Panax japonicus C. A. Mey.(Bai San Qi,白三七) is recognized as an effective and rare medicinal plant to treat weakness, fatigue and rheumatism in Tu Jia ethnomedicine. This paper is to discover more substance evidence for the application of Tu Jia ethnomedicine. Methods Column chromatography and preparative high performance liquid chromatography (HPLC) was applied for isolation and purification;1H-NMR, 13C-NMR, 1H-1H COSY, HSQC and HMBC NMR spectra were applied for structure identification;Methyl thiazolyl tetrazolim (MTT) assays were applied for cytotoxicity evaluation. Results Totally 12 known compounds were isolated by column chromatography and preparative HPLC from rhizomes of Panax japonicus C. A. Mey.(Bai San Qi,白三七). Structures of these compounds were identified by their NMR spectra. All the 12 compounds were triterpenoid saponins. Five of them were oleanolic acid type, and the remaining 7 were dammarane type. Eleven compounds were assayed for their cytotoxic activity against Hep G2 human liver cancer cell lines and BGC-823 human gastric cancer cell lines. Three of the 11 showed relatively dominant cytotoxicity against these cell lines. Conclusions A total of 12 known compounds have been identified from Panax japonicus C. A. Mey.(Bai San Qi,白三七);NMR spectra of compounds with similar skeletons showed regular characteristics;3 compounds showed relatively dominant cytotoxicity against Hep G2 and BGC-823 cancer cell lines, and the result can be valued as weak while setting the taxol as a positive control.展开更多
目的:观察芪白平肺胶囊对慢性阻塞性肺疾病(COPD)痰瘀阻肺证模型大鼠肺功能、形态学改变以及对于血清Rock-1(Rho关联卷曲蛋白激酶1)、Rho关联卷曲蛋白激酶2(Rock-2)表达的影响。方法:健康SD雄性大鼠50只,随机分组为正常对照组、模型组...目的:观察芪白平肺胶囊对慢性阻塞性肺疾病(COPD)痰瘀阻肺证模型大鼠肺功能、形态学改变以及对于血清Rock-1(Rho关联卷曲蛋白激酶1)、Rho关联卷曲蛋白激酶2(Rock-2)表达的影响。方法:健康SD雄性大鼠50只,随机分组为正常对照组、模型组、芪白平肺胶囊低剂量组、芪白平肺胶囊高剂量组、法舒地尔组,复制COPD痰瘀阻肺证大鼠模型,每日造模结束后予大鼠灌胃。模型组、正常组每天生理盐水灌胃10 m L/kg,芪白平肺胶囊低剂量组、芪白平肺胶囊高剂量组每天给药量分别为1000 mg/kg、250 mg/kg(含芪白平肺胶囊50 mg/m L),法舒地尔每天给药量为2 m L/kg(含法舒地尔15mg/m L),每只大鼠每日灌胃1次,直至造模结束,测定大鼠肺功能、观察肺血管重构的病理改变,ELISA检测模型大鼠血清Rock-1、Rock-2的表达。结果:模型组肺小动脉管壁变厚、管腔变小,血清中Rock-1、Rock-2较正常组含量显著升高,(P<0.01);FEV0.3、FEV0.3/FVC、PEF均明显降低,差异有统计学意义(P<0.01);各治疗组与模型组比较肺小动脉管壁变薄,管腔增大,血清中Rock-1、Rock-2表达水平均有不同程度下降(P<0.01-0.05)。结论:芪白平肺胶囊对COPD大鼠的肺组织具有保护作用,可有效的防止痰瘀阻肺证慢阻肺模型大鼠肺功能的下降,降低COPD痰瘀阻肺证模型大鼠血清Rock-1、Rock-2表达水平。展开更多
