Description
Technical field
The present invention relates to a kind of acquisition methods of natural pigment.
Background technology
Pigment is widely used in the fields such as foodstuffs industry, bionic food, medicine and pharmacology, makeup, high-grade feed, and pigment is divided into synthetic food color and natural pigment.
Synthetic food color refers to take the pigment that coal tar makes as raw material, and it is of a great variety, as Xanthones pyridine based dye, anthraquinone based dye, azo based dye, quinoline based dye etc.The character of synthetic food color is conventionally more stable, has good tone, look valency, solvability and tinting strength, and while production cost is low, product with stable quality, thereby uses comparatively extensive.Yet large quantity research is found in recent years, and synthetic food color not only can not, for human body provides nutritive substance, also can work the mischief to HUMAN HEALTH.
Natural pigment refers to the pigment of natural resource such as deriving from animals and plants, microorganism.According to the difference of its chemical structure, can be divided into: 1. pyrrole derivative, as chlorophyll, protoheme and Choline etc.; 2. isoprene derivatives, as carotenoids etc.; 3. Polyphenols derivative, as anthocyanidin, words flavine, catechin, tannin etc.; 4. ketones derivant, as monascorubin, curcumine etc.; 5. naphthoquinone derivatives, as shellac color, cochineal etc.; According to the difference of its dissolving properties, natural pigment can also be divided into water colo(u)r and fat-soluble pigment.
Comparing natural pigment security with synthetic food color good, also with nutrition and pharmacological action, is that desirable pigment is selected.Fungi pigment is a kind of of natural pigment, the fungi dye compound of finding at present comprises quinones, acids, heterocycle and nitrogenous compound, wherein take quinones as main, this compounds has important pharmacologically active, for example violacein by numerous scholars report there is pain relieving, reduce phlegm and internal heat, anticancer effect.And animal and plant raw material has unrivaled advantage with fungi production pigment relatively, it is with short production cycle, output is high, be not subject to spatio-temporal restriction, is convenient to suitability for industrialized production, simultaneously the not impact of climate and environment.Therefore, fungi has huge potentiality to be exploited as the generation resource of pigment.
Red fungus (Trametes cinnabarina (Jaxq.) Fr.var.sanguine) is the aperture mutation of red bolt bacterium (Trametes cinnabarina (Jacq.:Fr.) Fr.), is under the jurisdiction of Basidiomycotina, Hymenomycetes, Aphyllophorales, polyporaceae, trametes.Red fungus is born on pin, deciduous tree deadwood, often growth in flakes in groups.In China, be mainly distributed in the provinces and cities such as Heilungkiang, Yunnan, Guizhou, Guangdong and Chongqing.Red fungus has the effects such as anti-inflammatory, antipruritic, removing toxic substances, myogenic, pleasant, removing damp-heat, hemostasis; Inhibiting rate to ehrlich carcinoma and small white mouse sarcoma 180 is 90%, cancer cells is also had to restraining effect simultaneously.In addition, red fungus also contains polyporin, thereby Gram-negative and positive bacteria are all had to restraining effect.Red fungus contains red natural pigment---cinnabarin (cinnabarine), cinnabarin also has pharmacological action, can rabies poison (

Because fungi pigment stability is poor, in addition traditional extraction technology, as milling process, comminuting method, circumfluence method, organic solvent extraction method, there is complicated operation, production cost is high, product purity is low, have dissolvent residual, heat-sensitive component is destroyed etc., cause cinnabarin look valency low, hindered applying of cinnabarin.
Summary of the invention
The present invention is in order to solve the low problem of existing cinnabarin look valency, and the acquisition methods of a kind of high look valency cinnabarin providing.
High look valency cinnabarin obtains according to the following steps:
One, the red fungus mycelia after rejuvenation is transferred in PDA liquid nutrient medium, the condition bottom fermentation that is 140r/min at 28 ± 1 ℃, rotating speed is cultivated 10～15 days, then removes by filter mycelium;
Two, resin pre-treatment: the alcohol immersion resin 24h that is 95% by concentration, then with wet method dress post, resin is packed into chromatography column, adverse current is washed post, the washing with alcohol resin that is 95% by concentration again, flow velocity is 2 times of column volumes per hour, until that elutant is mixed with distilled water 1:5 is not muddy, then uses distilled water washing resin, flow velocity is 2 times of column volumes per hour, until elutant does not have ethanol taste;
Three, will add in step 1 filtrate and adsorb through pretreated resin, after being uniformly mixed 12～14h, resin is packed in chromatography column, with 2 column volumes of 15mL/min speed washing, collect elutriant, and then take the ethanol elution that the speed of 15mL/min is 70% by concentration, to the A of ethanol eluate
416value is less than 0.5 and stops collecting elutriant;
