Abstract

''PROCESSO DE OBTENçãO DE ARTEMISININA A PARTIR DE ARTEMISIA ANNUA L.'', compreendendo o emprego de um processo de extração clássica, juntamente com um processo de extração em série, de modo que as soluções obtidas destes dois processos sejam tratadas com carvão ativado por aproximadamente 1,5 horas a temperatura ambiente, e em seguida filtradas sobre terra diatomita; obtendo-se uma solução de coloração amarelo escuro, na qual foi adicionada uma porção de sílica precipitada; sendo que o solvente é destilado e o sólido obtido (Farofa) é colocado em um extrator adaptado com agitador mecânico; a eluição desta farofa com hexano e subseq³ente hexano/acetato de etila 15% permitiu obter artemisinina com 91% e pureza.
