Abstract The miscibility behaviour of polybenzylmethacrylate (PBMA) blends with polyethylene oxide (PEO) at different compositions has been studied by inverse gas chromatography (IGC). The adequacy of two molecule probes...

A sensitive and specific method based on liquid chromatography was developed and validated for the determination of phenytoin in human plasma using phenobarbital as internal standard. The drugs were extracted from plasma...

A High-Performance Liquid Chromatography method was developed for quantification of benzalkonium chloride (BAC) and separation of three major homologues, in nasal preparations. Chromatography separation was carried out o...

This paper describes a rapid (2.0 min) and sensitive (LLOQ 5 ng/mL) analytical method for the quantitation of hydrochlorothiazide (HCTZ) in human plasma. The method is based on High-performance Liquid chromatography-tand...

A new HPLC-DAD method has been developed and validated for the simultaneous analysis of five flavonoids (rutin, quercitrin, quercetin, kaempferol, and isorahamnetin) in rat plasma. Sample pretreatment consisted of a liqu...

Se desarrolló y validó un método rápido y simple por HPLC para la determinación de carbamacepina en plasma humano. Las condiciones cromatográficas fueron: columna C-18, fase móvil acetonitrilo:metanol:acetato de a...

A simple, rapid, sensitive and selective method of high-performance liquid chromatography with fluorescence detection was developed for determination of puerarin in rat plasma. Chromatography was carried out on a reverse...

Apesar da extensa utilização dos fitoterápicos, a qualidade destes medicamentos muitas vezes é deficiente e questionável. A tintura de Calendula officinalis L. tem um vasto emprego na obtenção de formulações fit...

O tomate é a principal fonte de licopeno que é um carotenóide com alta atividade antioxidante, podendo assim ser utilizado topicamente na forma de um fitocosmético no combate ao envelhecimento cutâneo. O objetivo de...
