Abstract: | "The volatiles from pigeon's excrement were obtained with a simultaneous distillation and extraction (SDE) equipment. The chemical composition of the volatiles was examined by means of capillary gas chromatography and combined gas chromatography-mass spectrometry. Forty seven constitutents of the volatiles were identified by gas chromatography-mass spectrometry. Of these compounds, thirty nine were further identified by measuring their temperature-programmed retention indexes or retention times on OV-1 and PEG-20M columns and making comparison with those of the corresponding authentic samples. The total compounds identified make 57% of the total peak areas. The compound classes consist of alcohols (4), aldehydes (11), ketones(4), acids (8), esters (5), and phenols (2), amounting to 43.68% of the total peak areas. The ten compounds with highest contents are, hexadecanoic acid (9.03%), ethyl acetate (6.85%), ethanol (4.03%), 1-ethoxy-2-methylpropane (3.87%), acetic acid (3.23%), heptadecane-(8)-carbonic acid (3.20%), (Z,Z)-9,12-octadecadienoic acid (3.18%), nonanal (2.85%), 1,2-benzenedicarboxylic, dibutyl ester (2.65%), and acetaldehyde (2.32%). Pigeon's excrement has long been used as a Chinese traditional medicine for the therapeutic treatment of haemorrhoid. Some of the constituents identified in the work have been reported to have antibacterial activities" |
