| Summary | This standard provides a high-performance liquid chromatography method for simultaneous determination of soybean phospholipids phosphatidylcholine uses, phosphatidylethanolamine, phosphatidylinositol content of the three components of the method. This standard applies to oil soy lecithin, butter oil soybean phospholipids phosphatidylcholine, phosphatidylethanolamine, determination of phosphatidylinositol. This standard does not apply to the determination of soybean and soybean lysophosphatidylcholine lysophosphatidylethanolamine for. This standard phosphatidylcholine detection limit is 1. 21 �� 10-2 mg/mL, phosphatidylethanolamine detection limit is 4. 66 �� 10-2 mg/mL, phosphatidylinositol detection limit of 7. 36 �� 10 -3 mg/mL. |

Soybean phospholipid phosphatidylcholine,
Determination of phosphatidylethanolamine, phosphatidylinositol
1 Scope
This standard specifies a High Performance Liquid Chromatography soya lecithin phosphatidylcholine, phosphatidylethanolamine, phosphatidylcholine muscle use
The alcohol content of the three components of the method.
This standard applies to oil soy lecithin, de-phosphatidylcholine, phosphatidylethanolamine, determination of soybean oil phospholipid phosphatidylinositol. this
It does not apply Determination of soybean lysophosphatidylcholine and soy lysophosphatidylethanolamine used.
This standard phosphatidylcholine detection limit of 1.21 × 10-2mg/mL, phosphatidylethanolamine detection limit of 4.66 × 10-2mg/mL,
Phosphatidylinositol detection limit of 7.36 × 10-3mg/mL.
Principle 2
Multiple flow eluted with an equal distribution of the two phases in the column phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol component in solid
Phasing different residence time to achieve the purpose of separation. UV detector effluent line detection component, compared with standard series quantitation.
3 Reagents
3.1 hexane. chromatographically pure.
3.2 Isopropanol. chromatography.
3.3 Water. chromatography.
3.4 acetic acid. Chromatographic pure.
3.5 1% acetic acid solution. 1mL glacial acetic acid by chromatography water volume to 100mL.
3.6 phosphatidylcholine. standard substance, the purity of ≥99%.
3.7 phosphatidylethanolamine. standard material, the purity of ≥99%.
3.8 Phosphatidylinositol. standard material, the purity of ≥98%.
3.9 Mobile phase. Vp (n-hexane) + Vp (isopropanol) + Vp (1% acetic acid solution) = 8 + 8 + 1.
NOTE. As used phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol standard sources should be consistent with the measured sample, when the sample is measured as soybean lecithin,
The three standards should be derived from soybeans.
