Abstract
(EN)
The present invention relates to the field of natural product extraction, and in particular relates to an industrialized method for rapidly and efficiently extracting xanthophyll and quercetagetin. The main improvement of the method lies in that a mixed solution of n-hexane and acetone solution is used as an extracting agent to extract marigold flower particles, wherein the volume fraction of acetone in the acetone solution is 80%-100%. The mixed extracting agent of the present invention has very high selectivity with regard to xanthophyll and quercetagetin, and can be used for effectively extracting the two effective components, and subsequently, xanthophyll and high-purity quercetagetin products can be obtained through simple separation; and the industrialized method has a simple process, is low in production cost, and is conducive to industrialized production.

La présente invention se rapporte au domaine de l'extraction de produits naturels, et concerne en particulier un procédé industrialisé d'extraction rapide et efficace de xanthophylle et de quercétagétine. L'amélioration principale du procédé réside dans le fait qu'une solution mixte de n-hexane et une solution d'acétone sont utilisées en tant qu'agent d'extraction pour extraire des particules de fleur de tagète, la fraction volumique d'acétone dans la solution d'acétone étant de 80 % à 100 %. L'agent d'extraction mixte selon la présente invention a une sélectivité très élevée vis-à-vis de la xanthophylle et de la quercétagétine, et peut être utilisé pour extraire de manière efficace les deux composants actifs, puis, des produits de xanthophylle et de quercétagétine de haute pureté peuvent être obtenus par simple séparation; le procédé industrialisé a un processus simple, un faible coût de production et mène à une production industrialisée.
