Description
Technical field
The invention belongs to health product technology fields, relate generally to a kind of side of Jasmine flower drying extraction Jasmine hydrosol
Method.
Background technique
Jasmine, also known as jasmine are the general designation of Oleaceae gelsemium (Jasminum) evergreen shrubs or liana, jasmine
Jasmine the south of the lower reaches of the Yangtze River native to China and west area；India, an Arabic band, center producing region is near the Persian Gulf, now extensively
General plant is planted in subtropical zone.The southeast Heng County Jasmine of Guangxi Zhuang Autonomous Region, yield and quality all rank first in the whole country,
The kind value area and yield of Jasmine account for 80% or so of the whole nation, account for the 60% of world's Jasmine yield, produce fresh jasmine per year
Nearly 100,000 tons, be famous " township of Jasmine ".Jasmine elegant fragrance, faint scent overflow, and can extract jasmine oil, are systems
The raw material of essence is made, Jasmine, leaf, root can be used as medicine, and Jasmine can also smoke tea making leaf, or steam taking juice, japanese rose distillate can be replaced,
It is located in the ground such as Suzhou, Nanjing, Hangzhou, the Jinhua in Jiangnan all to be produced as smoked tea flavour for a long time.Jasmine hydrosol tool
There is apparent relaxation effect, rouses oneself nervous system；It can also gently cough, nurse and improve skin elasticity, desalinate striae of pregnancy and wound
Scar, in terms of the extraction of Jasmine hydrosol, it is main at present using fatty absorption method, extraction or supercritical carbon dioxide fluid extraction into
Row extracts, but these methods are not that there is a problem that separation is difficult, product fragrance is not pure enough there is at high cost,
Thus the price of Jasmine hydrosol is very expensive.
Hydrosol, also known as water hydrosol (Hydrolat) refer to that hydrosol during distillation extraction, is isolated when refining hydrosol
The distillation stoste that the one kind 100% come is saturated, is a kind of byproduct of hydrosol, composition is naturally pure, and fragrance is light pleasant.Hydrosol
It is exactly that virtue treats the resulting condensation aqueous solution of plant distillation.Grease can separate during distillation extraction, because of density difference, hydrosol meeting
It swims in above, moisture is then deposited in the following, these moisture are just hydrosol.In hydrosol other than containing a small amount of hydrosol ingredient,
Also containing the intracorporal water-soluble substances of whole plants.Possess the hydrosol of a hundred percent plant water-soluble substance, contained mineral are supported
Dividing (such as tannic acid and flavonoids) is that hydrosol is lacked.The characteristic of its low concentration is easy to be less readily available for absorption by the skin, complete without essence
And alcoholic ingredient, it does not stimulate mildly, hydrosol is applied to skin surface, is people day for the health for cleaning skin, keeping skin
The essential articles of normal beauty and skin care.
Jasmine hydrosol be from Jasmine extract obtain compared with hydrosol, the property of Jasmine hydrosol as mild as a dove,
Skin will not be stimulated, being not required to dilution just can be used directly, thus use scope is very extensive.It can be used for skin care, such as conductization
Adornment water, modulation facial mask make creams or lotion etc. with cotton pads soak, collocation substrate oil and hydrosol, can also be added in hydrosol
A small amount of hydrosol is to promote curative effect.Jasmine hydrosol can be used as eau de toilette, is also used as summer salubrious moisturizing dew, is sprayed directly on to
On the face, existing light jasmin, moreover it is possible to which skin, noble fragrance and surprising skin effect are nourished in moisturizing whitening, make jasmine
Jasmine hydrosol becomes woman and maintains holy product.
In those early years, there have been the products such as lavender hydrosol and rose in the market, but it is pure to there is no jasmine
Reveal this thing, because refining the tangible too expensive of jasmine hydrosol cost with the way of distillation, rarely producer is refined with the way of distillation
Jasmine hydrosol；And it uses and can not produce by-product when extracting jasmine hydrosol using extraction or supercritical carbon dioxide fluid extraction etc.
Product-Jasmine hydrosol.Have in terms of the research of Jasmine hydrosol it is very much, but but very to the research of Jasmine hydrosol this product
It is few.The document retrieved is entitled " a kind of to extract Jasmine hydrosol and head is fragrant such as application No. is 201510868175.9
The Chinese patent of method ", discloses a kind of method for extracting Jasmine hydrosol and head perfume, and this method includes distillation, condensation, grease
Separation, absorption, a rectifying concentration, alcohol analysis, secondary rectifying concentration and etc.；The energy in the processing step water-oil separating of this method
Isolated Jasmine hydrosol and hydrosol；But this method be with extract Jasmine hydrosol and head perfume based on, be not one with
The process of Jasmine hydrosol as the main purpose is produced, obtained hydrosol amount is few and is only attached to product.Currently, producing
Research in terms of Jasmine hydrosol is not very much, inflammation and red and swollen skin, promotion cell but Jasmine hydrosol energy calmness is releived
Regeneration increases skin elasticity, has effects that desalinate scar etc., and use scope is very extensive, therefore, the life to Jasmine hydrosol
Production method is studied, and it is necessary for developing a kind of production method of Jasmine hydrosol at low cost, high-quality, yield is high
's.
Summary of the invention
Aiming at the shortcomings in the prior art, the purpose of the present invention is to provide a kind of Jasmine flower drying extraction Jasmine is pure
The method of dew.

Then it collects 95% alcohol-water after the elution removal of impurities of 60% alcohol-water through D101 macroporous resin enrichment and elutes position, continue silicon
Plastic column chromatography, through methylene chloride: methanol=20: after 1 elution removal of impurities, collecting methylene chloride: methanol=10: 1 eluted fraction, removal
The Jasmine petal hydrosol extract is obtained after solvent；Using the Jasmine hydrosol extract as raw material, with efficient liquid phase system
Standby chromatography (pHPLC) is isolated and purified.
Step (3), wherein pHPLC condition is as follows: ODS prepares chromatographic column；Eluent using 68%-75% methanol-water in
0-60min gradient elution, in eluent plus the formic acid or trifluoroacetic acid of 0.1-0.5%；Under 254nm or 280nm or 315nm wavelength
Chromatographic peak is collected in detection, is concentrated under reduced pressure after removal solvent up to Jasmine hydrosol ingredient.
In the soaking process in the step (1), the vacuum pump connecting with closed container is opened, is extracted out in closed container
Gas, the jasmine petal in closed container is carried out to vacuumize dipping；Keep container inner pressure constant, 30-60 minutes, together
When, in vacuum-pumping container, form ultrasonic activation；Ultrasonic power is 500W, ultrasonic time 5min；Stopping vacuumizes, extensive
Air pressure in multiple closed container is atmospheric pressure, takes out the jasmine petal by impregnating, spare.
Crushing in the step (1) includes the following steps:
Jasmine petal sealing after immersion is placed in constant temperature 1-2h in -15 to -10 DEG C of refrigerator, then takes out, is placed in
In vacuum freeze drier, -40~-50 DEG C first are refrigerated to the cooling rate of 5-10 DEG C/min, 2-4h is kept, then places again
The cryostat 3h in the freezer that library temperature is -32~-36 DEG C, is crushed to 400 mesh or more in super-micro wall-broken grinder.
Vacuum drying in the step (1) includes the jasmine petal after the immersion that will be obtained, and heat is carried out in drying chamber
Wind-is infrared-microwave drying, 60~80 DEG C of hot blast temperature, and 0.10~0.25W/cm of far infrared radiation intensity2, microwave heating first
Stage power is 200~300W, and second stage power is 300~400W, and phase III power is 200~300W, transmits belt speed
1-2m/min is spent, is recycled 5-8 times.
