Abstract
The invention relates to an extraction method for rhizoma alpiniae officinarum volatile oil. The extraction method includes the following processing steps: the rhizoma alpiniae officinarum is cut into pieces and smashed by a plant tissue smashing method; the smashed rhizoma alpiniae officinarum is extracted by adopting microwaves, and after filtration, filtrate is concentrated until alcohol taste does not exist; the concentrate is subject to steps such as organic solvent extraction and concentration, and thereby the rhizoma alpiniae officinarum volatile oil is obtained. The process of the extraction method is simple, reaction conditions are mild, and compared with a conventional extraction method, the extraction method has the advantages of preventing bioactive substances from being degraded by heat under high temperature and causing the loss of active ingredients.
Description
Technical field
The present invention relates to a kind of extracting method of Rhizoma Alpiniae Officinarum volatile oil, belong to active ingredient of natural product extraction and separation technology field.
Background technology
Rhizoma Alpiniae Officinarum is the dry rhizome of zingiberaceous plant Rhizoma Alpiniae Officinarum.Taste is pungent, hot in nature, returns spleen, stomach warp, has warming stomach for dispelling cold, the effect of the pain relieving that helps digestion, for coldness and pain in the epigastrium, gastrofrigid vomiting, belch acid regurgitation.Rhizoma Alpiniae Officinarum and extract thereof have the multiple pharmacological effect such as hypoglycemic, anti-oxidant, anticancer, antibacterial, immunological enhancement.Volatile oil is one of main active ingredient of Rhizoma Alpiniae Officinarum, has analgesia preventing or arresting vomiting double pharmacological action.Rhizoma Alpiniae Officinarum volatilization main body of oil have eucalyptol, Methyl cinnamylate, allylguaiacol, 4-phenyl isobutyl alcohol ketone, phenylpropionaldehyde,
α-firpene, 4-vinylcarbinol phenol, palmitinic acid,
β-guaiene etc.
At present, the extracting method about Rhizoma Alpiniae Officinarum volatile component mainly contains: steam distillation and supercritical fluid extraction etc., the equal Shortcomings of these methods.Though steam distillation method is classical, technical maturity, high temperature easily causes heat-labile compound decomposition, and yield is not high, and loss is large; Though and supercritical fluid extraction environmental protection and extraction yield is higher, complex operation step, apparatus expensive, maintenance difficult, also easily introduce plastic plasticizer and extract the compositions such as wax, being difficult to realize suitability for industrialized production.
In order to overcome above-mentioned technical disadvantages, the present invention adopts plant tissue crush method process raw material, then in conjunction with microwave assisted extraction Rhizoma Alpiniae Officinarum volatile oil, has the advantage that technique is simple, reaction conditions is gentle, yield is high, cost is low, be suitable for suitability for industrialized production.This method now has no relevant report.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of extracting method of Rhizoma Alpiniae Officinarum volatile oil is provided.
The present invention includes following steps:
A. being cut into small pieces by Rhizoma Alpiniae Officinarum, pulverizing, wherein add the ethanolic soln of 50 ~ 60% of Rhizoma Alpiniae Officinarum weight 1 ~ 2 times by plant tissue crush method, is extract 1 ~ 3min under the condition of 1000 ~ 3000r/min at rotating speed;
Material in step a takes out by b, is placed in microwave device, adds the ethanolic soln of 4 ~ 6 times 50 ~ 60%, is to extract 30 ~ 60min under the condition of 600 ~ 800W in microwave power, and filter, filtrate is concentrated into without alcohol taste;
C. by the concentrated solution of gained in step b organic solvent extraction 2 ~ 3 times, combining extraction liquid, then through anhydrous sodium sulfate drying dehydration, concentrating under reduced pressure, obtain Rhizoma Alpiniae Officinarum volatile oil.
Organic solvent described in step c is the one in ether, sherwood oil.
Beneficial effect of the present invention is: technique is simple, adopt plant tissue Smashing extraction method process raw material, whole process only completes within the several seconds to tens of second, simultaneously owing to eliminating heating, thus effectively can avoid the destruction of volatile oil component, again in conjunction with the high energy effect of microwave, effectively improve the solubility rate of Rhizoma Alpiniae Officinarum volatile oil, its yield be high, superior product quality.
Further illustrate the present invention below in conjunction with embodiment, but the scope of protection of present invention is not limited to following embodiments.
