Separation of sulfur-containing fatty acids from garlic, Allium sativum, using serially coupled capillary columns with consecutive nonpolar, semipolar, and polar stationary phases

Dembitsky V. M., Abu-Lafi S., Hanuš L. O.

Acta Chromatographica

2007

No. 19

206-216

A GC–MS method with serially coupled capillary columns containing consecutive nonpolar, semipolar, and polar stationary phases has been used for determination of fatty acids in garlic (Allium sativum). Saturated (14:0, 15:0, 16:0, and 18:0), unsaturated (7-16:1, 7-18:1, 9-18:1, 9,12-18:2, 9,12,15-18:3), and unusual cyclic sulfur-containing fatty acids in garlic were identified by GC–MS.

Comparative study of volatile compounds in the fresh fruits of Mandragora autumnalis

Hanuš L. O., Dembitsky V. M., Moussaieff A.

Acta Chromatographica

2006

No. 17

151-160

Extracts of Mandragora autumnalis (mandrake) fruit have been analyzed by GC–MS. One-hundred and thirty-five compounds were identified in extracts obtained from the fruit after removal of the seeds – twentythree n-alkanes, one branched-chain alkane, two cyclohexanes, eight alkenes, two branched-chain alkenes, three alcohols, three aldehydes, six ketones, eight heterocyclic compounds, four thio compounds, six benzene hydrocarbons, three phenols, eighteen carboxylic acids, and forty-eight esters of carboxylic acids.
