Simultaneous determination of 1,4-naphtoquinone, lawsone, juglone and plumbagin by liquid chromatography with UV detection

Original language description

Naphthoquinones, compounds of natural origin, mostly appeared as chromatic pigments. They are deposited in cells vacuoles, where they are dissolved (in glycoside form). Naphthoquinones are very toxic, antimicrobial, antifungal, antiviral and antiparasitic effects were observed. The aim of our work was to optimize the high performance liquid chromatography coupled with diode array detector for the determination of naphtoquinones (1,4-naphtoquinone, lawsone; juglone and plumbagin). Detection limits (3 S/N) of naphtoquinones were -- lawson 65 ng.ml-1, 1,4-naftochinon 50 ng.ml-1, juglon 75 ng.ml-1 and plumbagin 39 ng.ml-1. The optimized method was consequently used for the determination of the mentioned naphtoquinones in plant sample (Dionaea muscipula).
