Technical Field
The invention relates to electronic cigarette liquid and a preparation method thereof, and belongs to the field of electronic cigarettes.
Background
Honeysuckle is a dried flower bud or a flower which is just bloomed of honeysuckle in Caprifoliaceae, and has a long medical history in China. It is sweet and cold in nature, enters lung, heart and stomach channels, has the effects of clearing away heat and toxic materials, and cooling and dispelling wind-heat, and is widely applied to acute febrile diseases and surgical infectious diseases such as upper respiratory tract infection, acute tonsillitis, pharyngitis, furuncle, sore, swelling, mastitis, dysentery, etc. A large number of experimental studies and clinical studies of scholars at home and abroad prove that the honeysuckle has remarkable antiviral efficacy, and is receiving attention in recent years.
The flos Chrysanthemi is dry head-shaped inflorescence of flos Chrysanthemi of Compositae, has cold, sweet and slightly bitter taste, and has effects of suppressing hyperactive liver, improving eyesight, dispelling pathogenic wind, clearing heat, removing toxic substance and relieving swelling. The chrysanthemum contains various medicinal components, mainly comprises volatile oil, brass compounds, amino acid, chlorogenic acid, trace elements and the like, plays an important clinical pharmacological value in a traditional Chinese medicine preparation, mainly has various physiological activities of antibiosis, antivirus, anti-inflammation, anti-tumor, anti-aging and the like, and is clinically used for treating hypertension and coronary heart disease.
Jasmine is perennial evergreen shrub of jasminum of Oleaceae, and is a famous world spice crop. The root, stem, leaf and flower of the Chinese medicinal composition have medicinal value, and are natural Chinese medicaments. The flos Jasmini sambac mainly contains volatile oil, fatty compounds, glycosides, flavonoids, terpenes, lignans, and alkaloids. Has effects in improving immunity, resisting tumor and bacterial virus, resisting inflammation, resisting infection, lowering blood sugar and blood lipid, resisting drug-resistant ulcer, and resisting aging. Meanwhile, the fragrance of the jasmine has the effects of regulating qi and relieving depression, and the fragrance can be used for relieving depression to treat psychological diseases.
The tobacco liquid is a liquid used by an electronic cigarette cartridge, and is generally essence extracted from plants and added with edible spices. Has strong oxidation resistance and does not contain harmful substances such as carbon monoxide, tar and the like. At present, the conventional methods for preparing the electronic cigarette liquid all need to add edible essence, evaporate and concentrate and the like, so that the method has influence on human health or causes reduction of volatile substances and the like, for example: edible essence is added into the electronic cigarette liquid in CN201610276966.7, the edible essence is taken as a food additive, and the excessive intake of the edible essence can cause certain damage to human health, and meanwhile, the extracting solution is concentrated by adopting a reduced pressure rotary evaporation concentration mode, so that the loss of partial volatile substances can be caused in the process; the electronic cigarette liquid in CN201410311997.2 and CN201610518002.9 is added with tobacco extract and tobacco essence, firstly, the tobacco extract also contains nicotine (common name of nicotine), the nicotine can cause addiction or dependence, the repeated use of the nicotine also increases the heart rate and raises the blood pressure and reduces the appetite, secondly, the tobacco essence also belongs to a food additive, and certain harm can be caused to the health of human bodies when the tobacco essence is excessively taken.
Disclosure of Invention
[ problem ] to
At present, the conventional method for preparing the electronic cigarette liquid needs to add edible essence, perform evaporation and concentration operation and the like, so that the method has influence on human health and can reduce volatile substances.
[ solution ]
In order to solve the problems, the invention provides electronic cigarette liquid and a preparation method thereof.
The invention aims to provide an electronic cigarette liquid which comprises the following components in parts by weight:
150 parts of propylene glycol 110-.
In one embodiment of the invention, the electronic cigarette liquid comprises the following components in parts by mass:
150 parts of propylene glycol, 5 parts of honeysuckle, 1 part of chrysanthemum and 1 part of jasmine.
In one embodiment of the invention, the electronic cigarette liquid comprises the following components in parts by mass:
150 parts of propylene glycol, 5 parts of honeysuckle, 1 part of chrysanthemum and 3 parts of jasmine.
In one embodiment of the invention, the electronic cigarette liquid comprises the following components in parts by mass:
150 parts of propylene glycol, 5 parts of honeysuckle, 3 parts of chrysanthemum and 1 part of jasmine.
In one embodiment of the invention, the electronic cigarette liquid comprises the following components in parts by mass:
150 parts of propylene glycol, 5 parts of honeysuckle, 2 parts of chrysanthemum and 2 parts of jasmine.
The second purpose of the invention is to provide a method for preparing the electronic cigarette liquid, which comprises the following steps:
weighing 4-6 parts of honeysuckle, 1-3 parts of chrysanthemum and 1-3 parts of jasmine, then adding 110-150 parts of propylene glycol, and uniformly mixing to ensure that the honeysuckle, the chrysanthemum and the jasmine are completely immersed in the propylene glycol; then carrying out ultrasonic treatment, soaking, heating and filtering to obtain filtrate, namely the electronic cigarette liquid.
In one embodiment of the invention, the mixing is performed by magnetic stirring at 400rpm at 55 ℃ for 2-3h while shaking.
In one embodiment of the present invention, the time of the ultrasound is 30 min.
In one embodiment of the invention, the soaking is 20-30 ℃ (room temperature) standing and soaking for 12 h.
In one embodiment of the invention, the heating is to 75 ℃.
In one embodiment of the invention, the filtration is performed while the solution is still hot, and the filtration is performed twice by using gauze.
The third object of the invention is to provide a method for detecting volatile substances in the cigarette liquid of the electronic cigarette, which comprises the following steps:
extracting dichloromethane and the electronic cigarette smoke liquid according to the ratio of 1: 3; the dichloromethane extract was then concentrated to one tenth of the original volume and then passed through a 0.45 μm organic filter for final testing.
In one embodiment of the present invention, the gas chromatography conditions are:
capillary chromatography column HP-5MS (30 m.times.0.25 mm.times.0.25 μm); the carrier gas is high-purity helium; manual sample introduction is adopted; the temperature of a sample inlet is 260 ℃; the sample volume is 1 mu L; shunting in a shunting mode; the split ratio is 10: 1; the flow rate of the chromatographic column is 1.5 mL/min; the temperature programming is carried out at an initial temperature of 70 ℃, the temperature is kept for 2min, the temperature is increased to 230 ℃ at a speed of 5 ℃/min, and the temperature is kept for 5min (the total operation time is 39 min).

[ advantageous effects ]
(1) Other organic solvents are generally adopted to extract plant components for adding into the electronic cigarette liquid, and the propylene glycol is adopted to directly extract effective components from the plants, so that the propylene glycol is not required to be removed because the propylene glycol is the component of the electronic cigarette liquid. Compared with the conventional method, the method disclosed by the invention omits the process of removing the solvent, and avoids the loss and degradation of volatile components in the process of removing the solvent, so that the electronic cigarette liquid has better quality and lower production energy consumption.
(2) In the detection method, because the propylene glycol has a high melting point and cannot be directly injected, volatile substances in the propylene glycol are extracted by using dichloromethane by utilizing the incompatibility of the dichloromethane and the propylene glycol, and the problem that the extracting solution prepared from the propylene glycol cannot be subjected to gas analysis can be effectively solved.
