The Total Flavanone of Herba Verbenae Extraction and the Identification by Ultrasonic Wave
Abstract:ObjectiveTo make use of the resources of herba verbenae,avoid wasting and approach the extraction of total flavanone of herba verbenae.MethodsThe flavonoids were extracted by ethanol as the solvent from Herba Verbenae with ultrasonic wave and ethanol extraction.Using spectrophotometry to extract and check the flavanone of Herba Verbenae.ResultsThe density of the total flavanone of herba verbenae was C=0.2028 mg/ml and the rate of recovery was 101.4%. Tthe outcome and the purity of the flavanone were all very high.ConclusionThis method is a purely physical process and has not any pollution. It is an ideal way to extract the flavanone of Herba Verbenae.
