The underivatized acetone and hexane fractions from propolis samples (predominant flora Citrus spp. and Vernonia polyanthes) were analyzed by HT-HRGC (high temperature high resolution gas chromatography) and HT-HRGC coupled to mass spectrometry (HT-HRGC-MS). Several compounds, including flavonoid ag
Extraction with ethyl acetate followed by gas-liquid chromatography on the extract provides a useful analytical method for phenol oxidase studies where it is desired to monitor directly the concentrations of volatile phenolic and catecholic substrates. A packed column with 10% DC-710 on Chromosorb W
A new graphical method is proposed for estimating the retention mechanism in gas-liquid partition chromatographic (GLPC) systems in which adsorption phenomena occur. The proposed method enables the adsorption phenomena accompanying the bulk liquid solution to be investigated unequivocally from gas c
