Abstract
The invention discloses a preparation method of ginger extract. The preparation method is characterized by comprising the following steps of: a, preparing the ginger, cleaning, slicing, drying until the water content is less than 5%, crushing to obtain the ginger powder; b, refluxing and extracting the ginger powder obtained in the step a for 1-3 hours by using 60-70% ethanol, wherein the extracting is performed for 2-5 times, combining the extracting solutions to obtain the primary extracting solution; c, adsorbing the primary extracting solution obtained in the step b by using macroporous resin, and respectively eluting the macroporous resin by using 70-80% ethanol, 50-60% ethanol and 30-40% ethanol, combining the eluting solutions, standing for 1-3 hours, filtering to obtain the rough extracting solution; d, concentrating the rough extracting solution obtained in the step c till 20-30% of the original volume, standing for 1-2 hours, filtering, and drying to obtain the finished product ginger extract. The preparation method disclosed by the invention has the advantages that the prepared extract is high in effective component, low in energy consumption, simple in process step and easy to operate, and the application prospect is wide.
Description
Technical field
The present invention relates to Rhizoma Zingiberis Recens extract, relate in particular to a kind of preparation method of Rhizoma Zingiberis Recens extract.
Background technology
The Chinese medicine Rhizoma Zingiberis Recens is the bright rhizome of zingiber, and nature and flavor suffering, temperature are returned lung, spleen, stomach warp, have effects such as the cold expelling of inducing sweat, warming middle-JIAO to stop vomiting, preventing phlegm from forming and stopping coughing, cures mainly anemofrigid cold, gastrofrigid vomiting, cold-phlegm cough.Be used for the control motion sickness, and side effect is not obvious.But Rhizoma Zingiberis Recens juice and Rhizoma Zingiberis powder are all unstable, are difficult to be prepared into stable, dosage form easily.Preparation technology's effective component extraction rate of Rhizoma Zingiberis Recens extract is low in the prior art, and consumes energy is big, the loaded down with trivial details difficulty of processing step, application prospect narrow sense.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The preparation method that the purpose of this invention is to provide a kind of Rhizoma Zingiberis Recens extract.
The technical solution used in the present invention is:
A kind of preparation method of Rhizoma Zingiberis Recens extract may further comprise the steps:
A: prepare the raw material Rhizoma Zingiberis Recens, clean, section is dried to water content under 5%, pulverizes, and gets the Rhizoma Zingiberis Recens powder;
B: with the Rhizoma Zingiberis Recens powder of gained among the step a alcohol reflux 1-3h with 60-70%, extraction time is 2-5 time, merge extractive liquid,, extracting solution at the beginning of getting;
C: with the first extracting solution macroporous resin adsorption of gained among the step b, use the ethanol of ethanol, 30-40% of ethanol, the 50-60% of 70-80% respectively to the macroporous resin eluting then, merge eluent, leave standstill 1-3h, filter, get crude extract;
D: the crude extract of gained among the step c is concentrated into the 20-30% of original volume, leaves standstill 1-2h, filter, drying gets the finished product Rhizoma Zingiberis Recens extract.
Rhizoma Zingiberis Recens is cut into slices to 1-5mm among the described step a.
Baking temperature is 30-40 ℃ among the described step a.
Drying means is vacuum drying or cold drying in the described steps d.
Advantage of the present invention is: the extract effective component content height of preparation, and consumes energy is low, and processing step is simple to operation, and application prospect is very wide.
