Aromatic glycinonitriles and methylamines as pre-column fluorescence derivatization reagents for catecholamines
Hitoshi Nohta,Tomoyuki Yukizawa,Yosuke Ohkura,Makoto Yoshimura,Junichi Ishida,Masatoshi Yamaguchi +5 more
TL;DR: In this article, the reactivity of some catecholamines with aromatic glycinonitriles (AGN) and aromatic methylamines (AMA) was investigated in detail, to find pre-column fluorescence derivatization reagents for catecholine derivatives.

Liquid chromatographic determination of ornithine and lysine based on intramolecular excimer-forming fluorescence derivatization.
Hideyuki Yoshida,Yukitaka Nakano,Katsumi Koiso,Hitoshi Nohta,Junichi Ishida,Masatoshi Yamaguchi +5 more
TL;DR: This highly sensitive and selective fluorometric determination method had enough selectivity and sensitivity for the determination of ornithine and lysine in normal human urine.

Simultaneous determination of norepinephrine, serotonin, and 5-hydroxyindole-3-acetic acid in microdialysis samples from rat brain by microbore column liquid chromatography with fluorescence detection following derivatization with benzylamine.
TL;DR: It is concluded that the new fluorescence derivatization method in combination with microbore column liquid chromatography allows the simultaneous determination of NE, 5HT, and 5HIAA in the microdialysis samples at higher sensitivity, providing easier maintenance in routine use than that achieved by high-performance liquid chromatographic methods with electrochemical detection.

Highly selective and sensitive determination of tricyclic antidepressants in human plasma using high-performance liquid chromatography with post-column tris(2,2′-bipyridyl) ruthenium(III) chemiluminescence detection
Hideyuki Yoshida,Keiko Hidaka,Junichi Ishida,Ken-ichiro Yoshikuni,Hitoshi Nohta,Masatoshi Yamaguchi +5 more
TL;DR: In this paper, a simple, selective and sensitive determination method of tricyclic antidepressants was developed using high-performance liquid chromatography (HPLC) with chemiluminescence detection.

Chemiluminescent properties of some luminol related compounds (II)
TL;DR: In this paper, the chemiluminescent properties of three new luminol related compounds, viz. 6-isothiocyanatobenzo[g]phthalazine-1,4(2H,3H)-dione (IPO), 3-propyl-7,8-dihydropyridazino[4,5-g]quinoxaline-2,6,9(1H)-trione (PDIQ), and 3-benzyl -7, 8-D-hexyl-quadrithm
