Figure 3. The contents of lutein, zeaxanthin, and β-carotene detected in the livers of the ApoA-I−/−/Bco2−/− mice and the Bco2−/− mice by HPLC.

Figure 3.

The levels of all three carotenoids in the liver of the ApoA-I−/−/Bco2−/− mice were increased compared with the Bco2−/− mice. The contents of β-carotene in both mice are 5 to 10 times higher than lutein and zeaxanthin, indicating that β-carotene can preferentially accumulate in the liver. The ratio of lutein:zeaxanthin:β-carotene is 1.0: 2.1: 11.7 in the Bco2−/− mice, while it becomes 1.0: 2.0: 15.6 in the ApoA-I−/−/Bco2−/− mice. Carotenoids were extracted from twenty liver samples of the ApoA-I−/−/Bco2−/− mice and twenty liver samples of the Bco2−/− mice. *, P<0.05. Error bars represent standard deviation.
