Samples are digested in a buffered lipase solution. Vitamin K is extracted using isooctane and concentrated. Extracts are run on an HPLC with fluorescence detection. An internal standard is used to compensate for any extraction inefficiencies and matrix interferences.
The method measures Vitamin K1, K2 (MK-4), and K2 (MK-7). Please provide estimates, if available.
