Abstract
The invention provides a method for extracting effective components from fresh mint leaves. The method comprises a vapor distillation method and a supercritical CO2 extraction method. The method has the beneficial effects that the vapor distillation method has the advantages of simple equipment and no need of special reagent; for the supercritical CO2 extraction method, the yield is relatively high, CO2 is easy to obtain and cost is low.
Description
Technical field
The invention belongs to Chinese materia medica field, especially relate to the method for effective component extracting in a kind of new fresh mint leaf.
Background technology
New fresh mint leaf has clearing away summer-heat and eliminating dampness, rise and send out sliding sun, effect that Herb contains volatile oil, can stomach invigorating dispels the wind, eliminates the phlegm, function of gallbladder promoting, spasmolytic, improve sense Mao fever, throat, swell and ache, and eliminate the symptoms such as headache, skin itching, abdominal part flatulence, diarrhoea, dyspepsia.The main component of new fresh mint leaf is menthol, menthone, glycoside and multiple free amino acid, but the harvesting of fresh Herba Menthae and storage are limited by when and where all, people through concocting, form dry mentha leave new fresh mint leaf, can make the alcohols of part and trace element disappear.
In Herba Menthae, main component is volatile oil, what the extraction of volatile oil was commonly used has steam distillation, cold-maceration, supercritical ultrasonics technology, supercritical CO 2 method, the content of Oleum menthae in fresh Herba Menthae is the highest, and above method is improved to be applicable to extract quintessence oil from fresh Herba Menthae.
Summary of the invention
The object of this invention is to provide a kind of from new fresh mint leaf the method for effective component extracting.
Technical scheme of the present invention is: the method for effective component extracting from new fresh mint leaf, comprises steam distillation and supercritical CO
2extraction.
The extracting method of Herba Menthae effective ingredient is:
Extraction by steam distillation Herba Menthae effective ingredient: get new fresh mint leaf and clean, dry, weigh, pulverize; Put in volatile oil extractor, add water, extract 5-8 hour, collect extract, with anhydrous sodium sulfate dehydration, filter paper filtering.
Supercritical CO
2extraction extracts Herba Menthae effective ingredient: get new fresh mint leaf and clean, dry, weigh, smash; Pack extraction kettle into.Be 8-10 MPa in extracting pressure, extraction temperature is 30-48 DEG C, CO
2flow is under the condition of 20-28 L/h, and extraction 80-100 minute, collects extract, with the de-CO of anhydrous sodium sulfate
2, filter paper filtering.
The advantage of steam distillation is that equipment does not simply need special reagent, supercritical CO
2the yield of extraction is higher, and CO
2easily obtain, cost is low.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described, but do not limit the present invention.
embodiment 1
A method for effective component extracting from new fresh mint leaf, extraction by steam distillation Herba Menthae effective ingredient:
Get new fresh mint leaf 10kg, clean, dry, weigh, pulverize; Put in volatile oil extractor, the 20L that adds water, extracts 6 h, collects extract, with anhydrous sodium sulfate dehydration, and filter paper filtering.Obtain extract 580g, yield is 5.8%.
embodiment 2
A method for effective component extracting from new fresh mint leaf, supercritical CO
2extraction extracts Herba Menthae effective ingredient:
Get new fresh mint leaf 10kg and clean, dry, weigh, smash; Pack extraction kettle into.Be 9MPa in extracting pressure, extraction temperature is 45 DEG C, CO
2flow is under the condition of 25 L/h, extracts 100 minutes, collects extract, with the de-CO of anhydrous sodium sulfate
2, filter paper filtering, obtains extract 690g, and yield is 6.9%.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the present patent application scope, within all should still belonging to patent covering scope of the present invention.
