3 Principle
The sample was dissolved in isopropanol and separated by high performance liquid chromatography. The oryzanol content was determined by ultraviolet detector at a wavelength of 326 nm.
Quantity, external standard method quantitative.
4 reagents
4.1 Isopropanol. chromatographically pure.
4.2 Ethanol. chromatographically pure.
4.3 Oryzanol standard, purity ≥ 95%.
4.4 Oryzanol standard stock solution (2000μg/mL). Weigh 0.1g (accurate to 0.0001g) oryzanol standard (4.3)
Dissolve in a 50 mL brown volumetric flask with isopropanol (4.1) and bring up to volume. Shake well.
4.5 Oryzanol standard working solution. 0.5mL, 1mL, 2mL, 4mL, 6mL, 8mL, 10mL oryzanol standard reserve
The solution (4.4) was placed in a 100 mL volumetric flask and made up to volume with isopropanol (4.1) and shaken for use.
5 instruments
5.1 High Performance Liquid Chromatograph. equipped with a UV detector.
5.2 High performance liquid chromatography column. amino column (250mm × 4.6mm, 5μm).
5.3 Analytical balance. The division value is 0.0001g.
