Abstract

The invention discloses a method for extracting a fucoxanthine crude product from sargassum horneri; the method mainly comprises the steps of pretreatment, suction filtration, ultrasonic leaching, extraction and the like. With the sargassum horneri as a raw material, the fucoxanthine is extracted, the whole extraction process is optimized, the process steps are simple, the operability is strong, the yield of the crude product is high, a theoretical basis is provided for industrialized production for extracting fucoxanthine from the sargassum horneri, and the method has great value for development.

Description

technical field [0001] The invention relates to a method for extracting fucoxanthin, in particular to a method for extracting crude fucoxanthin from copper algae. Background technique [0002] The copper algae (Sargassum horneri) has tall strains and luxuriant branches and leaves. It is the main contiguous large brown algae species in shallow seaweed fields in warm temperate seas of China. [0003] Fucoxanthin (fucoxanthin), also known as fucoxanthin and fucoxanthin, belongs to the xanthophylls in carotenoids, and is widely found in various algae, marine phytoplankton, aquatic shellfish and other animals and plants. Relevant studies at home and abroad have proved that fucoxanthin has the functions of anti-oxidation, anti-cancer, and increasing the content of DHA and ARA in mice. Fucoxanthin will have broad application prospects as drugs, health care products and skin care and beauty products. At present, most studies on fucoxanthin at home and abroad are based on kelp and ...
