Abstract

The invention discloses a blackberry anthocyanidin extracting method, a blackberry anthocyanidin extract and application of the blackberry anthocyanidin extract. The extracting method comprises the following steps: unfreezing frozen blackberry, and conducting homogenization to obtain a blackberry pulp for standby use; adding water or ethanol of any concentration, and adopting microwave-assisted extraction to obtain an extracted solution; conducting centrifugation on the extracted solution, and collecting a supernatant to obtain the blackberry anthocyanidin extract. The microwave-assisted extraction method is adopted, influences on the extraction ratio and the antioxidant activity by a plurality of factors are comprehensively considered, and the obtained extraction process is scientific and reasonable, simple to operate, low in cost, and suitable for industrialized mass production. According to the blackberry anthocyanidin extracting method, the extraction efficiency is improved, the yield of blackberry anthocyanidin reaches about 2.18 mg / g, and the characteristics that extraction equipment is simple, the operation is convenient, the cost is low, the efficiency is high, and the yield is high are achieved; the adopted solvent is safe and environmentally friendly; the extract can be used for medicines, cosmetics or health products.

Description

technical field [0001] The invention relates to a method for extracting blackberry anthocyanins and its product and application, belonging to the technical field of plant extraction. Background technique [0002] Blackberry (Blackberry), Rosaceae (Rosaceae) Rubus (Rubus) shrubs, mainly native to the northern temperate zone of the Old and New World, especially rich in eastern North America and the Pacific coast, common sprouting forest and hedge plants in the British Isles and Western Europe, with relatively large varieties It has a wide range of cultivation and abundant resources. Because fresh blackberries not only have a sweet taste, but also contain a lot of vitamins, amino acids, mineral elements, trace elements, inorganic salts, pectin, flavonoids, organic acids, phenols, crude protein and sugars and other nutrients. It has the functions of food and medical care, and is loved by the masses. Blackberry has the effects of calming the nerves, nourishing the skin and impr...
