5. Benefits of Black Bean Extract
The main active ingredients of Black Bean Extract, have many unique effects as below:
5.1 Antioxidant effect
The main component of black bean skin extract is anthocyanin, and the main component of anthocyanin is cyaniding-3-glucose, which is abbreviated as C3G. The study found that C3G can produce metabolites with the ability to inhibit oxidation and protocatechuic acid that can capture free radicals when it is stored in free radical generator (AMVN). Therefore, it is believed that C3G has a dual antioxidant effect, and C3G has the ability to significantly prevent active oxygen species (peroxide free radicals and light free radicals) from breaking the super helical DNA chain and inhibit the oxidative modification of human low-density lipoprotein.
5.2 Effect on the Cardiovascular System of Black Bean Peel Extract
Black bean anthocyanins can be used as drugs to regulate cardiovascular disorders. Black bean skin extract can also reduce the content of cholesterol in the liver and improve the activity of glutathione peroxidase in serum and liver. The mechanism of black bean skin extract to reduce the formation of AS plaque in rabbit aorta may be to improve lipid metabolism and antioxidation.

5.3Inhibition of diabetes
Anthocyanins can inhibit hyperglycemia induced by high fat and high sucrose, and make hyperinsulinemia completely return to normal; Cyanin-3-O-glucoside can reduce the production of reactive oxygen species in 3T3-Lla adipocytes, thereby improving H2O2 or TNF in a dose-dependent manner- α Induced insulin tolerance; It can reduce the expression of retinol binding protein in type II diabetes rats, thereby improving hyperglycemia and insulin sensitivity, thereby improving the symptoms of diabetes.
