ABSTRACT
Objective To establish the quality standard for Shengxinfa Capsule. Methods TLC was used to identify Praeparata, Psoraleae Fructus and Gastrodiae Rhizoma in Shengxinfa Capsule, and 2,3,5,4’-the four-stilbene-2-O-β-D-glucoside was identified by HPLC. The column of Agilent TC-C18 (4.6 mm×250 mm, 5 μm) was used. The mobile phase was acetonitrile-water (15∶85). The flow was 1.0 mL/min and column temperature was 30 ℃. UV detecting wavelength was 320 nm. Results Praeparata, Psoraleae Fructus and Gastrodiae Rhizoma could be identified by TLC. The linear range of 2,3,5,4’-the four-stilbene-2-O-β-D-glucoside was in the range of 0.05-0.50 μg. The average recovery was 97.8% (RSD=0.39%). Conclusion The method is feasible and accurate. The quality of Shengxinfa Capsule can be controlled effectively with the established quality standard.
ABSTRACT
The present work aims at developing a new process to synthesize HMX from DAPT using ultrasound in ionic liquid. Reaction has been carried out in ultrasonic bath, effect of various parameters such as presence and absence of ultrasound, volume and type of solvent, temperature, concentration of nitrating agent has been investigated with an aim of obtaining the optimum conditions for the synthesis of HMX. It was observed that ultrasonically promoted nitroylsis of DAPT to HMX has exhibited significant enhancement in yield at ambient condition.

Objective To study sedative hypnotic pharmacodynamics of Shui'an Capsule,and provide experimental basis for the expansion of clinical indications.Method The effects of different concentrations of Shui'an Capsule on spontaneous activity of mice,induced dormancy of the mice with subliminal and suprathreshold dose of sodium pentobarbital and resisted convulsions of mice caused by Dimenlini Hydrochloridum were observed.Result Shui'an Capsule could significantly decrease times of spontaneous motion in mice,prolong sleeping time with pentobarbital sodium of superthreshold dose,and decrease the latent period of sleep.Conclusion Shui'an Capsule produces obvious sedative hypnotic effect.
