Title: A STUDY ON EXTRACTION OF LUTEIN FROM MARIGOLD AND ITS PURIFICATION
Abstract: The technology of fitting conditions(the solvent,saponified concentration and saponification time) for extracting lutein from marigold is studied.The optimal conditions are as follows:CH2Cl2-the extracting solvent,saponified solution-4% and saponification time-2 hours.After column chromatographic separation,re-crystallization treatment and supercritical fluid precipitation treatment,the purity of lutein is improved.
