| Abstract: | The total flavonoids in Quisgualis indica were determined by spectrophotometry at 500rim with rutin standard and NaNO2-Al （NO3）3-NaOH system. The regression equation was A=11.4486C-0.00543, r=0.9996. The method is simple, reproducible and suitable for the determination of total flavones. |
