Quality control of Jiangzhi Jianfei Tablets / 中成药

ABSTRACT

AIM:To establish the methods of determining 2,3,5,4′-tetrahydroxystilbene-2-O-?-D-glycoside,puerain;ginsengnoside Rg_1,ginsengnoside Rb_1,notoginsengnoside R_1,and salvianolic B in Jiangzhi Jianfei Tablets(Radix Polygoni multiflori,Radix Puerariae lobatae,Radix et Rhizoma Notoginseng,Radix et Rhizoma Salviae miltiorrhizae,etc) with HPLC. METHODS: All chromatogram columns used were ODS columns.The mobile phase of acetonitrile-wate(25(∶)75) was chosen for 2,3,5,4′-tetrahydroxystilbene-2-?-D-glycoside.The flow rate was 1.0 mL/min.The detection wavelength was at 320 nm.The mobile phase of methanol-water(25(∶)75) was chosen for puerain.The flow rate was 1.0 mL/min.The detection wavelength was at 250 nm.The mobile phase of acetonitrile-water was chosen for ginsengnoside Rg_1,ginsengnoside Rb_1 and notoginsengnoside R_1.The flow rate was 1.0 mL/min.The detection wavelength was at 203 nm.The mobile phase of methanol-acetonitrile-methane acid-water(30(∶)10(∶)1(∶)59) was chosen for salvianolic B.The flow rate was 1.0 mL/min.The detection wavelength was 286 nm. RESULTS: The linear rangers were 0.476 ?g-4.760 ?g(r=0.999 6) for 2,3,5,4′-tetrahydroxystilbene-2-?-D-glycoside,0.168 96 ?g-1.689 6 ?g(r=0.999 8) for puerain,0.724 ?g-7.240 ?g(r=0.999 8) for ginsengnoside Rg_1,0.728 ?g-7.280 ?g(r=0.999 9) for ginsengnoside Rb_1,0.23 ?g-2.30 ?g(r=0.999 8) for notoginsengnoside R_1,0.306 ?g-3.060 ?g(r=0.999 9) for salvianolic B.Their average recoveries were 99.43%(RSD=1.08%,n=6),99.43%(RSD=1.66%,n=6),101.17%(RSD=2.08%,n=6),and 102.39%(RSD=2.60%,n=6),respectively. CONCLUSION: These methods of determining components in four kinds of herbs are simple,accurate,reproducible and can be used for quality control of Jiangzhi Jianfei Tablets.
