The capacity of bee pollen oil is evaluated by these three indicators: ABTS, DPPH radical scavenging and the phosphomolybdate complex. The content of carotenoid is determined by spectrophotometry, and the phospholipid composition is quantitatively analyzed by HPLC. The results show that corn bee pollen oils have strong scavenging ability on the ABTS, DPPH free radicals, and the IC50 values are 0.26±0.01mg/mL2.20±0.05mg/mL respectively. A strong antioxidant capacity has also identified by the Phosphomolybdate complex method. Corn Bee Pollen, in which carotenoid content is 16.21 ± 0.84 mg/100g and the total phospholipid content is 2.98 ± 0.02g/100g, contains five phospholipid composition, namely, PI, PS, PE, PC, LPC. The proportion of carotenoids and total phospholipid in grease is 0.21% and 38.11%. Finally, the conclusion is drawn that corn bee pollen contains a variety of fat-soluble antioxidant active ingredients, can supply hydrogen or electrons, and is an effective natural anti-oxidant resources.
