Abstract
The invention relates to a flos magnoliae volatile oil extraction method, and in particular relates to a flos magnoliae volatile oil continuous countercurrent ultrasonic extraction method. The process comprises the following steps: choosing non-mildewing and impurity-free dry flos magnolia, crushing, sieving with a 60 mesh sieve, adding 3 ~ 8 times by weight of distilled water for 1 to 3H of 20 ~ 40KHz continuous countercurrent ultrasonic extraction at 50 to 80 DEG C to obtain a leach liquor by the solid-liquid separation, using an organic solvent for extraction for 2 ~ 3 times, merging the extracted liquid, drying with anhydrous sodium sulfate, and concentrating under vacuum to obtain flos magnoliae volatile oil. The method uses a modern extraction technology for continuous countercurrent ultrasonic extraction of the flos magnoliae volatile oil to avoid damages of heat sensitive components and chemical unstable components in essential oil due to two high temperature of a traditional extraction method, and the method is simple in process, short in extraction time, high in yield, and suitable for industrial production.
Description
Technical field
The present invention relates to a kind of extracting method of Flos Magnoliae volatile oil, be specifically related to a kind of method that adopts continuous flow upstream supersound extraction Flos Magnoliae volatile oil, belong to vegetable oil extraction technical field.
Background technology
Flos Magnoliae is the dry flower of Magnoliacea plant Flos Magnoliae, Magnolia denudata or Flos Magnoliae, another name Flos Jasmini Nudiflori, flos magnoliae.Property and flavor of peppery and warm, returns lung meridian.The effect with dispersing wind and cold, logical Bi Qiao, is used for the treatment of the diseases such as headche due to wind-cold, nasal obstruction, nasal sinusitis, turbid nasal discharge.The main active of Flos Magnoliae is volatile oil, comprise 1,8-eucalyptol, eugenol, methyl chavicol etc., there are obvious contraction nasal mucosa vessels and antihistaminic effect, and can increase blood flow rate, improve microcirculation and good antiallergic and antiasthmatic effect, can be used as the component of the acute and chronic sinusitis for the treatment of and allergic rhinitis medicine.
At present, extracting the main method of Flos Magnoliae volatile oil has: steam distillation, solvent extraction method, supercritical ultrasonics technology, supercritical fluid extraction etc., all Shortcomings.Steam distillation is that volatile oil extracts the most frequently used method, and the equipment and manipulation of this method is fairly simple, and small investment is widely used in the extraction of plant volatile oil.But the weak point of steam distillation is extraction, temperature is higher, consuming time longer, easily makes in volatile oil, thermally labile and oxidizable chemical composition to be decomposed; In ultrasonic extraction leaching process, ultrasonic attenuation is serious, causes ultrasonic inhomogeneously, causes that extraction ratio is low can not work continuously, and treating capacity is little; And although supercritical fluid method yield is high, apparatus expensive, maintenance difficult, is not suitable for suitability for industrialized production.
In order to overcome above shortcoming, the present invention adopts continuous flow upstream supersound extraction, has realized continuous operations, has improved production efficiency, and yield is high.By literature search, have no about adopting continuous flow upstream ultrasonic extraction to extract the report of Flos Magnoliae volatile oil.
Summary of the invention
The object of the present invention is to provide that a kind of technique is simple, time-saving and efficiency and the higher method of extracting volatile oil from Flos Magnoliae of yield.
The present invention includes following steps:
Select do not go mouldy, pure dry Flos Magnoliae, pulverize, cross 60 mesh sieves, the distilled water that adds 3 ~ 8 times of weight, under 50 ~ 80 ℃, 20 ~ 40KHz, after continuous flow upstream supersound extraction 1 ~ 3h, solid-liquid separation obtains extracting solution, and extracting solution is through organic solvent extraction 2 ~ 3 times, combining extraction liquid, anhydrous sodium sulfate drying, concentrating under reduced pressure, obtains Flos Magnoliae volatile oil.
Organic solvent of the present invention is a kind of in petroleum ether, normal hexane or cyclohexane extraction.
The invention has the advantages that: (1) does not need the steps such as immersion, and equipment is simple, with traditional method, compare also time-saving and efficiency more; (2) reaction condition is gentle, avoided due to excess Temperature, extraction time long thermal sensitivity composition or the chemically unstable composition of making decompose.
Below in conjunction with the specific embodiment, further illustrate the present invention, but the scope of protection of present invention is not limited to following embodiment.
the specific embodiment:
Embodiment 1:
Select do not go mouldy, pure dry Flos Magnoliae, pulverize, cross 60 mesh sieves, get 500g powder, the distilled water that adds 8 times of weight, under 50 ℃, 20KHz, after continuous flow upstream supersound extraction 3h, solid-liquid separation obtains extracting solution, and extracting solution is through petroleum ether extraction 3 times, combining extraction liquid, anhydrous sodium sulfate drying, concentrating under reduced pressure, obtains flaxen Flos Magnoliae volatile oil, have peat-reek, yield is 3.5%.
Embodiment 2:
Select do not go mouldy, pure dry Flos Magnoliae, pulverize, cross 60 mesh sieves, get 500g powder, the distilled water that adds 6 times of weight, under 70 ℃, 40KHz, after continuous flow upstream supersound extraction 2h, solid-liquid separation obtains extracting solution, and extracting solution is through n-hexane extraction 3 times, combining extraction liquid, anhydrous sodium sulfate drying, concentrating under reduced pressure, obtains flaxen Flos Magnoliae volatile oil, have peat-reek, yield is 4.2%.
Embodiment 3:
Select do not go mouldy, pure dry Flos Magnoliae, pulverize, cross 60 mesh sieves, get 500g powder, the distilled water that adds 4 times of weight, under 80 ℃, 40KHz, after continuous flow upstream supersound extraction 1h, solid-liquid separation obtains extracting solution, and extracting solution is through cyclohexane extraction extraction 2 times, combining extraction liquid, anhydrous sodium sulfate drying, concentrating under reduced pressure, obtains filemot Flos Magnoliae volatile oil, have peat-reek, yield is 3.8%.
Claims (2)
1. the extracting method of a Flos Magnoliae volatile oil, it is characterized in that, comprise the following steps: select do not go mouldy, pure dry Flos Magnoliae, pulverize, cross 60 mesh sieves, the distilled water that adds 3 ~ 8 times of weight, under 50 ~ 80 ℃, 20 ~ 40KHz, after continuous flow upstream supersound extraction 1 ~ 3h, solid-liquid separation obtains extracting solution, and extracting solution is through organic solvent extraction 2 ~ 3 times, combining extraction liquid, anhydrous sodium sulfate drying, concentrating under reduced pressure, obtains Flos Magnoliae volatile oil.
