Extraction of Total Flavone from Bragica juncea Coss and Its Effects on Scavenging of Hydroxyl Radicals
Abstract:ObjectiveTo make use of the resources of Bragica juncea coss, avoid wasting and approach the extraction of total flavanone of Bragica juncea Coss and its effects on scavenging of hydroxyl radicals. MethodsThe flavonoids were extracted by ethanol as the solvent from Bragica juncea coss with ultrasonic wave and ethanol extraction .Using spectrophotometry to extract and check the flavone of Bragica juncea Coss.Results The effect of extracts of Bragica juncea Coss scavenging of hydroxyl radicals was studied.By this method getting the density of the total flavone of Bragica juncea Coss was C=0.4450mg/ml and the rate of recovery was 100.7%. The outcome and the purity of the flavone were all very high . ConclusionThis method is a purely physical process and has not any pollution. It is an ideal way to extract the flavone of Bragica juncea coss. Total flavone from Bragica juncea Coss has effects on scavenging on hydroxyl radicals.
