Definitions
- the present invention relates to the use of polyphenolic compounds or their derivatives as free radical scavengers in cigarette filters.
- polyphenolic compounds are known for their beneficial properties in fields as varied as hypertension, high cholesterol, involved in cardiovascular disease, viral infections, or even inflammatory phenomena.
- the anti-lipoperoxidizing and anti-carcinogenic activities of certain polyphenols have also been described.
- the present invention therefore relates to the use of polyphenolic compounds as scavengers for free radicals in cigarette filters.
- the polyphenols used in accordance with the present invention can be chosen from camosol, rosmanol, rosmarinic acid, carnosic acid, and their derivatives.
- derivatives in particular the compounds deriving from polyphenolic compounds by substitution of the hydrogen atom of at least one of the hydroxy groups of the polyphenolic compounds by a C1-C6 alkyl group, or a group (C1-C4 alkyl). 1 -C 4 ) carbonyl.
- Acetates such as acetates of carnosic acid and acetates of acid rosmarins are preferred derivatives of the polyphenolic compounds used in accordance with the invention.
- derivatives of the polyphenols used in accordance with the invention such as camosol, rosmanol, rosmarinic acid, carnosic acid, is also meant the isomers of said polyphenols such as in particular epirosmanol and isorosmanol (Nakatani and al., Agric. Biol. Chem., 1984, vol.
- Said polyphenols can also be used according to the present invention in the form of a plant extract, preferably a plant extract from the Labiate family, such as in particular a rosemary extract (Rosmarinus officinalis L).
- a plant extract preferably a plant extract from the Labiate family, such as in particular a rosemary extract (Rosmarinus officinalis L).
- Such a plant extract can be obtained by extraction with a polar solvent such as an alcoholic or hydro-alcoholic solvent.
- a polar solvent such as an alcoholic or hydro-alcoholic solvent.
- the alcohol used as solvent can in particular be ethanol.
- This extract can also advantageously be obtained using supercritical carbon dioxide and is therefore richer in polyphenolic compounds.
- the plant extract used according to the invention can be obtained by extraction with a polar solvent followed by an extraction with supercritical CO 2 .
- Rosemary extraction is preferably carried out on dried plants, for example on branches of rosemary, cut and dried in the sun for 4 to 5 days.
- polyphenolic compounds or their derivatives obtained by chemical synthesis, by biotechnological route, or by extraction from plants, can be used alone or as a mixture in accordance with the invention.
- a mixture of camosol, carnosic acid and rosmarinic acid can be advantageously used.
- the polyphenolic compounds or their derivatives can be used in free form or can be conjugated or coupled to a support ("carrier") making it possible to increase the weight of the whole polyphenols-support.
- Microbeads can in particular serve as a support. They can for example be made of plastic (polystyrene or other) or glass.
- the polyphenolic compounds can be incorporated into cigarette filters at a rate of 0.5 mg to 0.5 grams, preferably 0.002 to 0.1 grams, preferably 0.01 grams.
- a solvent it is advantageous to soak the cigarette filter with said solvent containing the polyphenols and then proceed with the evaporation of said solvent.
- the cigarette filter can be soaked with an alcoholic or hydroalcoholic plant extract and then subjected to evaporation of the alcoholic or hydroalcoholic solvent.
- the polyphenolic compounds or their derivatives can also be dissolved in a saturated oil, and thus incorporated into the filter of the cigarette.
- the invention also relates to a process for the preparation of a cigarette filter in which polyphenolic compounds chosen from camosol, rosmanol, rosmarinic acid, carnosic acid and their derivatives are incorporated into said cigarette filter.
- the invention also relates to a cigarette filter obtained by the above process.
- a filter makes it possible to reduce the quantity of free radical molecules present in cigarette smoke.
- the authors of the present invention have discovered that the polyphenols or their derivatives incorporated into the filter of a cigarette capture the free radicals of the cytotoxic molecules present in cigarette smoke, both in the aqueous phase and in the solid phase of the smoke. , which consists mainly of tars. These cytotoxic molecules promote the appearance of cancers in smokers, in particular lung cancer.
- Polyphenols or their derivatives incorporated into the filter of a cigarette also exhibit, on the one hand, an inhibition of the activity of carcinogenic compounds, by reduction of the formation of heterocyclic amines, during the combustion of tobacco and, d on the other hand, a detoxification of carcinogenic compounds, such as benzopyrene.
- the appended figure is a graph representing the signal intensity, in electronic paramagnetic resonance, of the terbutyloxy radicals in the gas phase of cigarette smoke as a function of the quantity of rosemary extract incorporated into the filter.
- Rosemary (Rosmahn ⁇ s officinalis L.) ears are extracted with ethanol at 65 ° C.
- the volume of ethanol used (in liters) corresponds to five times the weight in kg of rosemary ears.
- the extract is then purified and enriched in polyphenols by selective extraction with supercritical CO 2 .
- the extract is purified and selectively enriched in its various components.
- Such an extract contains the following compounds: - camosol,
- an extract comprising approximately 25% of rosmarinic acid, approximately 10% of carnosic acid and approximately 5% of camosol.
- a cigarette filter is soaked with either the prepared extract, the ethanol then evaporated, or an oily phase based on CRODAMOL® (French Aromas and Perfumes), in which is dissolved a powder obtained by drying the extract prepared above.
- CRODAMOL® Frnch Aromas and Perfumes
- Computer-assisted modeling The effectiveness of the cigarette filter thus prepared is first demonstrated by computer-assisted modeling, according to the Monte-Carlo method, which makes it possible to calculate the number of encounters between a target molecule carcinogen and a polyphenolic compound used in accordance with the invention.
- the number of free radical cytotoxic molecules present in cigarette smoke was calculated on either side of the filter.
- the number of cytotoxic molecules is a function of the volume of smoke passing through the filter, the volume of the filter, the concentration of cytotoxic molecules in the smoke and the concentration of polyphenols in the filter.
- the authors of the present invention have thus shown that 0.01 g of the rosemary extract incorporated in the filter of a cigarette makes it possible to reduce by more than 70% the level of molecules with free cytotoxic radicals in cigarette smoke.
- EPR is a technique for studying paramagnetic substances directly or indirectly.
- Paramagnetic compounds are molecules with a single unpaired electron on their last valence layer. Such substances are designated by the term radicals.
- radicals When these radicals have very short lifetimes (much less than a second) it is advantageous to use the so-called "spin trapping" technique. It consists in using trappers capable of stabilizing the radicals produced by the formation of an adduct and thus of measuring them for several minutes. This reaction is done as follows:
- DMPO 5.5 'dimethyl pyrroiine-N-oxide
- Anti-free radical activity on the radicals produced in the gas phase of cigarette smoke The device for trapping radicals in the gas phase of cigarette smoke is described in Pryor et al, Environmental Health Perspectives, 1976, vol.16, pp 161-175.
- a cigarette is placed at the end of such a device, and the gas phase of the smoke, after passing through a Cambridge filter (finer than a cigarette filter to retain tar), is dissolved in a benzene "spin trap" solution.
- the DMPO is adjusted to a concentration of 32 mM in a benzene solution and the gas phase of two cigarettes is used.
- the radical mainly present in these tars and responsible for a carcinogenic activity well established to date, is of semiquinonic nature. This semiquinone which has a long lifespan will be able to react within cells and thus produce deleterious species such as oxygen radicals.
- the decrease in signal indicates that the rosemary extract has a higher radical scavenging speed than DMPO (see figure).
- the filter was impregnated with 250 ⁇ l of the lipid phase based on CRODAMOL®, containing 10 mg / ml of dry rosemary extract powder.
