| titleOfInvention | Method and the thin-layer chromatography detection method of vitamin E is extracted from useless white bole |
| abstract | The invention discloses a kind of method extracting vitamin E from fats and oils processing gives up white bole, take the useless white bole after using in grease processing technique, add the ethanol solution of 95%, ultrasonic extraction 3 times；Merge upper solution, centrifugal, solvent is evaporated off, adds n-hexane, reflux extraction, stratification, take upper strata n-hexane layer, n-hexane is evaporated off and i.e. obtains vitamin E.Present invention also offers the thin-layer chromatography scanning detection method of a kind of vitamin E: (1) thin-layer chromatography: by sample liquid, and vitamin E oil titer point is on same High Performance Thin silica gel plate, pre-equilibration 20 minutes, plate is put into expansion cylinder, ascending development, taking-up is dried, and again launches, taking-up is dried, and red fuming nitric acid (RFNA) develops the color；(2) thin layer scanning, detection is calculated the regression equation of the relation of vitamin E standard solution quality and integrating peak areas value, then calculates the mass concentration of vitamin E in sample liquid.There is the advantages such as simple, quick, accurate, reliable, stable. |
