A kind of green Solventless Extraction Process of industrial hemp floral leaf essential oil, this method is to choose the floral leaf of fresh industrial hemp, is put into non-solvent microwave extraction element, and setting microwave power is 100~1000W, Extracting temperature is 100~150 DEG C, extraction time 5~120 minutes；When non-solvent microwave extracts heating, evaporation liquid is collected with condenser pipe, finally obtains cannabis leaf essential oil with oil water separator.Operation is simple for the method for the present invention, green safe environmental protection, does not use any organic solvent, the cannabis leaf essential oil products C BD content of obtained acquisition is high, safe and non-toxic.
Description
Technical field
The present invention relates to a kind of extracting methods of cannabis leaf essential oil, belong to natural product chemistry and plant extract technology neck
Domain.
Background technique
Industrial hemp refers to the hemp that tetrahydrocannabinol content is lower than 0.3%, and industrial hemp is known as Chinese fiber crops by China
It (hemp), is 1 year raw herbaceous plant of Cannabaceae (Cannabinaceae) Cannabis (Cannabis).
Cannabidiol (Cannabidiol, abbreviation CBD) is the main chemical compositions in medicinal plant hemp, is extracted from female
Property hemp plant, be the non-additive ingredient in hemp, have the pharmacological actions such as anti-spasm, antianxiety, anti-inflammatory.It can also be effectively
Eliminate the hallucinogenic action that tetrahydrocannabinol (THC) generates human body, referred to as " anti-drug compound " (anti-marijuana in ground
Compound).Cannabidiol (CBD) can be used for the multiple fields such as drug, health care product, food and chemical product.
Cannabidiol in industrial hemp (CBD) extracting method at present mainly includes organic solvent method, supercritical methanol technology, Asia
Critical method etc..For example, Chinese patent CN106831353A, CN106278828A disclose one kind extracts cannabidiol from hemp
Method and it is a kind of from industrial hemp floral leaf extract cannabidiol method, mainly ethanol extract from water precipitation and column chromatography.China
Patent CN103739585A discloses extraction dihydro cannabinol (CBD) technique from industrial hemp, and solvent uses petroleum ether, just oneself
Alkane or 6# solvent naphtha.Chinese patent CN105535111A discloses a kind of numb medicinal extract of fire rich in cannabidiol and its preparation side
Method is added active carbon, is carried out at decoloration by flame filter press or by activated-charcoal column by subcritical butane abstraction technique
Reason.Chinese patent CN107011125A discloses a kind of method for being enriched with cannabidiol, carries out after carbon dioxide supercritical extraction
Column chromatography.Chinese patent CN206244694U discloses the production equipment of high-purity cannabidiol, comprising: storage tank, equipment for purifying,
Product drying equipment, product storage tank and solvent tank.
The various methods of above-mentioned patent disclosure require special equipment (supercritical methanol technology, subcritical method), and not only technique is multiple
Miscellaneous, extraction cost is high, and using organic solvents such as n-hexanes, cannabidiol (CBD) loss is larger during solvent deposition.
Summary of the invention
The purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of extraction process without using any organic solvent,
The cannabis leaf essential oil products C BD content of obtained acquisition is high, safe and non-toxic, green and healthy, and technological operation is simple and easy
The green Solventless Extraction Process of industrial hemp floral leaf essential oil.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of green Solventless Extraction Process of industrial hemp floral leaf essential oil, comprising the following steps:
A kind of green Solventless Extraction Process of industrial hemp floral leaf essential oil, this method are to choose the flower of fresh industrial hemp
Leaf is put into non-solvent microwave extraction element, and setting microwave power is 100~1000W, and Extracting temperature is 100~150 DEG C, extracts
Time 5~120 minutes；When non-solvent microwave extracts heating, evaporation liquid is collected with condenser pipe, is finally obtained greatly with oil water separator
Fried dough twist leaf essential oil.
The floral leaf of fresh hemp floral leaf selection full-bloom stage of the present invention, water content > 80%.
Microwave extraction method is extracted using microwave radiation as heat source, compared with traditional extraction process, its advantage is that fastly
Speed, energy conservation, saving solvent, pollution is small, extraction efficiency is high, is conducive to extract heat-sensitive substance, can draw to avoid long-time high temperature
The decomposition of the substance risen, particularly suitable for heat-sensitive component or the effective component extracting from natural materials.Solvent-free microwave extraction
It is microwave irradiation to be carried out to raw material, the moisture inside raw material is made by the interior heating of microwave under the conditions of without using organic solvent
It is expanded with gasification, so that body of gland and its oiliness wrappage be made to rupture, the essential oil in cell is released, is existed with the evaporation of moisture
It is condensed outside Microwave emission chamber, is layered in water segregator, that is, collect and obtain, this method is efficient, environmentally friendly, resulting essential oil fragrance
It is high-quality.
The present invention collects evaporation liquid by the floral leaf of fresh process hemp, directly progress Microwave Extraction, then with condenser pipe, finally
Volatile oil is obtained with oil water separator, is had at least the following advantages:
1, simple process can be very good the residual for avoiding organic solvent, environmentally protective, safe nothing without adding any solvent
Poison；
2, extraction time is shorter, can be significantly reduced the degradation of compound and by-product in cannabis leaf essential oil extraction process
Occur, guarantees high product purity, the cannabis leaf essential oil products C BD content of acquisition is high, and recovery rate is up to 80% or more；
3, energy consumption is lower in extraction process, can greatly improve cannabis leaf essential oil production efficiency.
