The synergism of the pigment
and Vc showed significantly higher DPPH.

activity than only the pigment of the same concentration
and the activity of the pigment in 0.5 mg mL-1 with
Vc was higher than that of 0.1 mL Vc in 0.1 mg mL-1,
but, if only the pigment was used, the activity of the
pigment in 5 mg mL-1 was more than that of Vc. So
synergism of the pigment with Vc could significantly
heighten DPPH.
