Abstract
The invention provides a method for simultaneously extracting gallic acid, ellagic acid and essential oil from eucalyptus camaldulensis. The method is characterized in that eucalyptus camaldulensis leaf powder as a raw material is immersed in a 1-butyl-3-methylimidazolium bromide solution for 2h, the solution is subjected to reflux extraction in a microwave oven device, essential oil is collected by an extractor, 1ml of the extract supernatant is taken, liquid phase detection is detected and gallic acid and ellagic acid content of eucalyptus camaldulensis is calculated. The method has the characteristics of short extraction time, use of an environmentally friendly solvent as an ionic liquid, recycle, cost saving and industrial production convenience.
Description
Technical field
The present invention relates to field of natural product extraction, particularly relate to a kind of ionic liquid microwave-assisted and extract gallic acid in eucalyptus camaldulensis, the method for ellagic acid and eucalyptus camaldulensis essential oil simultaneously.
Background technology
Essential oil belongs to a kind of secondary metabolite, has a lot of biological activity, as antibacterial, antiviral, antimycotic and oxidation-resistance etc.Exactly because so many activity, the research of essential oil is more and more extensive, can play to some extent, can also be used for doing some foodstuff additive in medicine.
Eucalyptus camaldulensis, belongs to Myrtaceae, originates in Australia, now by other country's plantations many, as China, and Spain, Morocco etc.One of reason that eucalyptus camaldulensis is widely cultivated is its adaptive faculty and speed of growth thereof fast.Eucalyptus camaldulensis leaf essential oil is by analysis containing 34 kinds of compositions, main component is 1,8-Cineole, α-Terpineol, α-Terpineol, α-Gurjunene, Aromandendrene, Alloaromadendrene, (+)-Ledene, Globulol, γ-Eudesmol, Cubenol, wherein Aromandendrene and Globulol content is especially high.There is research to confirm, can pulmonary infection be treated by sucking eucalyptus camaldulensis leaf essential oil, there is germ resistance and oxidation-resistance in addition.Ellagic acid and gallic acid also have resistance of oxidation.
Compared with extracting essential oil with hydrodistillation, microwave has and more saves time, and obtains better product, and as compared to the existing technology extracting GA with EA, the solvent toxicity of selection is little, and extraction time is short, and technological process is relatively simple.
Summary of the invention
The object of the present invention is to provide a kind of gallic acid simultaneously extracted in eucalyptus camaldulensis, the method for ellagic acid and eucalyptus camaldulensis essential oil.
To achieve the above object of the invention, the technical solution used in the present invention is as follows:
With red eucalyptus powder for raw material, take red eucalyptus powder in eggplant type flask, the ionic liquid adding 20-60 times of eucalyptus camaldulensis powder quality soaks 2h, put into microwave oven apparatus and carry out refluxing extraction, described ionic liquid is bromination 1-butyl-3 Methylimidazole, described extraction conditions is: ionic liquid concentration is 0.25-2.50mol/l, microwave power 120w-700w, and the microwave time is 5-30min; Collect essential oil simultaneously, the essential oil of collection is carried out GC-MS detection, extracting solution room temperature cools, and gets 1ml supernatant liquor and carries out Liquid Detection, calculate the content of gallic acid, ellagic acid.Advantage of the present invention is: can extract gallic acid, ellagic acid, essential oil simultaneously, save the time greatly compared with hydrodistillation, and ionic liquid is green and environment-friendly solvent, recyclable, saves capital, is convenient to suitability for industrialized production.
