Abstract

The invention relates to an anthocyanidin made from Vaccinium uliginosum L. and separation and purification methods thereof, which belong to the technology field of active component extraction and purification and functional food development. The content of anthocyanidin in Vaccinium uliginosum L. is 29.8-40%, wherein the content of malvidin accounts for 4.68-5.48% of the anthocyanidin; and antioxidant activity of the anthocyanidin is as 7.8-15 times as that of Vc. The preparation method includes pre-treating raw material, cold soaking and concentrating, purifying and concentrating, and freeze dying. The ultrasonic and microwave-assisted cold soaking method is employed for separation, and an AB-8 macroporous resin static-dynamic combined absorption purification method is employed. The invention provides an environmental friendly, high-efficiency and low-cost separation and purification technology of anthocyanidin made from Vaccinium uliginosum L., which maintains product bioactivity such as antioxidant property of product and ideal separation effect, establishes the basis for wide utilization of abundant resource of Vaccinium uliginosum L. and industrialized development promotion of a series of Vaccinium uliginosum L. health food, and embodies great economic benefit and social benefit in deep processing of the Vaccinium uliginosum L.
