Abstract

The invention discloses a method for reducing cigarette irritancy by using a reed-leaf extract. The extract is greenish black semisolid. The method comprises the following steps of: crushing reed leaves, performing Soxhlet extraction by taking absolute ethyl alcohol as a solvent, and concentrating the obtained extracting solution under reduced pressure to remove ethanol so as to prepare semisolid extract. The extract is dissolved by 95 percent ethanol, and the extract which is 0.01 percent based on the weight of cut tobacco is added into the cigarette so as to obviously reduce the spicy feel and irritancy of cigarette smoke and improve the mouthfeel and quality of the cigarette. The method has the advantages of cheap and readily-available raw materials, simple technology, obvious reduction of the cigarette irritancy, and good industrial application prospect.

Description

Alleviate the irritating method of cigarette with the reed leaf extract

Technical field

The present invention relates to a kind of extraction of reed leaf extract and make an addition to alleviate the irritating method of cigarette smoke in the cigarette.

Background technology

The grass reed Phragmites communisTrin. have another name called: reed, the young shoot of a reed (" Book of Songs "), reed (" not Lu "), giantreed (" medicine to "), cattail and reed (" General Records of Holy Universal Relief "), reed grass (herbal for Relief of Famines), standing grain mix bamboo, water giantreed.Perennial tall and big draft has the shape of crawling subterranean stem, and is sturdy, horizontal walk, internode hollow, tool bud on every joint.

The reed leaf also claims Lu Ye, and another name reed indocalamus is the leaf of reed, and 2 row formulas are arranged, the tool leaf sheath; Leaf sheath is embraced stem, does not have hair or tool fine, soft fur; Leaf celadon or blue-green, broad, the wire lanceolar, long 30～60 centimetres, wide 2～5 centimetres, coarse, tip is point gradually; Long 1～2 millimeter of the tip of a leaf becomes one to take turns a mao shape.Sweet, cold, nontoxic.Pharmacopeia in ancient times such as Compendium of Material Medica, " herbal classic is met former ", " beautiful Chinese catalpa medicine is separated " put down in writing its have control suffer from vomiting and diarrhoea, effect such as haematemesis, bleeding from five sense organs or subcutaneous tissue, lung carbuncle, carbuncle on the back.

Present most reed leaf is used as fuel, and fraction is used for papermaking.Before and after every Dragon Boat Festival, among the people also with its parcel palm fibre, have the unique fragrance flavor.Also there is the people from the reed leaf, to extract flavone compound as the natural food antioxidant.The reed leaf extract makes an addition to and is used to alleviate the irritating application of flue gas in the cigarette, yet there are no report.

Summary of the invention

At the above-mentioned deficiency of prior art, the problem to be solved in the present invention provides and a kind ofly alleviates the irritating method of cigarette with the reed leaf extract, makes the reed leaf extract with the reed leaf, and makes an addition in the cigarette, to alleviate the cigarette smoke excitant.

Technical scheme of the present invention is to extract from the reed leaf to obtain blackish green semisolid extract, makes an addition in the cigarette shreds again, and concrete steps are as follows:

A, the reed leaf was pulverized 30 mesh sieves;

B, the raw material after will pulverizing place apparatus,Soxhlet's, with absolute ethyl alcohol as solvent, and solid-liquid ratio 1:10,100 ℃ of refluxing extraction 6 hours;

C, with the solvent that obtains 53 ℃ of bath temperatures, decompression concentrates and removes ethanol under the condition of vacuum 300mbar, to there being the ethanol flavor, obtains the semisolid extract;

D, above-mentioned semisolid extract is dissolved with 95% ethanol, account for 0.01% of pipe tobacco weight by extract again and add in the cigarette shreds, significantly alleviate the peppery sense of thorn and the excitant of cigarette, improve the mouthfeel quality of flue gas.

Raw material sources of the present invention are extensive, and are with low cost, and method is simple, strong operability.

The specific embodiment

Below in conjunction with embodiment the relevant technologies problem is described in further detail.The applicant has carried out the gas chromatography mass spectrometry analysis to extract, and concrete outcome is as follows:

Used instrument is the HP 6890GC/5973MSD of U.S. Agilent company, and analyze and find that extract contains: terpenoid mainly contains: neophytadiene (Neophytadiene), vitamin E (Vitamin E) etc.; Alcohol compound mainly contains: 9,12,15-18 carbon triolefin-1-alcohol (9,12,15-Octadecatrien-1-ol), 20-methyl-pregnant steroid-5,17-diene-3 β-alcohol (20-Methyl-pregna-5,17-dien-3.beta.-ol), δ 5-ergostenol (.delta.5-Ergostenol), (23S)-ethyl courage steroid-5-alkene-3 β-alcohol ((23S)-ethylcholest-5-en-3.beta.-ol), lanosterol (Lanosterol), α-amyrin (.alpha.-Amyrin), β-amyrin (.beta.-Amyrin), phytol (Phytol), widdrol (Widdrol) etc.; Heterocycle compound mainly contains: 2-(4-methoxyphenyl)-N, N, 2-trimethyl-1-pyrrolidines (2-(4-Methoxyphenyl)-N, N, 2-trimethy l-1-pyrrolamine), N-nornuciferine (N-Nornuciferine), 7-methyl-2,4-diphenyl quinoline (7-methyl-2,4-diphenylquinoline), corymine (Corlumine) etc.; Ester class and lactone compound mainly contain: costunolide (Costunolide), 2-hexadecanoic acid direactive glyceride (2-Hexadecanoyl glycerol), 2-leukotrienes monoglyceride (2-Monolinolenin) etc.; Carbonyls mainly contains: 5-hydroxymethylfurans formaldehyde (5-Oxymethylfurfurole), Syn-1-(right-nitrobenzophenone)-2-(phenyl)-1-(methoxycarbonyl) cyclopropane (syn-1-(p-nitrophenyl)-2-(phenyl)-1-(methoxycarbonyl) cyclopropane), 2,2-dimethyl courage steroid-4-alkene-3-ketone (2,2-dimethylcholest-4-en-3-one), Megastigmatrienone (Megastigmatrienone), aristolone (Aristolone), zierone (Zierone) etc.; The organic acid compound mainly contains: palmitic acid (Palmitic acid), linoleic acid (Linoleic acid), myristic acid (Tetradecanoic acid), stearic acid (Steric acid) etc.

Wherein, (23S)-relative amount of ethyl courage steroid-5-alkene-3 β-alcohol is the highest, reaches 32.58%.

Above-mentioned a lot of compound is flavor component, as: neophytadiene itself has a kind of weak pleasant smell, can promote the jealous and fragrance of tobacco leaf, and can form low molecule aroma component by Degradation and Transformation, also be the important fragrance matter that contains in the tobacco; Phytol is a kind of bioactivator, is the intermediate of preparation vitamin and vitamin, and phytol still is a kind of fragrance component, and delicate fragrance and slight acid are arranged, and adds in the tobacco as flavor component in tobacco; 5-hydroxymethylfurans formaldehyde has the sweet fragrance of a flower, can increase flue gas concentration; Megastigmatrienone has cocoa aroma, can increase the comfortable mouthfeel of flue gas, improves the fragrance of side-stream smoke; Palmitic acid, linoleic acid, myristic acid are the higher fatty acids of certain fragrance, and it is of poor quality and make it have light sweet soft suction flavor to improve flue gas.

The applicant is with certain trade mark cigarette, with aforementioned extract with the dissolving of 95% ethanol after, respectively with 5/100000ths, ten thousand of pipe tobacco weight/, ten thousand/slender acanthopanax goes in the cigarette shreds, simultaneously the equivalent solvent is added in the pipe tobacco as blank.Compare behind the cigarette balance 48h after adding and smoke panel test.Smoke panel test through the specialty personnel that smoke panel test, the result is as shown in table 1.

The different addition smoking results of table 1 extract

Extract addition/pipe tobacco weight (%)	Smoking result
		0.005	The satisfaction of flue gas promotes to some extent, and excitant alleviates to some extent, but the fine and smooth sense decline of fragrance, assorted gas increases, and all the other do not have obviously improvement.
0.01	Mouthfeel quality obviously improves, and stings peppery sense and obviously alleviates, and the flue gas excitant obviously alleviates.
		0.05	Mouthfeel quality has improvement slightly, and stinging peppery sense has slightly and alleviate, but assorted gas increases obviously.

From the smoking result of table 1 as can be seen, the addition of extract is 0.01% o'clock of pipe tobacco weight, can significantly alleviate the peppery sense of thorn and the excitant of cigarette, improves the mouthfeel quality of flue gas.
