Flavonoids of sea-buckthorn are the essential components of sea-buckthorn. Under normal circumstances, less than 15 grams of flavonoids can be extracted from every 3 tons of sea-buckthorn whole fruit, which is extremely precious. Flavonoids of sea-buckthorn contain quercetin, isorhamnetin, kaempferol and other active ingredients, which can lower blood pressure, reduce blood lipids, reduce blood viscosity, enhance vascular elasticity, anti-atherosclerosis and other functions, and is the "Nemesis" of cardiovascular and cerebrovascular diseases. 1. The fall hematic fat As an antioxidant in vivo, flavonoids of sea-buckthorn can inhibit the formation of oxidized low-density lipoprotein, increase the synthesis of high-density lipoprotein, improve the activity of lecithin cholesterol acyltransferase, reduce LDL cholesterol and increase HDL cholesterol, so as to achieve the purpose of lowering blood lipid. 2. Anti-atherosclerosis Generally speaking, there are two reasons for the formation of atherosclerosis: one is the damage of the blood vessel wall; The second is high blood fat. Sea-buckthorn flavonoids, as antioxidants in the body, can remove free radicals in the blood and reduce the erosion and damage of free radicals to vascular walls. At the same time, flavonoids of sea-buckthorn can reduce the synthesis of low density lipoprotein and increase the synthesis of high density lipoprotein, thus reducing blood lipid.
