Anthocyanins, proanthocyanidins and proanthocyanidins are water-soluble natural pigments widely present in plants, and the main differences between the three are as follows:

1. Anthocyanins: Anthocyanidins are secondary metabolites of plants, which are water-soluble pigments and flavonoid compounds.

2, former anthocyanins: former anthocyanins (PCA) is a family of bioflavonoids, a polyphenolic.

3, proanthocyanidins: proanthocyanidins (grape seed extract) is a new type of efficient antioxidant.

Second, the characteristics of different

1, anthocyanins: can change color with the acidity of the cellular fluid. The cellular fluid is acidic is reddish, the cellular fluid is alkaline is bluish.

2, proanthocyanidins: proanthocyanidins are non-toxic, water-soluble, and have strong antioxidant properties.

3, proanthocyanidins: so far found the most potent free radical scavenger, has a very strong in vivo activity, to protect lipids from peroxide damage.

Three, the role of different

1, anthocyanins: anthocyanins are the most effective antioxidants found in mankind today, but also the most potent free radical scavenger, anthocyanins antioxidant performance than VE 50 times higher than VC 20 times higher.

2. Proanthocyanidins: the most efficient antioxidant and free radical scavenger to date.

3, proanthocyanidins: a strong antioxidant, free radicals, can effectively eliminate superoxide anion radicals and hydroxyl radicals, but also involved in the metabolism of phosphoric acid, arachidonic acid and protein phosphorylation, protection of lipids do not occur peroxidation damage; is a powerful metal chelator.
