Abstract Capillary gas chromatography is evaluated for multicomponent drug analysis. A 0.32 mm id × 30 m fused silica column and a 0.75 mm id × 30 m borosilicate glass column (both with OV-1 bonded phase) are investigated. Retention times (relative to caffeine) are presented for 39 drug components representing a variety of chemical classes and pharmacological activities. Reproducibility data are presented for both isothermal and programmed temperature runs on selected drug mixtures. Recovery data are provided for 2 multicomponent drug mixtures prepared to approximate over-the-counter antihistaminic and antitussive preparations.

The essential oils in leaves of Eugenia uniflora L. and Eugenia involucrata- Myrtaceae from Rio Grande do Sul - Brazil, were analysed by gas chromatography with fused silica column, using H2 as carrier gas and gradient of temperature of 50°-20°C per 40°C/minute. For Eugenia uniflora L., the identified componentes were: limonene (9,84%), β-pinene (8,59%), camphene (2,73%), α-phellandrene (2,13%), myrcene (1,77%), α-pinene (1,43%), cyneol (9,13% and a great quantity of α-terpineol (39,20%), as major component. For Eugenia involucrata following compounds were detected: limonene (8,39%), β-pinene (4,63%), α-pinene (4,41%), camphene (2,19%), α-terpineol (2,16%), α-phellandrene (2%), myrcene (0,52%) and cyneol (6,38%).
