Analysis detection 1：Sensory quality assessment
The tobacco extract of Example 1~4 and comparative example 1, respectively equivalent be applied on the cigarette paper of blank cigarette, apply
The amount of smearing accounts for 2/10000ths of cigarette weight, and gained cigarette sample number consecutively is A~E.According to standard YC/T498-2014《Reconstruction
Tobacco leaf (paper process) sensory evaluation method》Sample evaluation rule, aesthetic quality is carried out to cigarette A~E and is smoked panel test, as a result such as table 1
It is shown.
1 cigarette sample aesthetic quality's grade form of table
As shown in Table 1, the sense organ marking of cigarette E is 68.0 points, and the sense organ marking of cigarette A~D is 69.0~72.0 points.Tool
Body, cigarette A~D is promoted in terms of perfume quantity and harmony, and cigarette A~C decreases in terms of irritation, cigarette A
~B decreases wherein in terms of aroma quality and withered and burnt smell, the marking highest of cigarette A, in aroma quality, perfume quantity and harmony
It rises obviously, irritation and withered and burnt smell reduce significantly.Described above, the tobacco extract of Examples 1 to 4 is used for cigarette, Neng Gouyou
Effect promotes aroma quality, perfume quantity and/or the harmony of cigarette, reduces the irritation and/or withered and burnt smell of cigarette, improves cigarette sense organ
Quality.
Analysis detection 2：Gaschromatographic mass spectrometry detects
It is respectively caused in gas chromatography mass spectrometry (GC/MS) further detection 1 two groups of tobacco extracts of embodiment 1 and comparative example
Fragrant ingredient.
To meet detection sample requirement, the tobacco of embodiment 1 and comparative example 1 is extracted respectively with dichloromethane (polarity 3.4)
Extract, add methylene chloride 200ml per 200ml tobacco extracts, extracts 3 times, merges and collects 3 extract liquor (dichloromethane
Phase), 500ml is taken, is concentrated under reduced pressure (G3 Rotary Evaporators, Heidolph companies), 39 DEG C, vacuum degree 750mbar of thickening temperature, is turned
After fast 110rpm/min, it is concentrated into 2.0ml, obtains detection sample.
Gaschromatographic mass spectrometry condition is as follows：Chromatographic column DB-5MS (30m × 0.25mm × 0.25 μm)；Carrier gas He
(99.999%)；Flow velocity 1.0ml/min；290 DEG C of injector temperature；1.0 μ L of sample size；Sample introduction pattern is split sampling；Shunting
Sample introduction is than 10:1；Temperature program is 45 DEG C (2min), and 5 DEG C/min rises to 200 DEG C, and 3 DEG C/min rises to 250 DEG C, and 5 DEG C/min rises to
300℃(10min)；Ion source is electron bombardment (EI)；Electron energy 70eV；250 DEG C of ion source temperature.Transmission line temperature 300
℃；Analyzer is level four bars mass analyzer；Scan pattern is full scan；40~500amu of mass scan range；Solvent delay
4.5min。
According to gaschromatographic mass spectrometry testing result, analyzes and calculate tobacco extract obtained by every gram of tobacco leaf (oven dry weight)
In several main aroma components mass content and ratio, as shown in table 2 below：
Table 2
As shown in table 2, compared to comparative example 1, main aroma component has increase in the leaf tobacco extract of embodiment 1.Example
Such as, dihydroactinidiolide extraction efficiency increases by 425.9%, and ambreinolide extraction efficiency increases by 154.4%, dimethyl Malaysia
Acid anhydrides extraction efficiency increases by 1225.3%, and succinic anhydride extraction efficiency increases by 204.0%.It follows that being extracted to tobacco leaf
Using after the additive in journey, the extraction efficiency of main aroma component significantly improves.
In addition, for the normalization percentage of above-mentioned several main aroma components, embodiment 1 is compared with comparative example 1, dihydro
The ratio of actinidia lactone and dimethyl maleic anhydride increases, and the ratio of ambreinolide and succinic anhydride decreases.
It follows that the extraction for being not only increased main aroma component using tobacco extract prepared by present composition extraction is imitated
Rate also optimizes the ratio of main aroma component, the tobacco extract be used for cigarette, can effectively be promoted cigarette aroma quality,
Perfume quantity and/or harmony reduce the irritation and/or withered and burnt smell of cigarette, improve Sensory Quality of Cigarette.
Further, according to the detection data of gaschromatographic mass spectrometry, to each aroma component for detecting according to lactone and acid
Two class chemical composition of anhydride carries out Classifying Sum, and specifically, lactone chemical composition includes dihydroactinidiolide, in ambergris
Ester, scopoletin and gamma-butyrolacton；Anhydride chemical composition includes：Dimethyl maleic anhydride, succinic anhydride and phthalic acid
Acid anhydride.
Two class chemical composition contents and ratio comparison are as shown in table 3 below in the tobacco extract of embodiment 1 and comparative example 1.
Table 3
As shown in table 3, in the tobacco extract of embodiment 1, lactone compound extraction efficiency increases in tobacco leaf
154.1%, anhydride compound extraction efficiency increases by 660.4%.From the foregoing, it will be observed that being carried using tobacco prepared by the present composition
Take object, the content of lactone and anhydride two major classes chemical composition is significantly increased in product.
In addition, for the normalization percentage of above-mentioned two major classes chemical composition, embodiment 1 is compared with comparative example 1, lactone
The ratio of compound decreases, and the ratio of anhydride compound increased.It follows that being extracted using the present composition
The tobacco extract of preparation not only increases the extraction efficiency of two major classes chemical composition, also optimizes the ratio of two major classes chemical composition
Example, the tobacco extract are used for cigarette, can effectively promote aroma quality, perfume quantity and/or the harmony of cigarette, reduce cigarette
Irritation and/or withered and burnt smell improve Sensory Quality of Cigarette.
Include lipophilic group and hydrophily base in their chemical constitution for the composition that above-described embodiment uses
Group, wherein lipophilic group can be combined with liposoluble constituent in tobacco leaf, and hydrophilic radical can be combined with water, and then form water packet
The physical form of oil, makes liposoluble constituent in tobacco leaf be dissolved in water.Tobacco is extracted from tobacco using the composition of the present invention
Extract can not only improve the extraction efficiency to effective aroma component and two major classes chemical composition in tobacco, additionally it is possible to excellent
Change the ratio of effective aroma component and two major classes chemical composition.The tobacco extract is used for cigarette, can effectively promote cigarette
Aroma quality, perfume quantity and harmony reduce the irritation and/or withered and burnt smell of cigarette, improve Sensory Quality of Cigarette.
Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
It can modify to the specific implementation mode of the present invention or equivalent replacement is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
