摘要 以木犀草素与氯化铁为原料,利用紫外分光光度法探讨了木犀草素(Luteolin,简写为Lut)与过渡金属离子(Fe3+)的配位作用,结果表明在pH=9.0~10.0、木犀草索FeCl3物质的量之比为1∶1或2∶1时在60℃下反应2h能形成较稳定的金属配合物.在乙醇溶液中,在最佳反应条件下合成了木犀草素-铁配合物,并利用紫外光谱对配合物进行了结构表征. The coordinative reaction between Luteolin and Fe(Ⅲ) were studied by UV Spectrometry with Luteolin and FeCI3. The results showed the optimal reaction conditions for the Lut- Fe(Ⅲ) complex were at the pH of 9.0-10.0, molar ratio of 1:I or 1:2 (Luteolin and FeCl3 ), temperature 60 ℃ and two hours of reaction time. In ethanol solution, the complex of Luteolin - Fe(Ⅲ) was synthesized in the optimal conditions and charactered by UV spectra.
