| Abstract: | Objective To investigate the extraction and distinguishing method of total flavanone of Nephrolepis cordifolia(L.) Presl.Methods The flavonoids were extracted by ethanol as the solvent from Nephrolepis cordifolia(L.) presl with ultrasonic wave and ethanol extraction.The flavanone of Nephrolepis cordifolia(L.) Presl was checked and determined by spectrophotometry.Results The content of the total flavanone of nephrolepis cordifolia(L.) Presl obtained by this method was C=0.4039 mg/ml and the rate of recovery was 102.6%.Conclusion This text provides the extraction and purifying methods to get the outcome and the purity of the flavanone.This method is a purely physical process and has no pollution.It is an ideal way to extract the flavanone of Nephrolepis cordifolia(L.) Presl. |
