RESUMO
The oral dosages formulations from Pothomorphe umbellata (Piperaceae) can only be therapeutically evaluated after establishing 4-nerolidylcatechol (4-NRC) pharmacokinetic profile in plasma. For that purpose, a unique analytical method validation using HPLC-UV detection was developed for analysis of rat plasma samples. The animals received 10 mg/kg b.w. of 4-NRC i.v.. Analytical conditions were set with C18 column, methanol acetonitrile water (622018) as mobile phase, and a flow rate of 1.6 mL/min. The assay was linear from 1.0 - 80.0 mcg/mL. The recovery procedure was performed by liquid-liquid extraction showing quantitative extraction (106.4 ± 8.7 por cento)...
