“…Protein precipitation (PP), liquid-liquid extraction (LLE), and solid-phase extraction (SPE) are the three most common techniques used for vitamin K purification process in biological matrix to achieve efficient analyte recovery by reducing ion suppression and enhancement of analyte signal. Other approaches such as performing derivatization reactions (25)(26)(27)(28), emulsification mircroextraction (29), and sonication (30) have also been reported in sample preparations. PP is a rapid, generic and relative inexpensive sample preparation method.…”

“…Stripped matrices approach has also been taken in important consideration for vitamin K quantitation (54,65). Liu & coworkers used UV light to prepare stripped plasma matrix for menadione quantitation in human plasma through LC-MS approach (27). Klapkova et al also used UV light stripped method for determination of vitamin K and its analogues in postmenopausal women's serum by HPLC-FD detection (9).…”

“…Both contain a 2-methyl-1,4-naphthoquinone ring in their structure and differ as regard the substituent at the 3-position, which is a phytyl chain for PK and a side chain with repeated isoprenoid units for MK. Whereas PK appears in nature as a single compound, MK comprises a series of vitamers containing from 3 to 14 isoprene units (MK-3 to MK-14). , PK and MK are the natural forms of vitamin K, whereas menadione (MD, vitamin K 3 ) is a synthetic derivative used as a pharmaceutical, although the cleavage of dietary PK to produce MD by intestinal bacteria has been described …”

“…Successful determination of MD based on LC-MS/MS can be performed by quantifying the levels of MK-4 generated in the enzymatic reaction of recombinant human UBIAD1 with deuterium-labeled geranylgeranyl pyrophosphate (GGPP). 2 Moreover, Liu et al 9 recently reported an LC-MS/MS method for determination of MD relying on derivatization with 3-mercaptopropionic acid via Michael addition. The above methods for determination of MD are effective but complicated, necessitating the development of a novel facile analytical procedure.…”
