Description
Technical field
The present invention relates to the edible mushrooms extracting method of a kind of enrichment mineral element, it is specifically related to the fine pore fungi total triterpene extracting method of a kind of birch.
Background technology
The fine pore fungi (Inonotusobliquus (Ach.exPers.) Pil á t) of birch also claims Phaeopoms obliquus, Chaga, belong to Basidiomycotina, Hymenomycetes, Aphyllophorales, Hymenochaetaceae, in foreign language datum, it often occurs with formal name used at school Inonotusobliquus. The fine pore fungi sclerotium of birch is warty, without handle, and surface black gray expandable, inner yellowish-brown, old rear surface drastic crack, hard, more crisp time dry. Have and strengthen immunity, the curative effects such as the prevention sick urine of sugar. As a kind of main active ingredient of the fine pore fungi of birch, three terpenes can be used for the prevention and therapy of diabetes, malignant tumour, cardiovascular disorder, hepatopathy and acquired immune deficiency syndrome (AIDS). In triterpene compound, trochol and derivative thereof have anti-treating leukemia, the special efficacies such as anti-hiv activity and anti-melanocyte tumor activity. Therefore, the fine pore fungi of birch has great pharmacy value. Mineral element is the important component part of humans and animals body, has important physiological function. The mineral element major part of enrichment in edible mushrooms exists with organic, and good stability, and wherein the mineral element of major part organic is all combined with the biomacromolecule such as protein, polysaccharide, and facilitates absorption and the utilization of mineral element. At present to the still few report of nutrition assay after the fine pore fungi triterpenoid extraction process of birch and enrichment mineral element, traditional triterpenes components extracting method: extraction process, semi-bionic extraction, chemical derivatization, ultrasonic circulation techniques etc. easily cause three terpene degradeds, supercritical fluid extraction becomes a kind of new extraction and separation technology in recent years, has the advantages such as composition activity and no solvent residue of remaining valid. But equipment is complicated, running cost height, extracts scope narrow, is not thus widely used.
Summary of the invention
The present invention is directed in above-mentioned technology the deficiency existed, it is provided that the fine pore fungi total triterpene extracting method of a kind of birch, solves energy consumption when extracting in prior art big, production cost height, the problem that extraction yield is low.
The technical solution used in the present invention is as follows:
An extracting method for the fine pore fungi total triterpene of birch, its concrete operation steps is as follows:
Step 1, pre-treatment: the fine pore fungi mycelia of birch under 60-80 DEG C of condition, dry 10-16 hour;
Step 2, broken wall: pulverized by fine for above-mentioned pretreated birch pore fungi mycelia broken wall, cross 200 order sieves, add 95% ethanol, and the mass ratio of 95% ethanol and mycelia is 30-50:1, is mixed with suspension, soaks 24h;
Step 3, ultrasonication: by fine for above-mentioned birch pore fungi suspension ultrasonication, 60-80 DEG C, power 400W, time 10-20min;
Step 4, concentrating under reduced pressure: the suspension after above-mentioned ultrasonication is evaporated to AmL, obtain AmL concentrated solution; Under 13000-16000r/min, 0-5 DEG C of condition, centrifugal 8-15min, gets supernatant liquor, adds 95% ethanol and be settled to AmL in supernatant liquor;
The absorption of step 5, total triterpene and purifying: with the flow velocity of 2BV/h, the liquid after above-mentioned fixed appearance being crossed macroporous adsorbent resin column chromatography, with 80% ethanol elution, collects the solution eluted after variable color, the solution eluted is extracting substance.
It is an advantage of the current invention that: the present invention takes broken wall to pulverize a kind of wall-breaking method hocketed with ultrasonic-assisted extraction, impels the high temperature that simultaneously avoids that cell breaks completely that raw material being said, the nutritive loss caused, effective constituent destroy serious detrimentally affect. The fine pore fungi total triterpene of ultrasonic-assisted extraction birch, mechanical effect also accelerates the fragmentation of cell walls, promotes the Fast Stripping of total triterpene active substance in born of the same parents. Compared with tradition Polyose extraction, broken wall pulverize and and ultrasonic-assisted extraction effectively combine, have that energy consumption is low, total triterpene extraction yield height, the feature that production cost is low. By broken wall combining ultrasonic ripple extracting method of the present invention, the fine pore fungi total triterpene extraction yield of birch is 1.15～1.72 times of traditional extraction process.
Accompanying drawing explanation
Fig. 1 is the process flow sheet that the present invention extracts the fine pore fungi total triterpene of birch.
