Title (EN) PROCESS FOR ESSENTIAL OILS ENCAPSULATION INTO MESOPOROUS SILICA SYSTEMS AND FOR THEIR APPLICATION AS PLANT BIOSTIMULANTS
(FR) PROCÉDÉ D'ENCAPSULATION D'HUILES ESSENTIELLES DANS DES SYSTÈMES DE SILICE MÉSOPOREUSE ET DE LEUR APPLICATION COMME BIOSTIMULANTS DES PLANTES
Abstract:
(EN) The present invention refers to a process for encapsulation, into mesoporous silica based systems, of essential oils intendent to be used as (bio)products with agricultural applications, and to a process for using these resulted encapsulated essential oils as plant biostimulants, especially for the cultivated medicinal / nutraceutical plants treatments. Process for essential oils encapsulation into mesoporous silica systems, consist of the following steps: preparation of a solution of sodium silicate and distilled water, in a ratio of 0.7 parts of silicate to 88,62-89,6 parts of water, under stirring for 30 min, at 500 revolutions per minute and at 40°C temperature; bringing over the sodium silicate solution of a 9.7-10.68 parts of ethanol solution, that contains 7.1- 7.16 parts of ethanol, 1.88-1.86 parts oleic acid, 0.14-0.86 parts 3- aminopropyltriethoxysilane, 0.52-0.86 parts thyme, lavender, basil or cinnamon essential oils, the parts being expressed in mass units; keeping the mixture under stirring for another 4 hours, at 40°C, and transferring the 100 parts of homogeneous and opaque formed dispersion in tightly sealed ampoules. Process of using essential oils encapsulated in mesoporous silica systems for the biostimuiation of the cultivated nutraceutical plant, Passiflora incarnata L. and Momordica charantia L., in order to promote additional accumulation of bioactive compounds, involve the application of doses of 2-4 kg/ha of microcapsules dispersion, with 0,86% thyme oil, in two treatments, at the beginning and at the end of blooming.
(FR) La présente invention concerne un procédé d'encapsulation, dans des systèmes à base de silice mésoporeuse, d'huiles essentielles destinées à être utilisées comme produits (biologiques) ayant des applications agricoles, ainsi qu'un procédé d'utilisation de ces huiles essentielles encapsulées obtenues comme biostimulants des plantes, notamment pour des traitements de plantes cultivées médicinales/nutraceutiques. Le procédé d'encapsulation d'huiles essentielles dans des systèmes de silice mésoporeuse comprend les étapes suivantes : préparation d'une solution de silicate de sodium et d'eau distillée, dans un rapport de 0,7 partie de silicate pour 88,62 à 89,6 parties d'eau, sous agitation pendant 30 minutes à 500 tours par minute et à une température de 40 °C; ajout à la solution de silicate de sodium de 9,7 à 10,68 parties d'une solution d'éthanol qui contient 7,1 à 7,16 parties d'éthanol, 1,88 à 1,86 parties d'acide oléique, 0,14 à 0,86 parties de 3-aminopropyltriéthoxysilane, 0,52 à 0,86 parties d'huiles essentielles de thym, de lavande, de basilic ou de cannelle, les parties étant exprimées en unités de masse; maintien du mélange sous agitation pendant encore 4 heures à 40 °C, et transfert de 100 parts de la dispersion homogène et opaque formée dans des ampoules hermétiquement fermées. L'invention concerne un procédé d'utilisation d'huiles essentielles encapsulées dans des systèmes de silice mésoporeuse pour la biostimulation des plantes cultivées nutraceutiques Passiflora incarnata L. et Momordica charantia L., afin de favoriser l'accumulation supplémentaire de composés bioactifs, impliquant l'application de doses de 2 à 4 kg/ha de dispersion de microcapsules, comprenant 0,86 % d'huile de thym, en deux traitements, au début et à la fin de la floraison.
