Abstract
The invention relates to a microwave assisted extracted crofton weed volatile oil which belongs to the technical field of natural plant extraction products. The crofton weed volatile oil is obtained by adopting the following steps of: putting crushed matters of the overground parts of crofton weeds in a glass distilling flask, adding 1-10 times of distilled water in weight for soaking the crushed matters for 0.1-8 hours, placing the distilling flask in a microwave extraction device for continuous extraction for 5-200 minutes, wherein the microwave extraction device has the working frequency of 915MHZ or 2450MHZ and the working power of 50-3000W, extracting distillate for 1-3 times with 10-100mL of diethyl ether or normal hexane, dehydrating by 1-25g of anhydrous sodium sulfate after combining diethyl ether or normal hexane extract liquors, reducing pressure to remove the diethyl ether or normal hexane at 20-70 DEG C, and obtaining the crofton weed volatile oil. The crofton weed volatile oil has the beneficial effects that the crofton weed volatile oil is obtained by using the microwave assisted method, and the yield of the volatile oil is obviously higher than that of the volatile oil obtained by a traditional steam distillation method.
Description
Technical field:
The present invention relates to a kind of Hemp Eupatorium volatile oil that extracts with microwave-assisted, belong to extracted form natural plant product technical field.
Background technology:
Volatile oil claims again essential oil (Essential oils), be present in a class in the plant have aromatic odour, can with wet distillation out and with the general name of the not miscible volatility oily composition of water.Volatile oil is the mixture of the Multiple components such as fatty compounds and aromatics, and is wherein more with the terpenoid or derivatives thereof.
Steam distillation is that volatile oil extracts the most frequently used method, and it has the advantages such as equipment requirements is simple, easy and simple to handle, is widely used in the extraction of plant volatile oil.Temperature is higher, consuming time longer but the weak point of steam distillation is extraction, makes easily in the volatile oil damp and hot chemical ingredients unstable and easy oxidation is decomposed.
Utilizing the method for microwave-assisted to extract plant volatile oil is the new technology that development in recent years is got up, and it has thermal conversion efficiency height, homogeneous heating, need not material is carried out impact, the extraction efficiency high that pre-treatment, the extract such as dry are not subjected to material moisture.Utilize the method extraction plant volatile oil of microwave-assisted to compare with traditional wet distillation extraction method, extraction time can shorten more than 80%, thereby the energy consumption of greatly reducing has improved efficient.Based on above characteristics, the microwave-assisted extraction process is described as " Modern Green extraction process ".
The inventor is through large quantity research, and the result shows: utilize the method for microwave-assisted can effectively extract volatile oil in the Hemp Eupatorium, and the yield of volatile oil is significantly higher than traditional wet distillation extraction method.By literature search, have no the open source literature report identical with the present invention.
Summary of the invention:
The object of the present invention is to provide a kind of Hemp Eupatorium volatile oil that extracts with microwave-assisted.
The Hemp Eupatorium volatile oil that extracts with microwave-assisted of the present invention obtains through following steps:
A. adopt microwave-assisted to extract Hemp Eupatorium volatile oil, the operating frequency of used microwave is 915 megahertzes and 2450 megahertzes, and the microwave operating power is 50～3000 watts;
B. Hemp Eupatorium over-ground part crushed material is placed the glass matrass, add weight and be 1～10 times distilled water immersion 0.1～8 hour, place matrass the microwave extraction instrument to extract 5～200 minutes continuously, distillate is with 10～100 milliliters of ether or n-hexane extraction 1～3 time, restrain anhydrous sodium sulfate dehydration with 1～25 after merging ether or n-hexane extract, 20～70 ℃ of decompressions are waved except ether or normal hexane, namely obtain Hemp Eupatorium volatile oil.
