Characterization of glaucophyte naphtoquinone content. Identification of monohydroxylphylloquinone in Chlamydomonas reinhardtii and Cyanophora paradoxa by ultra-performance liquid-chromatography (UPLC, A,B) (left panel: (A) Chlamydomonas reinhardtii and (B) Cyanophora paradoxa extracts) followed (C and D) by mass spectrometry (MS, C,D). monohydroxylphylloquinone whose determined m/z values are 467.35 and 489.33 for the non-adduct form and Na+ adduct form, respectively, was detected as a single peak at ~7.6 min of the chromatogram (selected monitoring mode, m/z = 466.5–467.5).
