MAMMALIAN EXOCRINE SECRETIONS .10. CONSTITUENTS OF PREORBITAL SECRETION OF GRYSBOK, RAPHICENCS MELANOTIS

Using electron impact and chemical ionization mass spectrometry with m ethane and nitric oxide as reactant gases in conjunction with mass spe ctral analysis of the dimethyl disulfide derivatives of unsaturated co nstituents, 51 compounds have been identified in addition to the compo unds previously found in the preorbital secretion of the grysbok Raphi cerus melanotis. The compounds identified are saturated, monounsaturat ed, and diunsaturated alcohols and formates, saturated and monounsatur ated aldehydes, saturated carboxylic acids, gamma- and delta-lactones, alkyl methyl sulfides, and beta-hydroxyalkyl acetates. All of these c ompounds have unbranched structures. The constituent previously incorr ectly identified as (Z)-5-tetradecen-1-ol, was found to consist of the coeluting (Z)-7- and (Z)-8-tetradecenols.
