rate constant of percutaneous absorption is 94.280 ?g?cm-2?h-1.Conclusion The mixture of azone and propylene glycol can enthance the percutaneous absorption of ephedrine and can be used as the transdermal enhancers for this compound plaster.

Objective To establish the quality control standard of Pinellia Heart-Sedating Granules. Methods TLC methods for identifition of Radix Pinellia and Radix Scutellariae were established. A simple HPLC was established for the determination of Berberine hydrochloride. Results The spots on TLC plates were clear without interference in the blank reference. The liner range of Berberine hydrochloride was 0.009375～0.3 ?g,r =0.9 999. The average recovery of Berberine hydrochloride was 101.46% and RSD was 2.88%. Conclusion The method is simple, accruate, reproducible and can be used as the quality control method for Pinellia Heart-Sedating Granules.

Objective To investigate the process of best extraction for Bujing Yishen Granules.Methods The orthogonal test was employed for selecting the best extraction process,with the extraction rate of Icariin as criteria.The levels of water amount,extracting time and times were studied.Result The super extraction process was adding 10 times amount of water and 1.5 hours for the first time,then adding 8 times and 1.5 hours for the second time.Conclusion The method is stable,reasonable and feasible.

Objective To optimize an extracting technology for Fufang Baige capsule. Methods The orthogonal design was used for the inspection of water-extracting process and alcohol-precipitating process. Water volume, extracting time and extracting times were screened as inspection elements for water-extracting process. And liquid concentration, alcohol-precipitating concentration and incubating time were screened as inspection elements for alcohol-precipitating process. The transferring rate of paeoniflorin which is the indicator component in drug-Jun was screened as the inspection indicator for each fraction of extraction process. Results The optimal extraction conditions were as follows:for water- extracting process, that was extracting 2 times with 15-fold water, 2 hours for each time ; For alcohol-precipitating process, that was concentrating liquid to 1.0 g/mL Chinese herbs containing, then adding alcohol untill alcohol concentration ammouted to 70%, and at last putting it static for 18 hours. Conclusion The extracting technology was simple, economical and practical, and was able to increase production efficiency.

According to two theories,which are "traditional Chinese medicine researching is in the face of a complex opening gigantic system" and "Chinese materia medica compound(CMMC) is the natural combinatorial chemical libraries",the study on active fractions of CMMC has been facing to a complex system with a large number of data that is non-linear,multi-variable,and varieties related to each other.The thinking and method of "combinatorial screening" has been put forward based on these two theories,that is the principle "using the diverse structures of molecules to simulate the diverse organism" used in combinatorial chemistry and the data mining technique was taken into the study on complex system of CMMC.In order to create combinatorial libraries,the two methods were used to obtain the fractions of CMMC.Re-combination group of the CMMC was used,and various industrial separation techniques, such as resin,membrane,were used to replace the diversity of chemosynthesis routes to create "Building Block".Through data mining and knowledge discovery, the intrinsic correlation of CMMC "multi-components and multi-targets" between the chemical composition and the mechanism was carried out.The new technologies which aim at high-throughput screening of CMMC were explored,in order to provide the evidence for setting up an idea with "optimal separation" and optimization design about application system of refining technology.

OBJECTIVE:To provide reference for the improvement of Pharmaceutical Equipment & Workshop Design teach-ing. METHODS:Task-driven teaching was adopted,CIDO engineering educational model was referred to,task was designed from the conception to run with task-based;theoretical and teaching exploration and practice was carried out by cross-learning of individ-uals and groups,applying of pilotscale experiment platform,developing course design and forming evaluation. RESULTS & CON-CLUSIONS:It changed the traditional teaching method that emphasized on class teaching to make students participate in multi-task learning,so that students can better grasp the equipment selection,understanding and application of workshop design in pharmaceu-tical process. The method gives full play to students' initiative and creativity and it is conducive to students’comprehensive ability for adapting the development of pharmaceutical industry.
