Abstract
This invention discloses a kind of abstracting method of aspic volatile oil, including the following steps: 1. the materials of the aspic is minced or stirred to pieces in 5-40 mesh, put it into extracting cauldron, the temperature of cauldron rises to 30-55 Deg. C; 2. to extracting cauldron input the critical CO2 of state pressurize 20-40MPa; The velocity of flow with 10-25 kg/h circulates the raw materials of aspic, the pressure of separating cauldron is 5- l0MPa, temperature is 40-60 Deg. C, extraction for 1.0-4.0h, discharge the extract from the bottom of the separation cauldron, standby then obtain the essence after the oil-water separation. Advantages: simple operation and high efficiency.
Description
Technical field
The present invention relates to the method for a kind of production (squeezing, extraction) or refined natural essence oil from plant, in particular, the present invention relates to a kind of method of from the natural phant lavandula angustifolia, extracting Herba Lysimachiae foenumgraeci quintessence oil.
Background technology
Lavandula angustifolia is a kind of natural perfume plant of preciousness, originates in the Mediterranean Sea bank, and China introduces a fine variety lavandula angustifolia from 1960 front and back on Xinjiang and other places and succeeds.The plants essential oil that extracts from lavender flower, stem, leaf contains multiple natural perfume composition, is widely used in industries such as daily necessities, makeup, medicine.Unique fragrance that Herba Lysimachiae foenumgraeci quintessence oil and goods thereof give out has expelling parasite, eliminates the unusual smell, purifies air, and regulates physiological function, stimulates circulation, and produces refreshing effect to the mind, alleviates multiple efficacies such as stress.At present, hydrodistillation or solvent-extraction process are adopted in the extraction of Herba Lysimachiae foenumgraeci quintessence oil usually.The former because temperature is higher, makes easily that heat-sensitive materials in the essential oil is damaged, the volatilization of lower boiling aroma component in the hydrodistillation operating process, and influences the quality of product.The latter uses organic solvent extraction, except Harmful chemicals that organic solvent contained can remain in the product, also needs to reclaim solvent with distillation method at the final step of producing and just can obtain product, and process energy consumption is big, process is complicated, have unsafe factor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method of new extraction Herba Lysimachiae foenumgraeci quintessence oil, and this method safety, efficient has overcome the disadvantages associated of hydrodistillation and solvent-extraction process, has a good application prospect.
The technical solution used in the present invention: a kind of extracting method of Herba Lysimachiae foenumgraeci quintessence oil comprises the following steps:
A. with raw material lavandula angustifolia chopping or blend the order to 5-40, insert extraction kettle, the temperature of extraction kettle rises to 30-55 ℃.In extraction kettle, feed the CO of supercritical state
2, pressure is 20-40MPa; Flow velocity is 10-25kg/h.
B. use supercritical CO
2Cycling extraction raw material lavandula angustifolia, the pressure of separating still are 5-10MPa, and temperature is 40-60 ℃, emit extract from the separating still bottom behind the extraction 1.0-4.0h, leave standstill after oil/water sepn obtains Herba Lysimachiae foenumgraeci quintessence oil.
Step a is with the chopping of raw material lavandula angustifolia or blend the order to 5-40, inserts extraction kettle to wherein adding to carry again after 1-25h is placed in agent.
Described raw material lavandula angustifolia is lavandula angustifolia fresh flower or lavandula angustifolia dried flower or lavandula angustifolia stem, leaf.
Describedly carry agent and be selected from alcohol-water.
The described massfraction that carries the agent alcohol-water is 55-85%.
The described consumption that carries agent is 0.8-1.2 a times of raw material lavandula angustifolia consumption.
Beneficial effect of the present invention: supercritical CO
2Fluid density is big, viscosity is liquid 1%, spread coefficient is liquid 100 times, have the short time of balancing each other and very fast dissolution rate, can fast the plants essential oil in the raw material lavandula angustifolia extracted near under the normal temperature condition.The present invention has used this supercritical liquid extraction technique to have extracted volatile oil in the natural lavandula angustifolia from lavandula angustifolia or lavender flower, stem, leaf.The present invention has overcome the operation of traditional water distillation method because temperature is higher, cause that heat-sensitive materials in the essential oil is damaged, the volatilization of lower boiling aroma component, influence the insufficient shortcoming of the quality of product, also overcome the shortcoming that contains dissolvent residual in the product that the conventional solvent extraction method causes, kept the biological activity of natural aromatic composition and its composition in the lavandula angustifolia.The present invention is easy and simple to handle, efficient is high.The volatile oil that the present invention extracts from lavandula angustifolia and lavender flower can be used for preparing daily necessities, makeup, medicine etc., has purposes widely.For example perfumed soap, lavender liquid, toilet water, menthocamphorate, toilet powder shui, toothpaste, cigarette etc.
Embodiment
By embodiment the present invention is described in further detail, a kind of extracting method of Herba Lysimachiae foenumgraeci quintessence oil comprises the following steps: that a. with raw material lavandula angustifolia chopping or blend the order to 5-40, inserts extraction kettle, the temperature of extraction kettle rises to 30-55 ℃, feeds the CO of supercritical state in extraction kettle
2, pressure is 20-40MPa; B. use supercritical CO
2Cycling extraction raw material lavandula angustifolia, the pressure of separating still are 5-10MPa, and temperature is 40-60 ℃, emit extract from the separating still bottom behind the extraction 1.0-4.0h, leave standstill after oil/water sepn obtains Herba Lysimachiae foenumgraeci quintessence oil.At step a the raw material lavandula angustifolia is shredded or blends to the 5-40 order, can insert extraction kettle again, better effects if after 1-24h is placed in agent to wherein adding to carry.Carry agent and be selected from alcohol-water, massfraction is 55-85%, and consumption is 0.8-1.2 a times of raw material lavandula angustifolia consumption.Described raw material lavandula angustifolia is selected from lavandula angustifolia fresh flower or lavandula angustifolia dried flower or lavandula angustifolia stem, leaf.
