Abstract
"PROCESSOS PARA A EXTRAçãO DE CONCENTRADO DE éSTERES DE TRANS-XANTOFILA DE éSTER DE TRANS-LUTEìNA A PARTIR DE FLORES DE CALêNDULA E DE UM CONCENTRADO DE CAROTENóIDE A PARTIR DE UM MATERIAL DE PLANTA". Um processo para a extração de concentrados de ésteres de trans-xantofila, cujo processo compreende (a) contatar o material de planta contendo os ésteres de xantofila com um solvente selecionado dentre um álcool ou uma nitrila durante um tempo suficiente para extrair os compostos não xantofila do material de planta; (b) separar o álcool ou solvente nitrila e os compostos não xantofila dissolvidos no mesmo do material de planta restante; (c) contatar o material de planta restante com um solvente hidrocarboneto durante um tempo suficiente para extrair o éster de xantofila do material de planta. O processo resulta em um alto rendimento de produto de ésteres purificados."PROCESSES FOR THE EXTRACTION OF CONCENTRATE FROM TRANS-LUANINE ESTER TRANS-XANTOPHYL ESTERS FROM CALENDAR FLOWERS AND A CAROTENOID CONCENTRATE FROM PLANT MATERIAL". A process for extracting trans-xanthophyll ester concentrates, the process of which comprises (a) contacting the plant material containing the xanthophyll esters with a solvent selected from an alcohol or a nitrile for a time sufficient to extract non-xanthophyll compounds. of plant material; (b) separating the alcohol or nitrile solvent and non-xanthophyll compounds dissolved therein from the remaining plant material; (c) contacting the remaining plant material with a hydrocarbon solvent for a time sufficient to extract the xanthophyll ester from the plant material. The process results in a high yield of purified ester product.
