Abstract:
Objective:To explore the antioxidant activity of natural plant ingredients lemon essential oil(LEO),limonene(LIM) and tea polyphenol(TP).Methods:The UV-Vis spectrometry was used to determine the 3 agents on the scavenging activity of 1 ,1 diphenyl-2-trinitrobenzene hydrazine free radicals(DPPH·)and hydroxyl free radical (·OH).Results:LEO,LIM and TP showed scavenging effect on the 2 kinds of free radicals.The (DPPH·)scavenging effect:LEO(IC50 =0.01 4)>TP(IC50 =0.01 4)>LIM (IC50 =0.002);the (·OH)scavenging effect:TP(IC50 =0.079)>LEO(IC50 =0.01 3)>LIM(IC50 =0.004).In a certain con-centration range,scavenging effect was increased with the concentration increase.Conclusion:As a nontoxic natural extract,lemon essential oil has strong antioxidant activity.
