| Abstract: | 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. |
