Scavenging effect of 11 natural plant extracts on DPPH free radical
2, 2-dipheny1-1-Picrylhydrazy1 (DPPH) free radical analysis is a simple method for screening free radical scavenger. In this study,DPPH free radical analysis was used to measure the free radical scavenging activity of bee pollen and various plant extracts, so as to evaluate the experiment The antioxidant capacity of the sample.
The results showed that all the 11 extracts had the ability to scavenge DPPH free radicals, and the ability to scavenge DPPH free gao was positively correlated with the amount of the extracts. Various extracts on DPPH radical scavenging ability of pollen, gingko, propolis, bamboo, radix puerariae, lemon, orange, Chinese wolfberry, definite pieces, poria cocos, fructus schisandrae, which are rich in flavonoids extracts (pollen, ginkgo, propolis, bamboo, puerarin, etc.) have a strong ability to remove DPPH free radicals and the dose effect relationship. In bee products, rapeseed bee pollen extract and refined propolis had the same strong antioxidant effect, and pollen extract had better DPPH free radical scavenging activity than propolis.
