Description
Oppfinnelsen vedrører substanser som er nyttige som aromastof f er, mer spesielt som røk-aroarastoffer for tobakk, rekonstituert tobakk og tobakk-erstatninger, med hvilket det menes materialer som, selv om de ikke er av tobakk-opprinnelse, er røkbare på samme måte som sigaretter, sigarer, piper osv. The invention relates to substances which are useful as aroma substances, more particularly as smoke aroma substances for tobacco, reconstituted tobacco and tobacco substitutes, by which is meant materials which, although not of tobacco origin, are smokable in the same way as cigarettes, cigars, pipes, etc.
Det er blitt fremsatt forslag angående erstatning av tobakk med substitutter for denne fordi tobakksrøk er kjent å være produktiv når det gjelder sykdommer i bronkiene og lungene. De kjente substitutter er, til tross for forbedrede helsekarakteristika i sammenligning med tobakk, av begrenset verdi på grunn av sin røkearoma som ikke ligner tobakk. For å gi en uttalt grad av tobakkaroma har det hittil vært nød-vendig med innblanding av store andeler av tobakk og/eller ekstrakter av tobakk, hvorved de oppnåelige sunnhetsmessige fordeler reduseres. Proposals have been made regarding the replacement of tobacco with substitutes for it because tobacco smoke is known to be productive in diseases of the bronchi and lungs. The known substitutes, despite improved health characteristics compared to tobacco, are of limited value due to their smoke aroma which does not resemble tobacco. In order to give a pronounced degree of tobacco aroma, it has hitherto been necessary to mix in large proportions of tobacco and/or extracts of tobacco, whereby the achievable health benefits are reduced.
Oppfinnelsen tilveiebringer en substans som omfatter et glykosyloksyderivat av en 4-(2,6,6-trimetylcykloheksan-l-yl)-butanforbindelse med den generelle formel The invention provides a substance comprising a glycosyloxy derivative of a 4-(2,6,6-trimethylcyclohexan-1-yl)-butane compound of the general formula
hvor enten karboksylringen eller den fireleddede sidekjede eller begge disse er av umettet karakter og molekylet kan bære som ytterligere substituenter metylgrupper, en ketogruppe og/eller en hydroksylgruppe. where either the carboxyl ring or the four-membered side chain or both of these are of an unsaturated nature and the molecule can carry as additional substituents methyl groups, a keto group and/or a hydroxyl group.
Det skal forståes at ovenstående formel, og alle andre formler som angis i det følgende, er konvensjonelle og at med mindre muligheter for umettethet og substitusjon på annen måte er angitt, representerer hver vinkel eller utilknyttet linje et karbonatom med sine fire valenser mettet enten på den måte som er angitt, eller ved tilknyttede hydrogenatomer. It is to be understood that the above formula, and all other formulas set forth below, are conventional and that unless possibilities of unsaturation and substitution are otherwise indicated, each angle or unconnected line represents a carbon atom with its four valences saturated either on the manner indicated, or by attached hydrogen atoms.
I en første utførelsesform tilveiebringer oppfinnelsen en substans som omfatter et glykosid av formelen In a first embodiment, the invention provides a substance comprising a glycoside of the formula
hvor ringen A inneholder én dobbeltbinding i de alternative posisjoner vist ved stiplede linjer og den fireleddede sidekjede kan inneholde én dobbeltbinding i de alternative posisjoner som er vist ved stiplede linjer, ett av radikalene R2og R4er en giykosyloksygruppe -0X hvor X er radikalet av et mono- eller disakkarid,<R>2,R- og R4kan alternativt representere -H, «0eller -0H (forutsatt at R^ og R4ikke samtidig representerer =0), og Rg representerer alternativt -H, -OB eller null. Det skal naturligvis forståes at alle variable i formel IX er underkastet den begrensning at karbonatomer ikke kan ha en valens større enn 4. Således for eksempel, idet tilfelle hvor en dobbeltbinding er beliggende mellom karbonatomer merket 1 og 2 i ring A, er symbolet Rg null og bare en enkeltbinding forbinder ringkarbonatomet med nummer 1 med sidekjede-karbonatoraet med nummer 4. I en annen utførelsesform tilveiebringer oppfinnelsen en substans som omfatter et glykosid av formelen where the ring A contains one double bond in the alternative positions shown by dashed lines and the four-membered side chain may contain one double bond in the alternative positions shown by dashed lines, one of the radicals R2 and R4 is a giycosyloxy group -OX where X is the radical of a mono- or disaccharide, <R>2, R- and R4 may alternatively represent -H, «0 or -OH (provided that R1 and R4 do not simultaneously represent =0), and Rg alternatively represent -H, -OB or zero. It should of course be understood that all variables in formula IX are subject to the restriction that carbon atoms cannot have a valency greater than 4. Thus, for example, in the case where a double bond is located between carbon atoms marked 1 and 2 in ring A, the symbol Rg is zero and only a single bond connects the ring carbon atom with number 1 to the side chain carbonator with number 4. In another embodiment, the invention provides a substance comprising a glycoside of the formula
hvor ett av symbolene Y representerer radikalet av et mono-eller disakkarid* where one of the symbols Y represents the radical of a mono- or disaccharide*
Søkeren har identifisert glukosider med formel II og XII (hvor glykosyl-radikalene representert ved henholdsvis X og Y er glukosyl-radikaler) som bestanddeler i tobakk, hvor The applicant has identified glucosides of formulas II and XII (where the glycosyl radicals represented by X and Y respectively are glucosyl radicals) as constituents of tobacco, where
de er til stede i uvanlig små mengder. they are present in unusually small amounts.
Sterkt konsentrerte preparater, inneholdende for eksempel 25 vekt% eller mer av glukosidene, kan oppnås fra Highly concentrated preparations, containing for example 25% by weight or more of the glucosides, can be obtained from
tobakk, én fremgangsmåte for oppnåelse av slike preparater omfatter ekstrahering av tobakk med et lavtkokende ketonisk tobacco, one method of obtaining such preparations involves the extraction of tobacco with a low-boiling ketonic
løsningsmiddel, for eksempel aceton, suksessiv fjerning fra ekstraktene av de deler som er løselige i alifatisk hydrokarbon, for eksempel heksan, og deretter et lavtkokende klorert hydrokarbon, for eksempel kloroform, og oppnåelse av en vannløselig fraksjon fra residuet, og den vandige løs-ning derav utsettes for behandling med ionebytte-harpikser for fjerning av basiske og sure fraksjoner, slik at man får et nøytralt residuum, hvoretter residuet ekstraheres med en lavere alkanol, spesielt butanol, og løsningen utsettes for gelpermeabilitets- og væskekromatografi for gjenoppløsning av det i fraksjoner som er rikt på individuelle glukosider. solvent, for example acetone, successive removal from the extracts of the parts soluble in aliphatic hydrocarbon, for example hexane, and then a low-boiling chlorinated hydrocarbon, for example chloroform, and obtaining a water-soluble fraction from the residue, and the aqueous solution thereof is subjected to treatment with ion-exchange resins to remove basic and acidic fractions, so that a neutral residue is obtained, after which the residue is extracted with a lower alkanol, especially butanol, and the solution is subjected to gel permeability and liquid chromatography to redissolve it into fractions which is rich in individual glucosides.
Glukosidene i henhold til oppfinnelsen finnes hovedsakelig i de tidligere eluerte fraksjoner fra gelpermeabilitets-separaSjonen, og fra disse kan individuelle, rene glukosider isoleres ved væskekromatografi om så ønskes. Den sist eluerte The glucosides according to the invention are mainly found in the previously eluted fractions from the gel permeability separation, and from these, individual, pure glucosides can be isolated by liquid chromatography if desired. The last eluted
fraksjon fra gelpermeabilitet inneholder hovedsakelig glukosider av en annerledes natur, hvorav noen er beskrevet i søkerens britiske patentskrifter nr. fraction from gel permeability mainly contains glucosides of a different nature, some of which are described in the applicant's British patent documents no.
(Søknader 32288/75 og 47454/75). Separasjonsteknikken som søkeren har benyttet seg av, er mer spesielt beskrevet i eksemplene. (Applications 32288/75 and 47454/75). The separation technique used by the applicant is more specifically described in the examples.
Ved hvert trinn i prosessen blir den tobakkaroma som produseres ved forbrenning av fraksjonen, mer utpreget. At each step in the process, the tobacco aroma produced by burning the fraction becomes more pronounced.
De endelige glukosider er, når de er i ialt vesentlig ren form, farveløse, faste stoffer. De er blitt tilskrevet kjemiske strukturer ved hjelp av<13>C NMR (kjernemagnetisk resonans)-spektroskopi og ved enzymatisk hydrolyse til de tilsvarende aglykoner, inneholdende -OH-grupper istedenfor glukosyloksy-gruppene, gg disse er blitt isolert som farve-løse oljer. The final glucosides, when in substantially pure form, are colorless solids. They have been attributed to chemical structures by <13>C NMR (nuclear magnetic resonance) spectroscopy and by enzymatic hydrolysis to the corresponding aglycones, containing -OH groups instead of the glucosyloxy groups, and these have been isolated as colorless oils.
13 13
C NMR-spektroskopi og PMR (proton-magnetisk resonans)-spektroskop! er også blitt anvendt for bestemmelse av strukturen til aglykonene, som generelt er kjente forbindelser, I aglykonene produserer gem-dimetyl-gruppen på karbonatom nummer 6 karakteristisk en PMR-resonans som oppviser to 3-proton-singletter i området 0,95-1,30 ppm i forhold til tetrametylsilan C NMR spectroscopy and PMR (proton magnetic resonance) spectroscope! has also been used for determining the structure of the aglycones, which are generally known compounds. In the aglycones, the gem-dimethyl group on carbon atom number 6 characteristically produces a PMR resonance showing two 3-proton singlets in the range 0.95-1, 30 ppm in relation to tetramethylsilane
(IMS) . (IMS).
Som et trekk som kan definere forbindelsene i henhold til oppfinnelsen, er derfor glykosidene hydrolyserbare enzymatisk til aglykoner som har det ovenfor nevnte PMR-spektrum-karakteristikk. As a feature that can define the compounds according to the invention, the glycosides are therefore enzymatically hydrolyzable to aglycones which have the above-mentioned PMR spectrum characteristic.
Olykosider i henhold til oppfinnelsen er oppnåelige syntetisk under anvendelse som utgangsmaterialer av et mono-eller disakkarid (spesielt glukose) og et hydroksyderivat av det aktuelle 4-(2,6,6-triraetylcykloheksan-l-yl)butanforbindelse (aglykon)• Således kan mono- eller disakkarider O-acyleres og omdannes til et funksjonelt derivat, for eksempel et halogenid, som er reaktivt overfor hydroksylgrupper, deretter omsettes med hydroksyforbindeIsen og O-acylgruppene i produktet ble hydrolysert. Spesielt kan glukose omdannes til tetraacetoksy-glukosylbromid som kan kondenseres med hydroksy-4-(2,6,6-trimetylcykloheksan-l-yDbutan, og acetylgruppene hydrolyseres for å gi glukosidet. Olycosides according to the invention are obtainable synthetically using as starting materials a mono- or disaccharide (especially glucose) and a hydroxy derivative of the relevant 4-(2,6,6-triraethylcyclohexan-l-yl)butane compound (aglycon) mono- or disaccharides are O-acylated and converted into a functional derivative, for example a halide, which is reactive towards hydroxyl groups, then reacted with hydroxy compounds and the O-acyl groups in the product were hydrolysed. Specifically, glucose can be converted to tetraacetoxy-glucosyl bromide which can be condensed with hydroxy-4-(2,6,6-trimethylcyclohexane-1-yDbutane) and the acetyl groups hydrolyzed to give the glucoside.
Foretrukne glykosider stammer fra heksoser eller pentoser, idet glukosider spesielt foretrekkes. Preferred glycosides are derived from hexoses or pentoses, glucosides being particularly preferred.
Spesifikke eksempler på det foretrukne glukosider Specific examples of the preferred glucosides
er forbindelsene av de følgende formlers are the compounds of the following formulas
hvor G representerer en Ø-D-glukosylgruppe. where G represents an Ø-D-glucosyl group.
Substansene i henhold til oppfinnelsen gir en distinkt tobakkaroraa til røken fra tobakk-eubetitutter som ellers ville The substances according to the invention give a distinct tobacco aroma to the smoke from tobacco eubetitutes which would otherwise
være helt blottet for slik aroma. Bare små andeler, for eksempel 1 vekt%, er nødvendig for å gi en slik effekt; Dette er visselig bemerkelsesverdig da substansens selv ikke er flyktige. Videre gir agiykonene som de er oppnåelige fra, liten eller ingen tobakkrøk-aroma til tobakk-substitutter. be completely devoid of such aroma. Only small proportions, for example 1% by weight, are necessary to produce such an effect; This is certainly remarkable as the substances themselves are not volatile. Furthermore, the agiykons from which they are obtainable impart little or no tobacco smoke flavor to tobacco substitutes.
Selv om de syntetiske glykosider utgjør et spesielt trekk, inkluderes også innen oppfinnelsens ramme aromasettende substanser i form av konsentrater som er isolert fra tobakk, idet slike konsentrater for eksempel inneholder minst 25 % av . de tidligere angitte glukosider. Om ønskes, kan substansene i henhold til oppfinnelsen ' også bli anvendt for å forbedre eller styrke tobakkaromaen, spesielt for rekonstituert tobakk eller blandinger av tobakk og tobakk-substitutter. Although the synthetic glycosides constitute a special feature, the scope of the invention also includes flavoring substances in the form of concentrates isolated from tobacco, such concentrates for example containing at least 25% of . the previously indicated glucosides. If desired, the substances according to the invention can also be used to improve or strengthen the tobacco aroma, especially for reconstituted tobacco or mixtures of tobacco and tobacco substitutes.
I henhold til et ytterligere trekk ved oppfinnelsen tilveiebringes derfor røkematerialer som omfatter tobakk (inklusive rekonstituert tobakk), tobakkerstatning eller en blanding av tobakk med en tobakkerstatning, og som er tilsatt en liten vektandel, for eksempel 1 %, av en substans som definert i det foregående. According to a further feature of the invention, smoking materials are therefore provided which comprise tobacco (including reconstituted tobacco), tobacco substitute or a mixture of tobacco with a tobacco substitute, and to which is added a small proportion by weight, for example 1%, of a substance as defined in the preceding.
Tobakk-substitutter kan for eksempel være basert på materialer av karbohydratopprinnelse, for eksempel slike materialer som er beskrevet i de britiske patentskrifter 1.055.473 og 1.143.500 samt i US-patentskrift 3.106.209, nem-lig cellulose, oksydert cellulose eller salatblader. Cellulose-etere kan også anvendes. Modifiserte karbohydrater foretrekkes, idet betegnelsen "modifisert" betyr kjemisk modifisert og inne-bærer at det opprinnelige karbohydrat har gjennomgått en for-andring av kjemisk natur. Tobacco substitutes can, for example, be based on materials of carbohydrate origin, for example such materials as are described in British patents 1,055,473 and 1,143,500 as well as in US patent 3,106,209, namely cellulose, oxidized cellulose or salad leaves. Cellulose ethers can also be used. Modified carbohydrates are preferred, as the term "modified" means chemically modified and implies that the original carbohydrate has undergone a change of a chemical nature.
Tobakkerstatningen kan med fordel være et varmened-brutt karbohydrat, laget for eksempel ved å utsette karbohydrat (spesielt cellulose) for en katalysert nedbrytningsprosess ved en temperatur over 100°C (for eksempel 100-250°C som angitt i søkerens britiske patent 1.113.979, eller over 250° som angitt i søkerens britiske patent 1.415.893) inntil vekten av nedbrutt karbohydrat er mindre enn 90 % av vekten av det opprinnelige karbohydrat. En lignende substans er oppnåelig som beskrevet i søkerens britiske patentskrift 1.289.354 ved syre- eller base-katalysert kondensering av en forbindelse av formelen The tobacco substitute can advantageously be a heat-degraded carbohydrate, made for example by subjecting carbohydrate (especially cellulose) to a catalyzed decomposition process at a temperature above 100°C (for example 100-250°C as stated in the applicant's British patent 1,113,979 , or above 250° as stated in the applicant's British patent 1,415,893) until the weight of degraded carbohydrate is less than 90% of the weight of the original carbohydrate. A similar substance is obtainable as described in the applicant's British patent specification 1,289,354 by acid- or base-catalyzed condensation of a compound of the formula
12 12
hvor R og R , som kan være like eller forskjellige, hver representerer et hydrogenatom eller en alkyl-, hydroksyalkyl-eller formyl-gruppe eller en forløper for en slik forbindelse where R and R , which may be the same or different, each represent a hydrogen atom or an alkyl, hydroxyalkyl or formyl group or a precursor of such a compound
(II). (II).
Substansene i henhold til oppfinnelsen kan innarbeides The substances according to the invention can be incorporated
i røkematerialene i henhold til oppfinnelsen på enhver bekvem måte. Andre kjente ingredienser i røkematerialer kan inkluderes for tilføring av fysikalske egenskaper og brennekarakteristika.

For fremstilling av slike ark kan ingrediensene i rØkematerialet, for-trinnsvis sammen med tobakken eller tobakkerstatningen i fin-delt form, blandes med en tilstrekkelig mengde av vann til å produsere en oppslemming som deretter støpes på en flate og tørkes. Arkmateriale som fremstilles av oppslemmingen, kan trevles opp slik at man får et materiale i en form som er egnet for røkning. The smoking materials according to the invention are usually produced in sheets, containing a film-forming agent, for example a natural gum or pectin or a cellulose ether, especially carboxymethyl cellulose or a salt thereof. For the production of such sheets, the ingredients of the smoking material, preferably together with the tobacco or tobacco substitute in finely divided form, can be mixed with a sufficient amount of water to produce a slurry which is then poured onto a surface and dried. Sheet material produced from the slurry can be unraveled so that a material is obtained in a form suitable for smoking.
De foretrukne røkematerialer i henhold til oppfinnelsen er slike som er basert på tobakkerstatninger og mer spesielt på varraenedbrutte karbohydrater som tidligere definert. Slike røkematerialer i henhold til oppfinnelsen gir røk som inneholder relativt små andeler av skadelige ingredienser, og da de i seg selv har en distinkt tobakkaroma, hører det med til oppfinnelsen at de kan blandes sted tobakk i relativt store andeler for til- The preferred smoking materials according to the invention are those which are based on tobacco substitutes and more particularly on varra-degraded carbohydrates as previously defined. Such smoking materials according to the invention provide smoke that contains relatively small proportions of harmful ingredients, and as they themselves have a distinct tobacco aroma, it is part of the invention that they can be mixed instead of tobacco in relatively large proportions for
