Abstract
The invention particularly relates to an extraction method of jasmine essential oil, belonging to the technical field of extraction of essential oil from flowers. The extraction method comprises the following steps of performing impurity removal, drying, and smashing on dry jasmine; adding 90 percent (volume) ethyl alcohol of which the weight is four times of the jasmine, standing for 12 hours at 22 DEG C, filtering, and obtaining an ethyl alcohol solution; performing evaporation and concentration on the obtained ethyl alcohol solution until the quarter of the obtained ethyl alcohol solution is left, adding petroleum ether of which the weight is two times of a concentrated solution, extracting for three times, collecting the lower layer of heavy liquid, and recycling the petroleum ether layer of the upper layer of light liquid; putting the heavy liquid obtained through extraction into a molecular distillation tank for vacuum distillation, purification and condensation, and obtaining the jasmine essential oil; the pressure in the molecular distillation tank is controlled to be 0.05MPa, the compressed air pressure is not greater than 0.5MPa; the vacuum degree in the molecular distillation tank is 55MPa. Compared with the prior art, the extraction method has the beneficial effects that the operation is simple, the quality of the prepared jasmine essential oil is good, and the oil extraction rate can reach 0.08 percent.
Description
Technical field
The present invention relates to from the technical field spending middle extraction quintessence oil, particularly to a kind of Extraction method for jasmine flower essential oil.
Background technology
Flowers are the important component parts of China's Chinese herbal medicine, and Flos Lonicerae, Flos Chrysanthemi, Chimonanthus praecox (L.) Link., Hibisci Mutabilis, Cuculus polioephalus, Chinese rose, Flos Nelumbinis etc. are common Chinese crude drug.Jasmine leaf color jade green, flower pure white smooth as jade, fragrance is clear and sweet soft refined, is described as first of many fragrant flowers by people, having fabulous Flos Jasmini Sambac is the important source material extracting essence.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of Extraction method for jasmine flower essential oil.
For achieving the above object, the technical solution used in the present invention is:
A kind of Extraction method for jasmine flower essential oil of the present invention, comprises the steps:
A, by dry Flos Jasmini Sambac remove impurity, be dried, be crushed to 10 mesh, standby；
B, addition weight are the 90%(volume of Flos Jasmini Sambac weight 4 times) ethanol, at 22 DEG C, stand 12h, filter, obtain alcohol liquid；
C, by 1/4th of gained alcohol liquid evaporation and concentration to former gained alcohol liquid measure weight, be subsequently adding the petroleum ether extraction 3 times that weight is gained concentrated solution 2 times, collect lower floor's heavy-fluid, upper strata light liquid petroleum ether layer reclaims；
D, the heavy-fluid being obtained by extraction are sent into molecular distillation tank and are carried out vacuum distilling purification condensation, obtain Flos Jasmini Sambac quintessence oil；Distillation pressure inside the tank controls at 0.05MPa, and compressed air pressure is less than 0.5MPa；Vacuum in tank: 55MPa.
The present invention compared with prior art provides the benefit that: this method is simple to operate, and the Flos Jasmini Sambac quintessence oil quality of preparation is good, and oil yield is up to 0.08%.
Detailed description of the invention
Describing the present invention below in conjunction with specific embodiment, following embodiment and explanation are only used for explaining the present invention, but not as a limitation of the invention.
A kind of Extraction method for jasmine flower essential oil of the present invention, comprises the steps:
