Abstract
The invention relates to a method for extracting alpinia oxyphylla volatile oil, in particular relates to a method for extracting alpinia oxyphylla volatile oil by adopting ultrasonic and microwave, and belongs to the technical field of natural plant extraction products. The method comprises the treatment steps of pulverizing dry alpinia oxyphylla fruits, putting into a glass vessel, adding distilled water in an amount which is 3-8 times weight of the alpinia oxyphylla, continuously extracting for 1-4 hours with ultrasonic and microwave by controlling the ultrasonic at 600W (normally open) and controlling the microwave power at 500-1,000W, filtering, extracting the filtrate with an organic solvent for 1-3 times, combining the extracts, drying with anhydrous sodium sulfate, and concentrating under reduced pressure, thus obtaining the alpinia oxyphylla volatile oil. The alpinia oxyphylla volatile oil is extracted through ultrasonic and microwave synergy by adopting a modern extraction technology, so that the method is simple, short in extraction time and high in selectivity, the yield of the volatile oil is significantly higher than that of the traditional extraction method, and the method is suitable for industrialized production.
Description
Technical field
The present invention relates to a kind of extracting method of Fructus Alpinae Oxyphyllae volatile oil, be specifically related to a kind of collaborative method of extracting Fructus Alpinae Oxyphyllae volatile oil of ultrasonic-microwave that adopts, belong to extracted form natural plant product technical field.
Background technology
Intelligence development, the dry fruit of genus zingiberaceous plant intelligence development, another name Sharpleaf Galangal Fruit, intelligence development, be one of Hainan Si great Nan medicine.Theory of traditional Chinese medical science thinks, it has the effect of " warm spleen, warm kidney, solid and gas, puckery essence ".Modern pharmacological research shows, the effect such as that intelligence development has is anticancer, cardiac stimulant, antibacterial, anti-inflammatory, analgesia.Intelligence development contains number of chemical composition, and its main component is volatile oil, and in oil, main component has eucalyptol, zingiberene, zingiberol etc.
Steam distillation is that volatile oil extracts the most frequently used method, and it possesses, and equipment requirements is simple, simple operation and other advantages, in the extraction of plant volatile oil, is widely used.But the weak point of steam distillation is extraction, temperature is higher, consuming time longer, easily makes in volatile oil, damp and hot unstable and oxidizable chemical composition to be decomposed.
Ultrasonic-microwave method is as a novel extractive technique, mainly utilize the high energy effect of hyperacoustic cavitation effect and microwave, strengthen the mass-transfer efficiency of extract solutes, impelled solvent to penetrate in plant tissue, thereby reached the effect of extracting efficiently, fast plant volatile oil.The inventor is through a large amount of research, and result shows: utilize the method for ultrasonic-microwave synergistic extraction can effectively extract Fructus Alpinae Oxyphyllae volatile oil, and the yield of volatile oil is significantly higher than traditional wet distillation extraction method.By literature search, have no identical with the present invention open source literature report.
Summary of the invention
The object of the present invention is to provide a kind of method that technique is simple, energy-conservation, volatile oil is extracted in timesaving from intelligence development.
The present invention includes following steps:
Intelligence development dry fruit is pulverized, be placed in Glass Containers, add the distilled water of 3 ~ 8 times of weight, adopt ultrasonic-microwave to extract, control ultrasonic wave 600W, microwave power 500 ~ 1000W extracts 1 ~ 4h continuously, filters, and filtrate is used to organic solvent extraction 1 ~ 3 time, combining extraction liquid, anhydrous sodium sulfate drying, concentrating under reduced pressure, obtains Fructus Alpinae Oxyphyllae volatile oil.
Organic solvent of the present invention is ether, normal hexane or hexanaphthene.
Beneficial effect of the present invention is: (1) has that efficiency is high, homogeneous heating, without the impact, the extraction yield advantages of higher that the pre-treatment such as material is dried, extract are not subject to material water ratio; (2) Fructus Alpinae Oxyphyllae volatile oil yield is apparently higher than the Fructus Alpinae Oxyphyllae volatile oil yield of traditional extraction by steam distillation.
Below in conjunction with embodiment, further illustrate the present invention, but the scope of protection of present invention is not limited to following embodiment.
