摘要
目的:测定木棉叶中总黄酮的含量。方法:采用紫外分光光度法在258 nm处测定吸光度。结果:对照品溶液在1.32～13.2μg/mL范围内线性关系良好(r=0.9996),平均加样回收率为100.83%,RSD=3.13%。结论:该方法简便、灵敏、准确,可用于木棉叶的质量控制。
Objective： Determine the contents of total flavnoids in leaves of Bombax ceiba L. Method： Determine the absorbance at the wavelength of 258 nm by UV spectrophotometry. Result：Linear relationship was good in the range of 1.32 - 13.2 ug/mL （r =0.9996）, the average recoveries was 100.83 %, RSD =3.13 %. Conclusion： The method is simple, sensitive, accurate, and could be used to control the quality of leaves of Bombax ceiba L.
