ABSTRACT
Objective: To establish an optimal extraction process of the total glycoalkaloids in Solanum tuberosum L. and then study the anti-inflammatory activity. Methods:The extraction process of the total glycoalkaloids was optimized by orthogonal design. Compared with that of the total glycoalkaloids in Rhizoma Dioscoreae Melanophymatis and fresh potato pieces, the anti-inflammatory ac-tivity of the total glycoalkaloids in Solanum tuberosum L. was evaluated by mouse ear swelling model induced by xylene, rat paw swell-ing model induced by carrageenan, granuloma model caused by cotton and blood capillary permeability experiments. Results:The opti-mal extraction conditions were as follows:the extraction temperature was 65℃, 10-fold amount of methanol was used for twice extrac-tion with 45 min per time. The total glycoalkaloids from the optimal extraction had obvious anti-inflammatory activity,and the effect was related to the content ofα-chaconine. Conclusion:The results show that the order of different factors affecting the extraction rate is ex-traction temperature> extraction time, and the total glycoalkaloids in Solanum tuberosum L. has good anti-inflammatory effects in mice and rats.
ABSTRACT
Objective To establish a method for the determination of berberine and salvianolic acid B in Fuyankang En- ema.Methods The chromatograhie separation was performed on a Kromasil C_(18) column (250 mm?4.6 mm,5?m) with a gradient elution of acetonitrile-0.04 mol/L potassium dihydrogen phosphate solution containing 0.1% phosphoric acid.The flow rate was 1.0 mL/min and column temperature was set at 30℃.The detection wavelength was 230 nm.Results There was a good linearity in the range of 0.0924～2.3100?g (r=0.999 9) for berbeine,and 0.1000～2.5000?g (r=0.999 9) for salvianolic acid B.The average recoveries of berberine at high,middle and low concentra- tions were 100.40 %,99.51% and 99.15 % respectively with RSD being 0.59 %,0.67 %and 1.02 % (n=3) re- spectively.The average recoveries for salvianolic acid B were 101.52 %,99.32 % and 98.68 % respectively with RSD being 0.60 %,0.92 % and 1.00 % (n=3),respectively.Conclusions This method is convenient,specific and re- producible for the determination of berbeine and salvianolic acid B in Fuyankang Enema by HPLC.

ABSTRACT
Objective To observe the effect of Weichangshu Capsule (WCSC) in inhibiting experimental gastric ulcer and the damage of gastric mucosa in SD rats. Methods The experimental gastric ulcer rat models were established by ligation of pylorus, water immersing method and subcutaneous injection of indometacin, and rat models with acute damage of gastric mucosa were induced by hydrochloric acid- ethanol (HAE).Then the effect of WCSC in inhibiting experimental gastric ulcer and the damage of gastric mucosa in SD rats were observed. Results WCSC had obviously inhibitory effects on stress gastric ulcer, indometacin- induced gastric ulcer and HAE- induced acute damage of gastric mucosa. WCSC also inhibited the secretion of gastric juice and increased pepsase activity. Conclusion WCSC has counteraction on experimental gastric ulcer.

METHODS: Nine volatile components were isolated and determined on ZB WAX capillary column(30 m?0.25 mm?0.25 ?m) by GC. The column temperature was raised by program, 50 ℃(3 min)→30 ℃?min -1 →120 ℃(5 min)→10 ℃?min -1 →150 ℃ (1 min)→60 ℃?min -1 →230 ℃(12 min).
