Table 1. Linearity and limits of detection and quantification of the vitamin K analysis using enzymatic extraction coupled with HPLC-FLD

Analytes	Regression equation1)	Correlation coefficient (R2)	LOD2) (μg/100 g)	LOQ3) (μg/100 g)
Phylloquinone	y=508.25x-0.0837	0.9999	0.017	0.040
Menaquinone	y=511.58x-0.0927	0.9999	0.021	0.052

y and x of the regression equation for phylloquinone and menaquinone indicate peak area (mAU) of HPLC chromatograms and the concentration of corresponding analytes, respectively.
