| Abstract: | The NaNO_2-Al(NO_3)_3 colorimetry method combined with polycaprolactam purification was developed for the determination of flavonoids in hawthorn.A quickly determining method has been summarized according to optimizing the conditions for colorimetry.The average value of the recovery for flavonoids measurement was 99.9% with the RSD of 1.06%.The result showed that the developed method could be eliminate the interference of impurity and be high precision,correct and reproducible for the determination of total flavonoids in hawthorn. |
| Keywords: | colorimetry method flavonoids horthorn polycaprolactam |
