When extracted again by evaporation, be centrifugally separating to obtain cape jasmine flower essential oil.
Specific step is as follows for the method:
1) collection of gardenia waste liquid
Taking fresh cape jasmine flower is raw material, after extracting cape jasmine essential oil with steam distillation, collects gardenia waste liquid；
2) concentration of gardenia waste liquid
Gardenia waste liquid is concentrated under reduced pressure under the conditions of 50-75 DEG C, the 1/10-1/5 of original volume is concentrated into, obtains gardenia
Waste liquid concentrate；
3) hydrolysis of gardenia waste liquid
The concentrated sulfuric acid for taking the gardenia waste liquid volume of the concentrated liquid 8 ~ 10% is slowly added into gardenia waste liquid concentrate, and constantly stirs
Mix, heating evaporation extracts at being 100-110 DEG C in temperature, and the hydrolysis of 3 ~ 5 h(of extraction time carries out simultaneously at the extraction), collect Cape jasmine
Son flower pulp thickening object, stands cooling；
4) separation of cape jasmine essential oil
Gardenia pulp thickening object after cooling is placed in whizzer and is centrifuged, cape jasmine flower essential oil is obtained.
The collection method of gardenia waste liquid described in step 1) is as follows: taking fresh cape jasmine flower, 1-3 times of weight is added
Water, using extraction by steam distillation, 90-100 DEG C of Extracting temperature, 1 ~ 3 h of extraction time pulls colored slag out after extraction, will
6 ~ 8 h of gardenia waste liquid cooling and standings collects filtrate, i.e. gardenia waste liquid through 200 ~ 300 mesh net filtrations.
The mass concentration of the concentrated sulfuric acid described in step 3) is 98%.
Centrifugal speed described in step 4) is 4000-6500rpm, centrifugation time 5-10min.
There are the glycoside precursor compounds of linalool in cape jasmine fresh flower extract.Linalool has analgesia, antianxiety, town
A variety of pharmacological activity such as quiet hypnosis, anti-inflammatory, antitumor, antibacterial, prospect in medicine are very wide.Gardenia after extracting cape jasmine essential oil
Linalool glycoside precursor substance in waste liquid, if the cape jasmine flower essential oil for obtaining and being rich in linalool can be extracted by hydrolysis,
It not only utilizes waste again, reduces disposal of pollutants, the yield of cape jasmine flower essential oil can also be improved, improve economic effect
Benefit.
Therefore, the invention adopts the above technical scheme, to extract the gardenia waste liquid after cape jasmine essential oil as raw material, passes through acid
The glycoside precursor substance in gardenia waste liquid is hydrolyzed, the volatilization after hydrolyzing while hydrolysis by extraction by steam distillation
Property ingredient, extract the cape jasmine flower essential oil obtained rich in linalool, can be used for field of medicaments, and for purifying, extract linalool
Monomer.
The method of the present invention is easy, low in cost, easily operated, and by developing and using gardenia waste liquid, cape jasmine can be improved
The yield of flower essential oil, increases economic efficiency.
