Extracting process for seaweed plant growth hormone

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...
