GC-MS analysis of fatty acids of Irvingia gabonensis seed fat was written by Okore, V. C.;Udeala, O. K.. And the article was included in Nigerian Journal of Natural Products and Medicine in 1997.Quality Control of 15-Bromopentadecanoic acid This article mentions the following:
Dika fat is the name given to the waxy material obtained from the seeds of Irvingia gabonensis (Fam. Irvingiaceae). The fat has been a subject of research in recent years, and it has been evaluated as a component of different drug delivery systems . Despite the impressive properties of this wax as have been established in the earlier studies, information on its chem. composition is rather scanty. Chem. characterization of the wax was done by GC-MS technique. The dika fat was obtained by solvent extraction, using the method described by Udeala et al (1980). A Fisons Trio 200 Quadrupole GC-MS instrument fitted with a 30m 鑴?0.32mm (i.d.) OV-1 capillary column, was used for the anal. The column temperature was programmed to rise from 100鎺矯 to 280鎺矯 at the rate of 5鎺?min. The carrier gas was helium flowing at the rate of 1.5ml/min. Ionization voltage of 70eV was applied. The solvent for dika fat was n-hexane. The identity of the components of dika fat was confirmed by a combination of computer-aided identification, the eight peak index of mas spectra as well as co-chromatog. The gas chromatogram of dika fat reveals seven peaks representing major components and about the same number of peaks for the minor components. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Quality Control of 15-Bromopentadecanoic acid).
15-Bromopentadecanoic acid (cas: 56523-59-2) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
