Cantharidin yellow is a kind of natural pigment with great potential antioxidant. It has the ability of quenching active oxygen and scavenging free radicals. Its ability to quench active oxygen and scavenging free radicals is second only to astaxanthin. It is β-carrot It is nearly twice as much as vitamin E and 50 times as much as vitamin E. It is also known as super vitamin E.

Function:
Cantharidin is a carotenoid that is not a vitamin A source. Its chemical structure is composed of 4 isoprene units connected by conjugated double bonds, and two isoprene units at both ends form a six-membered ring structure. The C4 and C4' positions of the membered ring structure contain the oxygen functional group ketone group. In addition to being used as a pigment in animal coloring and cosmetics, cantharidin yellow has a variety of physiological functions in the animal body. application
