Abstract
Check gland secretions were collected from sexually mature male and female rats to identify the volatile compounds using gas chromatography linked mass spectroscopy with a modified head space technique. Twenty one volatile fractions including alkanes, aliphatic acids, esters and alcohols were found. Three compounds viz. 3-octen-1-ol (E) (I), cyclopentane undecanoic acid (II) and 2,4,6,8 tetramethyl-l-undecane (III) were present in very high concentrations in both male and female rats. In addition, the estrus female contained another compound, L-alanine, 1,1-dimethyl ethyl ester. On the basis of odour preference tests the compounds I, II and III were found to attract both male and female of the homotypic species. In contrast, the fourth compound present in the female attracts the opposite sex. The results suggest that the volatile fractions have unique function and the level of attraction varies from compound to compound.
