Abstract
Twenty three pregnant camel urine samples were analysed employing gas chromatographic mass spectrum (GCMS) under optimum
conditions. Thus sulphur, oxygen and nitrogen heterocyclic aromatic compounds belonging to thiophen, furan, pyridine and quinoline
were identified along with their aliphatic non-aromatic derivatives; with the sulphur containing compounds being most dominant.
Some aromatic hydrocarbons as well as their halogeno and alkyl derivatives were also identified including: benzene, naphthalene,
anthracene and phenanthrene. Organometallic compounds namely chlorotrimethyl tin (CH3)3 SnCl, triethylfluorotin(C2H5)3 SnF and
2-methyl seleno-selenophene C5Se2H6 were also identified along with the constituents of the very complex matrix. The number of
compounds identified exceeded 30 with molecular weight ranging between 220-490. However, none of the volatile fatty acids which
are usually used for pheromonal function were detected in any of the urine samples analysed. An explanation is put forward to account
for this finding.
