| Abstract: | Summary The volatile constituents of wolf urine were examined via capillary gas chromatography and compared among male, female, and castrate male. Several compounds including methyl isopentyl sulfide, 3,5-dimethyl-2-octanone, and acetophenone were clearly associated with the gender of the animal and many displayed a seasonal dependence. In addition, 2 long-chain aldehydes isolated from urine samples by an HPLC procedure also correlated with the endocrine status of the animal.This work was partially funded by the US Fish and Wildlife Service.We thank Dr Sharon L. Smith of IBM Instruments, Danbury, Connecticut, for recording spectra of some wolf urinary constitutents on an IBM Fourier-transform IR spectrometer.No such compounds were observed in any other animal species during our previous work with several mammals. |
