Title: Determination of flavonoids in Polygonatum odoratum by spectrophotometry
Abstract: OBJECTIVE To establish a method for determining flavonoids in Polygonatum odoratum.METHODS The flavonoids in polygonatum odoratum were determined by ultra-violet spectrophotometry at 525 nm.The color reagent was a mixture of NaNO_2-AlCl_3-NaOH solution.RESULTS Data between the flavonoids content and absorbance had a better linear relationship in the range of 0-16 mg·L~(-1)(r=0.9999).The recoveries were in the range of 97.6%-101.4%.CONCLUSION The method is simple,fast and accurate,and it has been applied successfully to determine flavonoids in polygonatum.
