| Abstract:Objective To study the fluorescence properties and analysis method of Tanshinone IIA. Methods Influencial factors including acidic media, the concentrations of substrate on the fluorescence intensity were studied. The stability of fluorescence of Tanshinone IIA was studied. Results Tanshinone IIA had good fluorescent characteristic in pH 2, which had an emission of fluorescence steadily under ultra-vioket radiation. Conclusion The method is simple, sensitive and could be suitable for the qualitative and quantitative analysis. |
