Physical and Chemical Properties | from grape seed |
Background | Proanthocyanidins (PC) are a large class of polyphenolic compounds that widely exist in plants, with strong antioxidant, eliminate the role of free radicals, can effectively eliminate superoxide anion free radicals and hydroxyl radicals, but also involved in phosphoric acid, arachidonic acid metabolism and protein phosphorylation, protect lipids from oxidative damage; is a powerful metal chelating agent, can chelate metal ions, the formation of inert compounds in the body; Protection and stability of vitamin C, contribute to the absorption and utilization of vitamin C. Proanthocyanidins are widely distributed in the skin, Shell, seed, core, flower and leaf of many plants. |
biological activity | Procyanidol B4 ((-)-Procyanidin B4) is a flavanol isolated from Litchi chinensis. Has anti-inflammatory properties. |
Use | for content determination/identification/pharmacological experiments and other pharmacological effects: strong antioxidant activity |
