Abstract:
AIM: To establish a method of determining the content of total saponin of Radix et Rhizoma Notoginseng in buccal tablets by HPLC. METHODS: Chromatographic conditions are as follows:Hypersil NH_2 column(4.6 mm?200 mm,5 ?m) as the stationary phase,acetonitrile-1% phosphate buffer solution(0-10 min,20:80;10-20 min,25:75;20-25 min,45:55;25-30 min,50:50) as the mobile phase,the velocity of flow is 1.0 mL/min,the temperature of coloum is 35(?C) and the detection wavelength is 203 nm. RESULTS: The HPLC method has good linearity in determining the total saponin of Radix et Rhizoma Notoginseng content,and we can detect four saponins at the same time,linear range,ginsenoside Rg1 0.093 75-6 ?g,ginsenoside Re 0.011 72-0.75 ?g,notoginsenoside R1 0.023 44-1.5 ?g and ginsenoside Rb1 0.140 6-9 ?g,the correlation coefficient r=0.999 9. CONCLUSION: The established method in this article is simple and convenient,with good reproductivity.We can detect four saponins in the total saponin of Radix et Rhizoma Notoginseng Buccal Tablets at the same time by this method.It can be used for quality control of the total saponin of Radix et Rhizoma Notoginseng Buccal Tablets.
