| Abstract: | Objective To study nitrite scavenging effect of bee pollen polysaccharide and Ethanol extract. Methods Polysaccharide was extracted by the method of water alcohol extraction（WAE）,and the content and the clearance rate to Nitrite were determined by the UV-Spectrometer.The Ethanol extract was prepared by microwave extraction,and the content of flavonoids in it and the clearance rate to nitrite were determined by ultrasonic wave.Results The content of polysaccharide in bee pollen was 2.43%,the content of flavonoids in bee pollen 10.79%.The maximum scavenging rate of polysaccharide to nitrite was 41.7% with the content of 4.317 mg/ml,the maximum scavenging rate of Ethanol extract to nitrite was 25.37% with the content of 2.333 mg/ml.Conclusion The Ethanol extract and polysaccharide of Bashang Bee pollen have higher nitrite scavenging effect. |
| Keywords: | bee pollen polysaccharide flavonoids elimination of nitrite |
