- W2380459424 abstract "A method for simultaneous determination of retinol(vitamin A)、 vitamin D3、 tocopherol(vitamin E) and β-carotene in health food by HPLC was developed. The samples were saponified.The liposoluble vitamins were extracted by aether. The organic layer was dried by rotation evaporation,dissolved by mobile phase, and analyzed by HPLC.The linear ranges were 0.012～500 μg/mL,0.030～500 μg/mL,0.12～500 μg/mL,0.015～500 μg/mL and the detection limits were 0.24,0.60,2.40 and 0.30 μg/g for retinol,VD3,tocopherol and β-carotene respectively. The relative standard deviations(RSDs) for retinol,VD3,α-tocopherol and β-carotene were 1.9%、 3.4%、 4.6% and 2.9% respectively.The recoveries were 84.8%～111.2%,90.5%～113.9%,96.3%～119.0% and 91.4%～113.2% for retinol,VD3,tocopherol and β-carotene respectively.The seperation was completed within 20 min.The method was simple,rapid,sensitive and accurate.It can be used to simultaneously determine liposoluble vitamins in health food." @default.
