Abstract

The invention discloses a Lycium ruthenicum anthocyanin and a preparation method thereof. The preparation method comprises the following steps: preparing a Lycium ruthenicum anthocyanin powder; extracting the Lycium ruthenicum anthocyanin; and purifying and freeze-drying the Lycium ruthenicum anthocyanin. The Lycium ruthenicum anthocyanin prepared in the invention has good ability to remove DPPH free radicals and hydroxyl free radicals, and has influences on fat accumulation, lipid metabolism and insulin tolerance of obese mice.

Description

technical field [0001] The invention belongs to the technical field of natural product development, and in particular relates to a black wolfberry anthocyanin and a preparation method thereof. Background technique [0002] Anthocyanidin, also known as anthocyanin, is a kind of water-soluble natural pigment widely present in plants in nature, and belongs to flavonoids. Anthocyanins have the application value of anti-blood lipid, hypoglycemic, anti-oxidation, immune regulation, anti-aging, prevention and treatment of cardiovascular disease, arteriosclerosis, tumor drug. Similar to flavonoids in the molecular mechanism of scavenging free radicals, it can scavenge a variety of oxygen free radicals in vivo and in vitro, and can promote and activate various antioxidant enzymes in the body; the polyphenol structure can complex metal ions to prevent such Metal ions with redox activity catalyze to accelerate the generation of free radicals, and finally enhance their antioxidant effe...
