Definitions
- the present invention relates to a process for obtaining a plant extract of avocado leaves rich in furan lipids.
- the avocado comprises, in a known manner, specific lipids of the furan type, the main component of which is a linoleic furan:
- R is a linear C 11 -C 19 hydrocarbon chain, preferably C ⁇ 3 -C ⁇ 7 saturated or comprising one or more ethylenic or acetylenic unsaturations.
- the Applicant has thus perfected a process, making it possible to obtain a vegetable extract of avocado leaf rich in furan lipids, namely with a content varying from 20 to 80% and preferably 30 to 50%.
- This process the raw material of which consists of avocado leaves, comprises the following stages:
- the avocado leaves can come from avocados belonging to the following varieties: Hass, Fuerte, Ettinger, Bacon, Nabal, Anahe ⁇ m, Lula, Reed, Zutano, Queen, Criola Selva, Mexicana Canta, Region Dschang, Hall,. Booth, Peterson, Collinson Red or Alpha Krome and more advantageously the Hass, Fuerte and Reed varieties.
- Several solvents can be used during the liquid-solid extraction step of the leaves, having possibly previously undergone dehydration.
- the solvents can be chosen from the group consisting of alkanes, halogenated alkanes, ethers, esters, alcohols, aromatic compounds and supercritical fluids. Preferred, alone or as a mixture, hexane, ethanol, methanol, chloroform, dichloroethane, and ethyl acetate.
- the heat treatment step is carried out at temperatures between 80 and 120 ° C. This heat treatment can last from 5 to 72 hours.
- the heat treatment step can be carried out in the presence or not of an acid catalyst.
- Acid catalysts in the broad sense are understood to be so-called homogeneous inorganic and organic catalysts such as hydrochloric, sulfuric, acetic or paratoluenesulfonic acids but also, and preferably, heterogeneous solid catalysts such as silica, alumina, silica-aluminas , zirconia, zeolites, acid resins.
- acid aluminas with large specific surfaces will be chosen, that is to say at least equal to 200 m 2 / g.
- the process can also include a step, prior to the liquid-solid extraction, of dehydrating the avocado leaves.
- dehydration of avocado leaves is understood more generally to mean all of the techniques known to the skilled person and which make it possible to extract water from a compound. Among these techniques, mention may be made of drying under a stream of hot air or under a controlled atmosphere (eg nitrogen), at atmospheric pressure or under vacuum, in a thick or thin layer, but also drying by microwaves, drying by spraying, lyophilization and osmotic dehydration in solution (direct osmosis) or in solid phase (eg drying in osmotic bags).
- the temperature during this dehydration stage will preferably be maintained, whatever the technique used, less than or equal to 80 ° C.
- the present invention it is preferred in the context of the present invention to stop dehydration when the residual humidity reaches the threshold of 5%.
- drying in ventilated dryers in a thin layer and under a stream of hot air, at a temperature of between 70 and 75 °. It is preferred.
- the duration of the operation can vary from 5 to 72 hours.
- the method is implemented according to the following succession of steps:
- Step 1 heat treatment of avocado leaves
- Step 2 liquid-solid extraction of avocado leaves
- Step 3 evaporation of the solvent under vacuum until a desolvented plant extract is obtained.
- the method is implemented according to the following succession of steps:
- Step 2 evaporation of the solvent under vacuum until a desolvented plant extract is obtained
- the method is implemented according to the following succession of steps:
- Step 3 evaporation of the solvent under vacuum until a plant extract is obtained
- the sheets are advantageously ground before any operation carried out within the framework of the process of the invention.
- the present invention finally relates to a plant extract of avocado leaves capable of being obtained by the process according to the invention, including according to all of its variants.
- Example 1 one kilogram of avocado leaves of the Hass variety is carefully ground.
- the ground material obtained (320 g) is brought into contact with 2 liters of ethanol and then brought to reflux for 5 hours. Once cooled, the mixture is filtered through a buchner and the cake washed with three times 100 ml of ethanol.
- the solvent is then evaporated in vacuo using a rotary evaporator, then drawn under vacuum for another hour after total removal of the solvent.
- the extract obtained is then placed in an oven at 100 ° C for 24 hours, then analyzed. 23 g of extract are obtained according to this process.
- Example 2 one kilogram of avocado leaves of the Fuerte variety is carefully ground.
- the ground material obtained (305 g) is brought into contact with 2 liters of hexane and then brought to reflux for 5 hours. Once cooled, the mixture is filtered through a buchner and the cake washed with three times 100 ml of hexane. Once gathered, the hexane phases are dried in the presence of Na 2 S0 4 .
- the hexane is then evaporated under vacuum using a rotary evaporator, then drawn under vacuum for a further hour after complete removal of the solvent.
- the extract obtained is then placed in an oven at 100 ° C for 24 hours, then analyzed. 26 g of extract are obtained according to this process.
- Incineration residue ⁇ 0.1% Volatile content: ⁇ 0.1% Furanic lipid content: 46%
- Example 3 one kilogram of avocado leaves of the Hass variety is carefully ground. The ground material is brought into contact, with stirring, for 5 hours, with 10 liters of methanol, 10 liters of chloroform and 10 liters of salt water (1% NaCl). The mixture is then centrifuged and the solid pellet removed. The lower liquid phase is recovered and then dried over Na 2 S0. The solvents are then evaporated in vacuo using a rotary evaporator, then drawn under vacuum for another hour after total removal of the solvents. The extract obtained is then placed in an oven at 100 ° C for 24 hours, then analyzed. 21 g of extract are obtained according to this process.
- Example 4 one kilogram of avocado leaves of the Hass variety is carefully ground. The ground material is then dried in an oven, under a stream of hot air, at 110 ° C for 24 hours. 302 g of dry matter are then recovered. The latter is then brought into contact with 2 liters of hexane and then brought to reflux for 5 hours. Once cooled, the mixture is filtered through a buchner and the cake washed with three times 100 ml of hexane. The hexane is then evaporated under vacuum using a rotary evaporator, then drawn under vacuum for a further hour after complete removal of the solvent. 31 g of extract are obtained according to this process.
- Example 5 one kilogram of Hass variety avocado leaves is carefully ground. The ground material is then dried in an oven, under a stream of hot air, at
- Incineration residue ⁇ 0.1% Volatile content: ⁇ 0.1% - Furan lipid content: 2%
