RESUMO
Objective To establish the methods for controlling quality of Yiqi Congming Pills, and to improve the quality standard for the pills. Methods Yiqi Congming Pills were sampled from the products of 3 mainpharmaceutical companies in China market, 2 batched from each company. Radix Puerariae, Radix Astragali, Fructus Viticis, Cortex Phellodendri Chinensis, Radix Codonopsis in Yiqi Congming Pills were observed under microscope for microscopic identification. Radix Astragali, Rhizoma Cimicifugae, Radix Paeoniae Alba, and Cortex Phellodendri Chinensis were identified by thin-layer chromatography (TLC) for qualitative differentiation. The contents of puerarin and paeoniflorin in Yiqi Congming Pills were determined by high performance liquid chromatography(HPLC). Results The microscopic characteristics of Radix Puerariae, Radix Astragali, Fructus Viticis, Cortex Phellodendri Chinensis, Radix Codonopsis in the pills were obvious and were easy for discrimination. The spots in thin-layer chromatography (TLC) chromatograms of Radix Astragali, Rhizoma Cimicifugae, Radix Paeoniae Alba, and Cortex Phellodendri Chinensis were clear without interference of negative reference. Puerarin had a good linearity in the range of 0.00112~3.50676μg, and the average recovery rate was 98.2%(sR=1.4%, N=9 ). Paeoniflorin had a good linearity in the range of 0.00333 ~ 3.328 μg, and the average recovery rate was 98.4%(sR = 1.8%, N = 9). Great differences existed in the contents of puerarin and paeoniflorin of Yiqi Congming Pills from the three pharmaceutical companies. Conclusion The established qualitative and quantitative methods are of accuracy, credibility and repeatability, and are effective for controling the quality of Yiqi Congming Pills.
RESUMO
Objective To observe the difference between Radix AstragaLi(RA) and Radix Fici Hirtae(RFH) in immune regulation and improvement of anaemia.Methods Fatigue resistance,brain hypoxia and normal hypoxia tolerance were observed to measure the anti-stress function.Bloodletting-induced anemia model and cyclophosphamid-induced anemia model were used to observe the effect of blood enrichment.Phagocytic function of macrophage,serum hemolysin level and delayed type hypersensitivity(DTH) reaction were also detected.Results RA and RFH could improve the fatigue resistance,normal hypoxia tolerance and brain hypoxia tolerance,and increase the red blood cell count and hemoglobin content,enhance phagocytic function of macrophage and serum hemolysin level,and increase the DTH reaction.Conclusion Both RA and RFH have an effect on improving anti-stress ability,immune function and blood enrichment,and there are no significant difference between RA and RFH.
