ABSTRACT
Objective:To study the quality standard of Ganyankang capsules. Methods:Rhizoma Polygoni Cuspidati,Radix As-tragali,Radix Pseudostellariae,Herba Scutellariae Barbatae,Oldenlandia diffusa willd,Radix Salviae Miltiorrhizae and Radix Bupleuri in the preapartion were indentified by TLC,and emodin was determined by HPLC. Results:Rhizoma Polygoni Cuspidati,Radix Astra-gali,Radix Pseudostellariae,Herba Scutellariae Barbatae,Radix Salviae Miltiorrhizae and Radix Bupleuri could be obviously identified by TLC. The content of emodin in the capsules was 2. 05 mg·g-1 . The linear relationship was good within the range of 2. 34-74. 88μg·ml-1(r=0. 999 4),and the average recovery was 100. 5% with RSD of 1. 52%(n=9). Conclusion:The quality standard is accurate and reliable,which can be used to control the quality of Ganyankang capsules.
ABSTRACT
Objective: To optimize the water decocting extraction procedures for Ganyangkang capsules by orthogonal design. Methods:Using the extraction yield and emodin content as the indices, the optimal extraction conditions for Ganyankang capsules were studied by L9(34) orthogonal test. Results:The influencing order of the factors was B>A>C (A:extracting time, B:extracting du-ration, C:added water volume) . The optimal preparation conditions were A3 B3 C2 , i. e. adding 10-fold water, decocting extracting 3 times with 2 hours each time. Conclusion:The optimum water decocting extraction procedures is rational and feasible. It can be used in the real preparation.
ABSTRACT
Objective:Deeper studies have been rarely reported on the characteristics and influencing factors of the psychological health of army nurses and on the measures for raising their ability of military stress management. To gain an insight into the psychological state of army nurses in the present military streamlining and to explore its countermeasures. Methods:We investigated the psychological state of 123 army nurses from 6 military hospitals by psychometrical methods and psychological interviews,and analyzed the results. Results:Of the total number of subjects,70.73% scored
