Description
Technical field
The invention belongs to edible mushrooms to extract field, more particularly to a kind of preparation method of Hericium erinaceus ethanol extract.
Background technology
China is raw material for treating stomach trouble drug about more than 100 kind using Hericium erinaceus at present, helicobacter pylori
(Helicobacter pylori) is a kind of aerobic-type Gram-negative bacteria, and a large amount of clinical researches show that H.pylori can draw
Play the stomach trouble such as chronic gastritis, peptic ulcer, gastric cancer, gastric mucosa.
Hericium erinaceus (Hericium erinaceus) is applied to gastrointestinal disease treatment with distinct distinct Chinese characteristics, in clinic
On be widely used for treating chronic gastritis, the diseases such as gastroduodenal ulcer, have accumulated a large amount of clinical experience and data.Last century
The success of Hericium erinaceus artificial cultivation is tamed in the sixties, China where Shanghai City academy of agricultural sciences edible mushroom first.The seventies is from civil understanding
Have to Hericium erinaceus and mend stomach function, starts from hedgehog hydnum syrup and clinical trial is made to duodenal ulcer patients, obtain good control
Therapeutic effect.
The method of currently used extraction Hericium erinaceus is mainly the water extract-alcohol precipitation of routine, but the Hericium erinaceus being obtained by carries
It takes object to inhibit helicobacter pylori active constituent few, practical application can not be put into.

10 times or more are improved, adsorption activity effect is preferable.
Embodiment 4
The elution effect of different volumes score ethyl alcohol
(1) static elution
Take resin HPD-100, the AB-8 adsorbed, after the distillation water elution of 3 times of bed volumes, successively with 10%,
30%, each 4 times of bed volumes of 50%, 70%, 90% and 100% ethanol solution set constant-temperature table 110rpm, 25 DEG C, the condition of 2h
Lower carry out gradient elution, color is shallow by being deep to, be washed till respectively it is colourless, collect eluent, be concentrated into cream.Condensed cream dilutes certain
Multiple surveys the bacteriostatic activity to H.pylori.
(2) dynamic desorption
Hole resin fills pillar (blade diameter length ratio 1:8), after the distillation water elution of 3 times of bed volumes, successively with 10%, 30%,
50%, each 4 times of bed volumes of 70%, 90% and 100% ethanol solution carry out gradient elution, Hericium erinaceus aqueous extract sample concentration
For 0.1kg/L, resin applied sample amount is 1kg/1L, and flow velocity is washed till colourless, Fractional Collections eluent respectively for 1.5mL/min, and dense
Shorten cream into.Bacteriostatic activity of certain multiple measurement to H.pylori is diluted with condensed cream.
(3) experimental result
The result shows that two kinds of elution requirements are identical to the effect of bacteriostatic activity, it is all higher than using MIC when distillation water elution
10mg/mL, and use 10%, 30%, 50% ethanol elution when static state elution and dynamic desorption liquid MIC 5-10mg/mL it
Between;The poor MIC of eluent bacteriostatic activity obtained using HPD-100 and 10%-50% ethanol elutions is all higher than 2.5mg/mL, and
70%, the MIC of eluent obtained after 90% and 100% elution is respectively 0.25-0.5mg/mL, 125-250mg/mL,
0.25mg/mL, wherein the extract after 90% ethanol elution inhibits the minimum 125- of minimum inhibitory concentration of H.pylori ATCC
250mg/mL.As a result show that the active constituent for inhibiting helicobacter pylori is concentrated mainly on 70%, 90%, 100% ethanol elution
In liquid, in the ethyl alcohol stripping liquid of 70%, 90%, 100% 3 kind of volume fraction, 90% ethyl alcohol to H.pylori bacteriostatic activities most
It is good, and the eluent fungistatic effect difference obtained after 90% ethyl alcohol, 100% ethanol elution is little.
Embodiment 5
It is external to inhibit helicobacter pylori confirmatory experiment
The hedgehogt fungus crude extract medicinal extract that embodiment 1 is prepared is configured to the water extract solution of 100mg/ml, then
Carry out following method extraction.
(1) HPD-100 resins extract:It is added in the pretreated macroreticular resin HPD-100 to lysate of 5L and adsorbs for 24 hours,
Period need to stir frequently, remove supernatant, the macroreticular resin after being adsorbed, and the macroreticular resin after absorption is filled pillar (blade diameter length ratio 1:
8) gradient desorption, is carried out with distilled water, each 4 times of bed volumes of 50% ethanol solution successively, flow velocity is that 1.5mL/min is washed till respectively
It is colourless, then with 95% ethanol elution and it is condensed into cream.
(2) experimental result
The five kinds of pylorus spirals of Hericium erinaceus ethanol extract pair extracted using HPD-100 macroreticular resins and 95% ethyl alcohol
The minimum inhibitory concentration of bacillus is respectively 0.5-1mg/mL (Helicobacter pylori ATCC), 0.125-0.25mg/mL
(Helicobacter pylori SS1)、0.5-1mg/mL(Helicobacter pylori W2504)、1mg/mL
(Helicobacter pylori DXF) and 0.5mg/mL (Helicobacter pylori 78);And five kinds of water extract pair
The minimum inhibitory concentration of helicobacter pylori is respectively 2.5-5mg/mL (Helicobacter pylori ATCC), 5mg/mL
(Helicobacter pylori SS1)、5mg/mL(Helicobacter pylori W2504)、2.5-5mg/mL
(Helicobacter pylori DXF) and 5mg/mL (Helicobacter pylori 78).Comprehensive analysis uses HPD-
100 and 95% the obtained activity of Hericium erinaceus ethanol extract of ethanol elution improve 20 times.
(3) it discusses
The present embodiment takes antibacterial component of the method that activity tracks to separation hedgehog hydnum solid fermentation mycelia to H.pylori
Be enriched with, in four kinds of macroreticular resins of selection, HPD-100 macroreticular resins to the activated adoption ability of hedgehog hydnum solid mycelia most
It is good, and it is 0.5-1mg/mL, activity to be determined that active material is concentrated mainly in 50-95% ethanol eluates minimum bacteriostatic activity
20 times are improved than water extract.This is adsorbed with effect active material to studying HPD-100 macroreticular resins later to hedgehog hydnum solid mycelia
Technical study in play basic research, and there is macroporous absorbent resin adsorption separation method consumption of organic solvent can return less
Many advantages, such as receiving, can be used repeatedly, regenerating simply, reduce cost, is a kind of efficient separation purifying technique, can use
The concentration and separation of active ingredient and big industrial production in Hericium erinaceus.
