Embodiment Construction

[0008] One of the most preferred embodiments of the present invention is: get 100 kilograms of artificially cultured fresh kelp, rinse with fresh water to remove impurities and foreign matter, then use a shredder to chop the clean kelp, add about 40 kg of absolute ethanol until the ethanol concentration is 70%; use a beater to beat the algae into a slurry, wash the filter residue twice with 2kg of 70% ethanol, combine the filtrate and stir and extract for 24 hours; use a large evaporator at 60°C to remove water, ethanol and pigment (the pigment usually precipitates on glass) At this time, a large amount of precipitated salt can be seen, and then the salt is removed by suction filtration to obtain a clear crude extract. Place the container containing the crude extract in an ice-water bath at a temperature of -2°C, and slowly add excess Reynolds' salt solution into the container until the precipitate is completely formed. After filtering, 4.6 kg of the product auxin of the prese...

Abstract

The present invention relates to an extracting process of biochemical matter and is an extraction of betaine and its analog from seaweed. The technological scheme has a technological process including six steps, that is, washing fresh seaweed to remove impurities, adding absolute alcohol before pulping and filtering, extraction, evaporation to remove water, alcohol and pigment, centrifugation to separate salt and obtain crude liquid extract, and adding excessive fulminate for precipitation. The present invention has the advantages of simple technological process, low extraction cost, comprehensive utilization of seaweed resource, etc.

Description

technical field [0001] The invention discloses an extraction process of seaweed auxin (betaine and its analogues), which belongs to the technical field of preparation of seaweed biochemical substances, and is used for extracting natural fertilizers from seaweed that can be used to promote the growth of crops and increase the yield Amino acid or imino acid derivatives for additives. Background technique [0002] In the prior art, it has long been known through research that betaine is a derivative of amino acid or imino acid, contains fully methylated pentavalent nitrogen, and exists in the form of open ring and closed ring structure. It has also long been known that this substance can be used as a growth agent for plants. For example, as early as 1962, Wheeler believed that glycine betaine (quaternary ammonium compound) in sugar beet is a plant growth regulator and has a high level of cytokinin-like activity. At the same time, a large number of studies at home and abroad h...
