摘要:
The present invention describes a method for obtaining enriched fractions of active ingredients from the genus Artemisia, enriched fractions obtained using said method and a bioactive composition including an enriched fraction from Artemisia. The method uses extraction with supercritical fluid in which the difference is sequential extraction in conjunction with a novel combination of specific conditions and steps, providing a novel advantageous effect to obtain enriched fractions of active ingredients with different chemical compositions for said application. The enriched fractions obtained of active ingredients from the genus Artemisia and/or the bioactive compositions thereof including an enriched fraction from Artemisia are mainly used in the pharmaceutical and cosmetic fields.La présente invention concerne un procédé d'obtention de fractions enrichies de substances actives à partir du genre Artemisia, des fractions enrichies obtenues au moyen dudit procédé et une composition bioactive comprenant une fraction enrichie à partir d'Artemisia. Le procédé utilise l'extraction avec fluide supercritique, le différentiel consistant en l'extraction de manière séquentielle, en association inédite de conditions et d'étapes spécifiques avec un effet avantageux encore jamais observé, d'où l'obtention de fractions enrichies de substances actives présentant différentes compositions chimiques pour une application donnée. Les fractions enrichies de substances actives du genre Artemisia et/ou lesdites compositions bioactives comprenant une fraction enrichie à partir d'Artemisia obtenues trouvent une application principalement dans les domaines pharmaceutique et cosmétique.A presente invenção descreve um processo para obtenção de frações enriquecidas de ativos a partir do gênero Artemísia, frações enriquecidas obtidas pelo dito processo e composição bioativa compreendendo fração enriquecida a partir de Artemísia.
