    Anthraquinone extraction procedure from aloe to repel insects. Object of the invention
    The present invention relates to a method of extracting anthraquinones from aloe to prepare an insect repellent product on vegetables, animals, people and objects.
    The Aloe Vera variety (Aloe Barbadensis Miller) has the most anthraquinones in relation to the weight of the leaf that contains it, although the extraction procedure is valid for any variety of aloe (arborescens, chinensis, socrotrino, ferox, saponarea, latifolia, etc.).
    An aloe leaf is made up of the bark in which anthraquinones are found, except for aloin; the sap (also called acíbar} in which the aloin is found, in greater proportion and anthraquinones, in a smaller proportion, yellowish and very bitter; and the inner part (also called aloe) in which the color gel is found crystalline.The aloe anthraquinones are: aloin, barbaloin, isobarbaloin, anthranol, anthracene, aloeic acid, cinnamic acid, ethereal oils, emodin, resistanoles, aloe emodin, chloratanic acid and cinnamic acid esters.They have bactericidal, antiviral, analgesic properties. , fungicides and laxatives.
    Its repellent action is due both to its bitter taste and its unpleasant smell. The contribution to this flavor and smell of the product is due to anthraquinone-aloin in 80% and the rest of anthraquinones in approximately 20%.
    The persistence of the product on vegetables can be estimated between 7-8 days, on animals 6-7 hours and on people 6-7 hours.
    The effectiveness of the product on vegetables, animals, people and objects is 100%, using different dosages for each type of insects (mosquitoes, ants, spiders, etc.).
    The advantages of this invention are the following:
    - It is insect repellent: to all kinds of vegetables (trees, hedges, grass, bushes, shrubs, plants, etc.), applying the product through a spray system; to certain animals (dogs, cats, pigs, horses, cows, etc.), applying the product through conventional systems on the skin; and to all people (babies, children, pregnant women, adults and the elderly), applying the product through conventional systems on the skin.
    - It can be applied spray (atomizer, backpack spray, etc.) and by more conventional means (spray, roll on, etc.).
    - It is totally ecological because it does not contain any type of chemical added and because it is not necessary to apply to the plant any type of pesticide for its development, since the plant itself is repellent of insects and other possible predators.
    - It is respectful with the environment, since it is not toxic to vegetables, animals and people.

    - Any individual can spray the product since it is not toxic and does not irritate the skin or eyes.
    - The product can be sprayed in any public enclosure (park, camping, hotel, rural house, swimming pool, etc.), without the need to evict it.
    The industrial application of this invention is within the sector of manufacturing insect repellent products and more specifically those obtained through the extraction of anthraquinones from aloe. Background of the invention
    Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related to it.
    Thus, document ES2322179T3 refers to a method to repel pests of a plant, where the plant is treated with a natural insect repellent composition that contains at least garlic and / or an extract thereof and algae and / or an extract thereof , where the method comprises making a hole to the root zone of the plant and putting the natural insect repellent composition in that hole. There is no reference to aloe in the repellent composition at any time.
    ES2039246T3 proposes a mosquito repellent composition, comprising: - an effective amount of a chemical agent; - at least 2 percent by weight, based on said active agent, of an acrylate polymer, water insoluble and oil soluble, having a solubility parameter of 6 to 10 (ca / cm3) 1/2 in solvents that bind poorly with hydrogen and a Brookfield viscosity between approximately 50 and 250,000 cps, measured at 25 percent non-volatile components; and - a liquid vehicle. Again, the components of the aloe proposed by the main invention are not mentioned.
    ES2318496T3 proposes an emulsion formulation for topical application on the skin comprising: an aqueous phase, an oil phase, at least one emulsifier, a copolymer of ethylene diamine / neopentyl glycol / stearyl hydrogenated dimer dilinoleate and at least one active agent of Sun screen. This topical application does not refer to repel insects or make use of aloe in its composition.
    ES2187197T3 describes a use of at least one perfume ingredient selected from the group consisting of tricyclodecenyl-allyl ether, 2- (2-methylpropyl) -4-hydroxy-4-methyltetrahydropyran, N-methyl-N-phenyl-2-methylbutanamide, 4 -isubutyrate-3-methoxybenzaldehyde, 2,2,7,7-tetramethyltricyclo [6.2.1.01.6] undecan-5-one, 7-formyl-5isopropyl-2-methylbicyclo [2.2.2] oct-2-ene, 3-methyl -5-phenylpentanal, alpha-isomethyl-ionone, 10isopropyl-2,7-dimethyloxyspiro [4.5] 3,6-decadiene, tricyclo 2,2-dimethylpropanoate [5.2.1.026] dec-4-en-8-yl, pivalate of 2-phenylethyl and 2,4-dimethyl-4-phenyltetrahydrofuran as an insect repellent. Said invention of insect repellent perfume does not contemplate anthraquinone compounds extracted from aloe.
    Document ES2397512T3 proposes an insect repellent composition comprising the 1S, 9S, 5R, 6R5, 9-dimethyl-3oxabicyclo- [4.3.0] -nonan-2-one dihydronepetalactone stereoisomer, together with one or more adjuvants, a vehicle and an insect repellent compound that is not a dihydronepetalactone. This is another ES2542156A 1 refers to a cold natural Aloe Vera gel without stabilizers characterized by its method of obtaining according to the following phases; a) Selection and cutting of basal, hard, thick, fleshy and healthy leaves of adult plants over 4 years old, b) Washing in cold water by rubbing them with the hands until all impurities and dirt that could remain on the leaf are removed . c) Cut by knife or similar of each leaf by its base from side to side, removing between two and three centimeters of fleshyness and placing each leaf in an upright position for three hours in order to release the aloin. d) Second washing of the leaves to remove the rest of the aloin. e) Extraction of the gelatin that is inside each leaf, for this, it is first cut again from the part of the base two centimeters, thus removing the air-contaminated part and the brown / yellow aloin. f) Next, the tip and toothed sides of each leaf are cut, then the green shell that surrounds the blade is also removed with the knife and the jelly is extracted from the leaf. g) Crushing and casting the gelatin until obtaining the Aloe Vera gel characterized by its mucilaginous appearance, dense texture, sticky and transparent color. For this, use is made of a crushing or blender machine made of stainless steel and plastic material in its components, provided with a filter or strainer and taking into account that this process must be carried out without subjecting the product in any case to a temperature higher than 8 ° C. The procedure explained below differs from that described in this invention, while a gel is not sought but the product obtained is anthraquinones diluted in water, and its application is focused on repelling insects.

    Document ES0162397A1 refers to a procedure for obtaining means to combat insects, which are used emangogues for example sabina oil oil or essence of the saffron tree of paradise as powder or extract essence of cinnamon or bark of powdered cinnamon bark and yew alone or in any composition with gum arabic sugar and / or diatase. Said invention cites different compounds than those described in the proposed main invention.
    ES2197632T3 describes a process for preparing aloin from an aloe-containing substance, by extraction and purification by crystallization, which is extracted on the yellow sap of aloe or its hardened residue, in the presence of an aliphatic diol or triol. The procedure described in this patent is far from the one described below in addition to not being applied to repel insects as the proposed main invention does.
    Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does. Description of the invention
    The procedure for the extraction of anthraquinones from aloe to repel insects object of the present invention is carried out in the following stages:
    1) Aloe Vera cultivation, with the most favorable conditions possible such as warm weather, porous soil, sloping terrain and being exposed to the wind.
    2) Collection of the leaves, when the plants are mature (at least 18 months).
    image8
    image9
    image10
    4) Cut leaves perimeter, removing the skewers to promote the exit of the sap, where all the aloin is found.
    5) Placing the leaves in a container with water, to collect the sap (composed mostly of aloin) since it flows to the cut part as a defense mechanism that the leaf has. The sap collected is completely soluble in water. There should be at least 0.40 liters of water for each medium-sized aloe leaf and a minimum time is needed for the leaf to release the entire 24-hour sap.
    6) Extraction of the leaves once released from the sap and extraction of the clean gel that exists inside, separating the bark from the aloe with a knife or a presser on both sides. If you intend to take advantage of the gel, the previous phase will range between 24 and 48 hours so that the gel obtained is in perfect condition. (The gel thus obtained can be stored in a refrigerator for subsequent treatments according to the purpose to which it is intended (cosmetic, fertilizer, medicine, etc.).
    7) Placing the bark of the aloe leaves obtained in the same container previously used, in which the sap is diluted in water to obtain the rest of the anthraquinones (barbaloin, isobarbaloin, anthranol, anthracene, aloeic acid, cinnamic acid , ethereal oils, emodin, resistanoles, aloe emodin, chrysophanic acid and cinnamic acid esters) that exist in the bark. Also, the collected anthraquinones are totally soluble in water. It takes at least time for the barks to release all anthraquinones 24 hours; and between 24 and 48 hours to prevent the crusts from entering a process of deterioration and rot.
    8) Filtering, with a suitable sieve of the product obtained (anthraquinones diluted in water) to eliminate possible bark debris that may exist.
    For the product to be fully effective against mosquitoes (common and tiger) it must have a maximum of 65 liters of water per 100 Aloe Vera leaves of average size and quality. This proportion assumes that for every liter of product obtained a minimum amount of 9.3 grams of anthraquinones is diluted in water, and it can be applied sprayed, in atomizer or spray backpack, and by more conventional means such as spray or roll on.
