Abstract
The invention belongs to biomedicine technical fields, and in particular to a kind of crispy gracilaria polysaccharide and its preparation method and application.The preparation method of the crispy gracilaria polysaccharide is the following steps are included: crisp river hedge is extracted after dehydrated alcohol is pre-processed and is dried using hot water, in triplicate, extracting solution merging obtains concentrate after being concentrated in vacuo, solution of trichloroacetic acid is added while stirring into concentrate, it is stood overnight at 4 DEG C, it is centrifuged off precipitating, obtain supernatant, then supernatant being adjusted to neutrality and carrying out alcohol precipitation to concentration of alcohol is 50~60%, it collects to stand after dehydrated alcohol oscillation washing is added after precipitating and be centrifuged, crispy gracilaria polysaccharide is made after dialysis freeze-drying.The present invention also provides application of the crispy gracilaria polysaccharide in terms of anti-inflammatory or anti-tumor chemotherapeutic medicine synergist.Crispy gracilaria polyoses producing method simple and stable of the present invention, the crispy gracilaria polysaccharide of preparation effect in terms of anti-inflammatory or anti-tumor chemotherapeutic medicine synergy is obvious, is suitble to promote and apply.
Description
Technical field
The invention belongs to biomedicine technical fields, and in particular to a kind of crispy gracilaria polysaccharide and its preparation method and application.
Background technique
Crispy gracilaria is a kind of large-scale economy class cultivating seaweed of Gracilaria, and main product is in southeast such as China Zhejiang, Fujian, Jiangsu
Coastal area, be mainly distributed at present Guangdong Province Nan'ao it is coastal cultivate successfully and can large area plantation.Fresh crispy gracilaria color
For aubergine or light red, plump succulence, matter is crisp, darkens after dry.Due to early stage crisp river hedge yield rareness always not by
Pay attention to, therefore it is seldom to the research of crisp river hedge both at home and abroad, it is continuously increased recently as the yield of crispy gracilaria, the work of crisp river hedge
The research of property ingredient and biological activity also gradually causes the concern of people.Studies have shown that crispy gracilaria rich in various active polysaccharide,
Phycoerythrin and the necessary nutrient of dietary fiber and human body etc. have immunoregulatory activity, antitumor, anti-oxidant, disease-resistant
The various biologicals such as poison activity and medicinal health effect, wherein active polysaccharide attracts as a kind of effective component of high-efficiency low-toxicity
The extensive concern of researchers.Therefore how from crispy gracilaria polysaccharide component is easily effectively extracted with regard to particularly critical.It is more
The extracting method that carbohydrate content generallys use includes Hot water extraction, diluted acid and diluted alkaline extraction method, and new process includes enzyme process, ultrasound
Wave auxiliary, microwave-assisted extraction and ultrafiltration etc..
Such as Ju Yaoyao et al. is optimized by extraction process of the response surface experiments to crispy gracilaria polysaccharide (GCP), and
Its inhibiting effect to tumour cell is had studied, for the extracting method used for conventional Hot water extraction, the crispy gracilaria of preparation is more
Sugar can effectively inhibit the production of tumour cell, but the property of the crispy gracilaria polysaccharide is unstable, and response surface optimization is tested
Complex process.The crispy gracilaria polysaccharide extracted is further researched and developed into Pharmaceutical Polysaccharides or health care product polysaccharide, is beneficial to
The complex treatment and rehabilitation of inflammation and tumour patient, while making that the poison of the common anti-inflammatory anti-tumor drug of cell toxicant class is not secondary
With therefore, crispy gracilaria polysaccharide is worth further research and development, improves the economic use value of crispy gracilaria.
Based on current crispy gracilaria polysaccharide, there is the scarce of complex process, stability difference and repeatability difference in terms of preparation
