摘要：
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.La présente invention concerne un procédé dencapsulation, dans des systèmes à base de silice mésoporeuse, dhuiles essentielles destinées à être utilisées comme produits (biologiques) ayant des applications agricoles, ainsi quun procédé dutilisation de ces huiles essentielles encapsulées obtenues comme biostimulants des plantes, notamment pour des traitements de plantes cultivées médicinales/nutraceutiques.
