Analysis of total flavone in Shuxuening Tablet by resonance scattering spectrum

目的 建立舒血宁片中总黄酮共振散射光谱分析方法 ,探讨共振散射光增强的原因。方法 采用共振散射光谱法研究 BSA- Mo ( ) -槲皮素 (Qu)体系。结果 BSA- Mo( ) - Qu体系在 4 70 nm和 5 2 5 nm产生共振散射峰 ,Qu浓度在 0～ 2 .4 m g/ L 与 4 70 nm处的共振散射光强度成线性关系 ,检测限为 0 .3mg/ L。结论 该方法简便灵敏 ,可用于舒血宁片中总黄酮的测定。 [BSA- Mo( ) - Qu]n

Object To develop a resonance scattering spectral(RSS) method for the determination of total flavone in Shuxuening Tablet, and study the cause of RSS enhancement. Methods The BSA Mo (Ⅵ) qucercetin (Qu) system was investigated by RSS method. Results There were two resonance sacttering peaks at 470 and 525 nm. The Qu concentration in the range of 0-2 4 mg/L is linear to the resonance scattering intensity I 470 nm , with a detection limit of 0 3 mg/L. Conclusion This method is simple, sensitive and suitable for the determination of total flavone in Shuxuening Tablet. The spectral results demonstrate that the formation of [BSA Mo Qu] n associated particle and the interface between the particle solid phase and water phase results to its enhanced RSS.
