Gas chromatographic evaluation of the volatile constituents of lung, brain and liver tissues.

Volatile metabolites from rat liver, lung and brain tissues were compared using gas chromatography. Volatiles released from the homogenized tissues at 95-100 degrees C were collected on a poly phenyl ether solid adsorbent. The adsorbed volatiles were examined by high-resolution gas chromatography. Markedly differing overall volatile profiles were observed for the tissue types examined, and it appears that certain constituents may be characteristic of a particular tissue.
