Abstract

The invention relates to the field of biotin extraction and in particular provides a method for extracting biotins in sea-buckthorn and biotins obtained by adopting the method. The method for extracting biotins in sea-buckthorn comprises the following steps: performing enzymolysis on the sea-buckthorn with cellulase, performing ultrasonic wall breaking on the sea-buckthorn, and sequentially filtering, centrifuging and adsorbing the samples subjected to enzymolysis and ultrasonic wall breaking, thereby obtaining the biotins. According to the method disclosed by the invention, the sea-buckthornis subjected to enzymolysis with cellulase and then subjected to auxiliary wall breaking by adopting ultrasonic waves, the method disclosed by the invention has high extraction rate compared with a single enzyme extraction method, and has high safety compared with an organic solvent co-extraction method, and impurities in the samples are removed by filtration, centrifugation and adsorption so as to obtain the biotins with high purity.

Description

technical field [0001] The invention relates to the field of biotin extraction, in particular to a method for extracting biotin from seabuckthorn and biotin obtained by the method. Background technique [0002] Seabuckthorn is a deciduous shrub, which is characterized by drought tolerance, wind and sand resistance, and sand-fixing effect. Seabuckthorn is widely planted in Northwest China for desert greening, bringing good economic and sociological benefits to local social and economic development. value. Biotin, also known as vitamin H and coenzyme R, is a water-soluble vitamin and also belongs to the vitamin B family, B7; it is a necessary substance for the synthesis of vitamin C, an indispensable substance for the normal metabolism of fat and protein, and is a kind of maintenance of human body. Nutrients necessary for healthy growth, development and normal body function. [0003] Seabuckthorn contains considerable amounts of vitamins, including targeted components such a...
