We describe the determination of the 4-O-methylated catecholamine metabolites 4-methoxy-3-hydroxyphenylacetic acid (iso-HVA), 4-methoxy-3-hydroxyphenylmandelic acid (iso-VMA) and 4-methoxy-3-hydroxyphenylethylene glycol (iso-MOPEG) in urine with use of mass fragmentography and deuterated internal standards. Normal values, expressed in terms of creatinine, are given as

Journal of neural transmission, 53(2-3), 101-108 (1982-01-01)
The injection of reserpine [2.5 mg/kg, intraperitoneally (i.p.)] increased brain concentration of tyrosine and of the major catecholamine metabolites, 3-methoxy-4-hydroxy-phenylethylene--glycol-sulfate (MHPG-SO4) in the rat. In reserpine-treated animals, tyrosine administration (200 mg/kg, i.p.) caused further increases in brain tyrosine, DOPAC, and

The levels of dopamine and its metabolites in the adenohypophysis of the normo- and hypertensive rats were determined. Dopamine was present as the free and sulfate-conjugated form in the adenohypophysis of the spontaneously hypertensive rat (SHR), Wistar Kyoto (WKY) and

The determination of urinary homovanillic, isohomovanillic and vanillylmandelic acids as their trifluoroacetylhexafluoroisopropyl ester derivatives by glass capillary gas-liquid chromatography has been studied. It was shown that even with high column efficiencies a single peak-single compound relationship could not be assumed

Polyphenols are often ingested alongside dietary fibres. They are both catabolised by, and may influence, the intestinal microbiota; yet, interactions between them and the impact on their resultant microbial products are poorly understood. Dietary fibres (inulin, pectin, psyllium, pyrodextrin, wheat
