Table 2. Precision (repeatability and reproducibility) through the phospholipid analysis in soybean powder

Phospholipids	Repeatability1)		Reproducibility2)

Phosphatidylethanolamine (PE)	241.43±18.20	7.54	249.59±23.50	9.42
Phosphatidylcholine (PC)	582.35±23.55	4.04	595.27±30.86	5.18

Total phospholipids	922.19±37.96	4.12	940.96±55.85	5.94

Repeatability, refers to the results of independent determinations obtained by analyzing SP (soybean powder) samples four times on a same day.
Reproducibility, refers to the results of independent determinations obtained by analyzing SP (soybean powder) samples four times on a different day.
Relative SD (%) ＝ SD / mean × 100.
