Objective:To establish an HPLC-ELSD method for the determination of mahuannin A in ephedrae radix et rhizoma. Methods:The content of mahuannin A was determined by an HPLC-ELSD method on an Alltima TM C18 column (250 mm × 4. 6 mm, 5 μm). The mobile phase was acetonitrile-water (28∶ 72) with a flow rate of 0. 7 ml·min-1, and the column temperature was 30℃. The temperature of drift tube heater was 105℃ and the flow rate of carrier gas was 2. 8 L·min-1 . Results:The linear range of mahua-nnin A was 42. 56-383. 04 μg·ml-1(r=0. 999 8). The average recovery and RSD was 99. 9% and 1. 96%(n=6), respectively. Conclusion:The method is simple and the result is accurate. It can be used for the quality control of ephedrae radix et rhizaoma.

Objective:To optimize the extraction process of the total flavonoids from Ephedrae Radix Et Rhizoma. Methods:The purification method of the total flavonoids from Ephedrae Radix Et Rhizoma was optimized with the yield and content of the total fla-vonoids as the indices. Based on the above research, the process parameters were optimized by an orthogonal test. Results:The opti-mum purification conditions were as follows:the volume fraction of ethanol was 50%, the stirring extraction time was 20 min, and the liquid-solid ratio was 8∶ 1(ml·g-1). Conclusion:The optimum purification technology is simple and reproducible, and suitable for the industrial production.

Objective To study the etiology,diagnosis and treatment of xanthogranulomatous cholecystitis (XGC).Methods Clinical data of 78 cases with xanthogranulomatous cholecystitis (confirmed by postoperative pathology) from January 1985 to December 2012 were reviewed retrospectively.Results All 78 cases underwent ultrasonography,50 cases did CT scan.Preoperative diagnosis included chronic calculous cholecystitis in 60 cases,gallbladder carcinoma with cholelithiasis in 8 cases,gallbladder space-occupying lesions in 10 cases.Among those 68 cases of tentative gallstone disease,67 cases were with gallbladder neck incarcerated stones.Surgery were performed in all 78 cases including cholecystectomy in 48 cases,partial cholecystectomy or subtotal resection in 13 eases,cholecystectomy with partial hepatic wedge resection in 12 cases.Intraoperatively 5 cases were misdiagnosed as the carcinoma of the gallbladder and underwent partial liver resection along with cholecystectomy.17 cases underwent choledocholithotomy.2 cases suffered from hepatic duct injury and received Roux-en-Y hepatojejunal anastomosis.Conclusions XGC is a special type of chronic cholecystitis,and accompanied by yellow granuloma formation.Preoperative diagnosis of XGC is often difficult,the definite diagnosis depends on intraoperative fiozen and postoperative paraffin pathology.

Objective:To optimize the extraction process for the total saponins from the root of Thladiantha dubia Bunge. Meth-ods:The extraction technology was optimized by orthogonal experiment with the dissolution content of total saponins as the index and the extraction times, extraction duration and ratio of solid to liquid as the influencing factors. Results:The optimum extraction condi-tions for the total saponins from the root of Thladiantha dubia Bunge were as follows:the reflux extraction was conducted twice(1. 5 h per time) with 70% ethanol as the solvent, and the ratio of solid to liquid was 1 ∶6. Conclusion:The optimum extraction technology is simple, reproducible and stable.

Objective:To establish the quality standard for Chidan Ganxian granules. Methods:TLC was used to identify Paeoni-ae Radix Rubra, Rhizoma Polygoni Cuspidati, Radix Salviae Miltiorrhizae, Herba Saururi and Radix et Rhizoma Rhei in Chidan Ganx-ian granules, and the content of paeoniflorin was determined by HPLC. The stationary phase was an Apollo C18 column ( 150 mm × 4. 6 mm, 5 μm), the mobile phase was acetonitrile-water(12. 5∶87. 5), the flow rate was 1. 0 ml·min-1, the detection wavelength was at 230 nm, and the temperature was 30℃. Results:The characteristic spots of the granules were the same as those of the standard samples without any interference from the negative control. Paeoniflorin had a good linear relationship within the range of 0. 120-1. 436 μg(r=0. 999 4), and the average recovery was 99. 8% with RSD of 1. 80%(n=6).
