No. 8 Improvement of Antioxidant activity by using astaxanthin γ-CD complex

Astaxanthin(Ax) is an antioxidant and it protect human from oxidative stress such as UV damage or lipid peroxidation.

Ax-γ-CD complex has much more antioxidant activity than and Ax behave by itself.

The graph above shows that oxidant activity of the sample; Tocopherol(VE), Ax, Ax-γ-CD complex. Ax + VE mixture and Ax-γ-CD complex + VE mixture. The smaller total use of antioxidant weight (Ax and VE μg) to scavenge 0.1μmol of DPPH radical is, the larger antioxidant activity has. Ax-γ-CD complex + VE mixture is the best and it shows much more antioxidant activity than Ax only.
