ABSTRACT
Objective To study the immunomodulatory property of Compound Shougong powder(SGS) on S180 tumor-bearing mice.Methods The S180 model of tumor-bearing mice by Kunming mice were prepared.Then,the tumor-bearing mice were randomized into the model group,positive control group,and SGS groups (29.25g/kg,19.50g/kg,9.75g/kg).Besides the normal group,the other groups were used intragastric administration of into tumor-bearing mice by one time,14 consecutive days.The carbon clearance,quantitative hemolysis and DNFB induced delayed-type hypersensitivity were applied to assay effects of SGS on nonspecific immunity,humoral immunity and cellular immunity.Results Compared with the model control group,in the SGS groups,the tumor-bearing mice with spleen and thymus index of organ improved (all P ＜ 0.05),and the clearance index and values of phagocytic index were elevated(all P ＜0.05),and the productions of IgM and IgG in serum and hemolysin in splenocytes were enhanced(all P ＜0.05),and the percentages of T cells expressing CD4+,CD8+ and the ratio of two subset of T lymphocyte increased,and the IL-2 production of spleen lymphocytes was also improved (all P ＜ 0.05).Conclusion SGS showed significant immunomodulatory property on tumor-bearing mice through specific and nonspecific immunity.
ABSTRACT
Objective To study the best processing technology of Xanthii Fructus by determining the contents of chlorogenic acid and 3,5-dicaffeoylquinic acid in which processed by different temperature and time. Methods Sixteen batchs samples of Xanthii Fructus were propressed by stir-frying with sand, and the propressed temperature and time were set at 150-220 ℃ and 0.5-7 minutes. Two phenolic acid components in Xanthii Fructus were simultaneously determined. The column was UPLC Acquity BEH C18 (2.1 mm×100 mm, 1.7 μm). The mobile phase was acetonitrile-0.1% phosphoric acid, gradient elution. The flow rate was 0.25 mL/min, and the detection wavelength was 327 nm. Results The sample with highest contents of chlorogenic acid and 3,5-dicaffeoylquinic acid was the batch processed by stir-frying with sand at 160 ℃ for 7 minute, which was 2.498, 2.004 mg/g, respectively. Conclusion According to the appearance of processed sample and the content of chlorogenic acid and 3,5-dicaffeoylquinic acid, the optimal processing technology of Xanthii Fructus was stir-frying with sand at 160 ℃ for 7 min.
ABSTRACT
Objective To establish an HPLC method for the determination of Aloeemodin,Rhein,Chrysophanol,Emodin and Physcione in Huangxiong Kangshuan Capsule.Methods The determination was performed on Kromasil-C18 column(250 mm?4.6 mm,5 ?m) with mobile phase consisted of methanol-0.1% phosphoric acid(85:15) at a flow rate of 1.0 mL/min.Column temperature was 25 ℃.The UV detection wavelength was set at 254 nm.Results The calibration curves were linear in the range of 0.230～3.68 ?g(r=0.999 8) for Aloeemodin,0.224～3.584 ?g(r=0.999 9) for Rhein,0.223～3.568 ?g(r= 0.999 8) for Emodin,0.257～4.112 ?g(r=0.999 9) for Chrysophanol and 0.287～4.592 ?g(r=0.999 8) for Physcion.The average recovery was 98.48%,98.10%,99.08%,100.34%,97.52% and RSD was 1.39%,1.54%,1.44%,2.40%,2.03% respectively.Conclusion The determination method is simple,reliable,accurate,and it can be used for quality control of Huangxiong Kangshuan Capsule.
