Abstract: In order to provide theoretical basis for rational exploitation and utilization of ginseng resources, the differences of active antioxidants and chemical components in extracts from different parts of ginseng were compared. 1,1-Diphenyl-2-trinitrophenylhydrazine (DPPH) radical scavenging assay, 2,2'-biazo-bis-3-ethylbenzothiazoline-6-sulfone (ABTS) radical scavenging assay and ferric ion reduction assay (FRAP) were used to evaluate the antioxidant activities of different ginseng extracts. The compounds in ethyl acetate (EAE) extracts from different parts of Panax ginseng were identified and compared by gas chromatography-mass spectroscopy (GC-MS). The results of DPPH, ABTS and FRAP experiments show that the EAE extracts of ginseng stem and leaf have the best antioxidant effect. The half inhibition concentration (IC50) value of DPPH is (0.66±0.02) g/L, and the IC50 value of positive drug-2,6-BHT is (0.26±0.02) g/L. The IC50 value of ABTS is (0.54±0.26) g/L, and the IC50 value of BHT is (0.15±0.04) g/L. The EAE of FRAP test is (272.09±3.78) mg/L, and the positive BHT value is (1319.37±3.80) mg/L. By GC-MS analysis, 20, 27, 14 and 14 components are identified from the EAE extracts of ginseng root, ginseng folium, ginseng flower and ginseng seed, respectively, of which one common component is linoleic acid. This study provides a theoretical basis for better exploitation and utilization of ginseng resources and intensive processing of antioxidant food and cosmetic products.
