Embodiment 1

[0031] A method for extracting fucoxanthin from sargassum, comprising the steps of:

[0032] A1. Pretreatment: Rinse the fresh sea wormwood with clean water, wash off the surface sediment particles and mucus, drain the surface water, and cut it into 0.3cm-sized crushed algae;

[0033] A2. Extraction: Weigh the chopped Sargassum algae, add absolute ethanol according to the ratio of material to liquid 1g: 10ml, mix well, put it into an ultrasonic extraction instrument for ultrasonic extraction; the ultrasonic power is set to 1500W, the initial temperature 20°C, extraction time 5min, repeat ultrasonic extraction twice;

[0034] A3, solid-liquid separation: the extract is subjected to solid-liquid separation by suction filtration;

[0035] A4. Concentration: put the separated extract into a rotary evaporator, and evaporate and concentrate the extract at a temperature of 40°C to obtain a crude fucoxanthin extract;

[0036] A5. Separation and purification: The obtained crude fucox...

Description

technical field [0001] The invention belongs to the field of fucoxanthin extraction technology, and in particular relates to a method for extracting fucoxanthin from sargassum. Background technique [0002] Fucoxanthin (Fucoxanthin), also known as fucoxanthin, is a fat-soluble carotene. The pigment is golden brown. It has a strong antioxidant effect because of its special allene carbon skeleton in its structure. , studies have shown that fucoxanthin has anti-acne, anti-tumor, anti-malarial, anti-inflammatory, anti-angiogenesis, anti-obesity and other pharmacological effects, and also protects human brain blood vessels, eyes, skin, bones, and liver. It has broad development prospects in the fields of medicine, food, cosmetics, nutrition and health care. In the current market, the sales price of products containing 1% fucoxanthin can reach 175 US dollars per kilogram. [0003] In nature, fucoxanthin mainly exists in various algae, marine phytoplankton and other animals and p...
