[0002] Proanthocyanidins are a class of polyphenolic polymers widely present in plants. Since the French professor Jacques Masquelier first extracted proanthocyanidins from the bark of Mediterranean pine in 1951, people have continuously discovered new resources rich in proanthocyanidins in nature, and analyzed and identified their composition and structure. Modern biology and pharmacology have proved that proanthocyanidins are non-toxic, non-carcinogenic, non-distorting, and non-allergic. damage to the body, thereby reducing the occurrence of various diseases caused by the destructive effect of free radicals, such as reducing the incidence of cancer, coronary heart disease, retinopathy caused by diabetes and other diseases; reducing all...
