Abstract
The invention relates to an extraction method of a semen brassicae volatile oil. The extraction method comprises the following processing steps: drying and crushing semen brassicae, sieving by use of a 40-mesh sieve, adding 3-5 times of acetic acid/sodium acetate buffer solution, wherein the amount of the acetic acid/sodium acetate buffer solution is 3-5 times that of the semen brassicae, and the pH value of the acetic acid/sodium acetate buffer solution is 4-6, mixing evenly, adding ascorbic acid, and continuously hydrolyzing for 90-120 minutes at a temperature of 40-60 DEG C under the conditions of an ultrasonic frequency of 40KHz and the power of 400-60W; and after finishing hydrolyzing, extracting a volatile oil by use of a water vapor distillation method to obtain the faint yellow semen brassicae volatile oil. The extraction method of the semen brassicae volatile oil is simple in process and low in energy consumption, and the yield of the volatile oil is remarkably higher than that of a traditional extraction method.
Description
Technical field
The present invention relates to a kind of extracting method of White Mustard Seed volatile oil, belong to extracted form natural plant product technical field.
Background technology
White Mustard Seed is the dry mature seed of cress sinapsis alba.Warm in nature, taste is pungent; There is the open-minded phlegm profit of warm lung gas, resolving mass and removing the obstruction of the collateral pain relieving; Be mainly used in that cold asthma due to excessive phlegm is coughed, distending pain in the chest and hypochondrium, the stagnant channels and collaterals of phlegm, joint numbness, pain, phlegm-damp oozing in the body, cloudy subcutaneous ulcer pyogenic infections etc.White Mustard Seed volatile oil is colourless or flaxen oily matter, and easily volatilization, has sharp flavor.White Mustard Seed volatile oil is rich in isothiocyanic acid salt material, and this class material has certain bacteriostatic activity, and research shows, takes in isothiocyanic acid salt and also have effect of preventing cancer in meals, and among the anti-tumor activity of this type of material further excavated.
White Mustard Seed volatile oil is hydrolyzed sinigrin by myrosin and produces, and the vigor of myrosin is subject to being permitted multifactorial impact, mainly contains pH, temperature and ascorbic acid concentrations etc.Research shows, it is maximum that the vigor of myrosin can reach between pH3.4 ~ 5.7, and between 5.0 ~ 8.0, still have quite high vigor; And temperature is had nothing in common with each other on the impact of myrosin activity in different plants, the maximum value of vigor is substantially between 30 ~ 70 DEG C; Lower concentration xitix can activate myrosin activity, the concentration that the xitix of high density again can inhibitory enzyme.
Ultrasonic wave refers to that frequency is higher than 20Hz, the sound wave beyond people's threshold of audibility.The mechanism of supersound extraction comprises mechanical schemes and cavitation mechanism and calorifics mechanism.Due to effects such as cavitation, mechanical disintegration, stirring and the calorifics of ultrasonic vibration, in earthquake process, the tangential force that cavitation bubble miniflow around produces solution Chinese medicinal materials to the infiltration in cell, is accelerated the hydrolysis of sinigrin with accelerated solvent.
Summary of the invention
The object of the present invention is to provide the method for the extraction White Mustard Seed volatile oil that a kind of technique is simple, extraction yield is high, product quality is good.
The present invention includes following steps:
By White Mustard Seed drying and crushing, cross 40 mesh sieves, add acetic acid/sodium acetate buffer solution of pH4 ~ 6 of 3 ~ 5 times, mix, add xitix, be 40KHz in ultrasonic frequency, under the condition that power is 400 ~ 600W, in 40 ~ 60 DEG C of continuous hydrolysis 90 ~ 120min; After hydrolysis finishes, adopt extraction by steam distillation volatile oil, obtain flaxen White Mustard Seed volatile oil.
The concentration of xitix of the present invention is 0.3 ~ 0.6mol/L.
Beneficial effect of the present invention is: due to effects such as cavitation, mechanical disintegration, stirring and the calorifics of ultrasonic vibration, in earthquake process, the tangential force that cavitation bubble miniflow around produces solution Chinese medicinal materials to the infiltration in cell, is accelerated the hydrolysis of sinigrin with accelerated solvent.
Further illustrate the present invention below in conjunction with embodiment, but the scope of protection of present invention is not limited to following embodiment.
embodiment:
Embodiment 1:
By White Mustard Seed drying and crushing, cross 40 mesh sieves, add acetic acid/sodium acetate buffer solution of the pH4 of 3 times, mix, adding concentration is the xitix of 0.3mol/L, is 40KHz in ultrasonic frequency, under the condition that power is 400, in 60 DEG C of continuous hydrolysis 90min; After hydrolysis finishes, adopt extraction by steam distillation volatile oil, obtain the White Mustard Seed volatile oil of faint yellow transparence, yield is 0.85%.
Embodiment 2:
By White Mustard Seed drying and crushing, cross 40 mesh sieves, add acetic acid/sodium acetate buffer solution of the pH5 of 5 times, mix, add xitix, be 40KHz in ultrasonic frequency, under the condition that power is 500W, in 50 DEG C of continuous hydrolysis 120min; After hydrolysis finishes, adopt extraction by steam distillation volatile oil, obtain the White Mustard Seed volatile oil of faint yellow transparence, yield is 1.13%.
Embodiment 3:
By White Mustard Seed drying and crushing, cross 40 mesh sieves, add acetic acid/sodium acetate buffer solution of the pH6 of 4 times, mix, add xitix, be 40KHz in ultrasonic frequency, under the condition that power is 600W, in 40 DEG C of continuous hydrolysis 100min; After hydrolysis finishes, adopt extraction by steam distillation volatile oil, obtain the White Mustard Seed volatile oil of faint yellow bright shape, yield is 1.11%.
