ABSTRACT
AIM:
To investigate the process parameters of adsorbing and separating the total flavones of Radix et Rhizoma glycyrrhiae and its assay.METHODS:
Chalcone that flavanone in Licorice root was converted into in alkaline condition was adopted as index and niaringoside as control,through polyamide treatment,alkaline colorimetty was used to determine chalcone content.RESULTS:
Under the condtion,namely, ratio of quantity of Licorice root to polyamide was 21,ratio of column diameter to column heighth was 17,70%ethanol used to eluate,flavone extract was up to 45%with 90%eluting yield.The recoveny of assaying was 98.17%(RSD=2.00%).CONCLUSION:
The purification and assay of Licorice flavonoids are reliable and efficacious.
