Background technology
Lavandula angustifolia (Lavender) is that Labiatae lavandula angustifolia belongs to (Lavandula) plant, is perennial undershrub.The essential oil quality that lavandula angustifolia is refined is splendid, and the graceful fragrance of smell, have the title of " king of spices ", is the important flavor of raw material in the world today.Content containing essential oil in lavandula angustifolia is 3 ~ 5%, and Herba Lysimachiae foenumgraeci quintessence oil can be clearing heat and detoxicating, cleaning skin, controls oil content, freckle removing and whitening, the tender skin of anti-wrinkle, eye haustra-dsipelling black eye, also can promote that damaged tissue regenerates the skin-protecting functions such as recovery.Herba Lysimachiae foenumgraeci quintessence oil has sedation effect to heart, can reduce hypertension, pacify palpitaition, helpful for insomnia, has been widely used in the fields such as medical and health, daily-use chemical industry, food-processing at present.
The extracting method of Herba Lysimachiae foenumgraeci quintessence oil is mainly steam distillation, organic solvent method, there is the problems such as low, the consuming time length of extraction yield, product purity be low in existing water vapour, solvent method not only needs to remove extracting solvent, also can make there is a large amount of residual solvent in product, thus have impact on smell and the purity of Herba Lysimachiae foenumgraeci quintessence oil.In recent years, also have report to use supercritical carbon dioxide process, ultrasonic extraction method Herba Lysimachiae foenumgraeci quintessence oil, but these two kinds of methods to there is equipment cost high, be difficult to realize suitability for industrialized production.
Summary of the invention
The object of the invention is to extract Problems existing for existing Herba Lysimachiae foenumgraeci quintessence oil, a kind of method that can improve Herba Lysimachiae foenumgraeci quintessence oil oil yield is provided.Not only extraction yield is high for the method, product purity is high, also has that cost is low, consume energy low, the advantage such as extraction time is short.
In order to realize above object, the present invention is achieved by the following technical solutions:
Extract a method for Herba Lysimachiae foenumgraeci quintessence oil, comprise the following steps:
(1) mechanical activation: dried in the shade by lavandula angustifolia raw material, adds in agitating ball mill, and under rotating speed is 300-500r/min, mechanical activation 5-10min, obtains lavender powder;
(2) soak: above-mentioned lavender powder is added retort, add cellulase and water again, the weight of described cellulase is lavender powder weight 0.4-0.6%, makes water just steep lavender powder with slabstone pressurization, soak 2-4h at normal temperatures, obtain extracting solution;
(3) distill: pass into water vapour from the bottom of retort and extracting solution is heated, extract 1.5-2h after extracting solution boiling, obtain mixing steam;
(4) condensation: mixing steam obtained above carries out condensation through condenser, obtains oil-water mixture after condensation;
(5) oily water separation: the oil-water mixture that condensation obtains carries out oily water separation through water-and-oil separator, obtains the thick oil of lavandula angustifolia and water;
(6) extract: the thick oil of the lavandula angustifolia obtained extracts through extractor again, after layering, separates upper strata and is Herba Lysimachiae foenumgraeci quintessence oil.
A kind of the above method extracting Herba Lysimachiae foenumgraeci quintessence oil, described agitating ball mill is agitated ball mill.
A kind of the above method extracting Herba Lysimachiae foenumgraeci quintessence oil, the oil yield of described Herba Lysimachiae foenumgraeci quintessence oil is 3.3-3.6%.
A kind of the above method extracting Herba Lysimachiae foenumgraeci quintessence oil, described Herba Lysimachiae foenumgraeci quintessence oil purity reaches more than 95%.
Compared with prior art, the beneficial effect that the present invention obtains is:
(1) the present invention is before distillation extraction Herba Lysimachiae foenumgraeci quintessence oil, by lavandula angustifolia raw material first through mechanical activation process, lavandula angustifolia is destroyed the cell walls of plant by mechanical activation under the mechanical force such as friction, collision, impact, shearing, and make grain refine, make the essential oil of lavandula angustifolia be more prone to extract, thus improve oil yield.
(2) the present invention is before distillation extraction Herba Lysimachiae foenumgraeci quintessence oil, first use cellulase and water soaking lavandula angustifolia raw material, the cellulose skeleton of composition cell walls can be degraded into glucose by cellulase step by step, and then destroy cell wall skeleton structure, Herba Lysimachiae foenumgraeci quintessence oil is more easily extracted, not only increase oil yield, also shorten the distillation extraction time.
(3) oil yield of Herba Lysimachiae foenumgraeci quintessence oil of the present invention is 3.3-3.6%, and traditional method oil yield is only 2.0-2.5%.
(4) the thick oil of lavandula angustifolia after oily water separation of the present invention, first through extracting and separating, improves the purity of product, and the Herba Lysimachiae foenumgraeci quintessence oil purity obtained reaches more than 95%, and existing extracting method purity generally only reaches 90%.
(5) the inventive method also have simple to operate, extraction time is short, low cost and other advantages, is applicable to suitability for industrialized production.
