摘　　要：利用同时蒸馏萃取法（ＳＤＥ）提取了有治疗痔疮效果的鸽子粪中的挥发性成分。用毛细管ＧＣ／ＭＳ／ＤＳ联用法分离鉴定了４７种组分，占总峰面积的７１．５９％，再用保留指数和标样进一步确证了其中３９种化合物，占总峰面积的５７．１５％，其中含量较高的组分是十六碳酸（９．０３％）、乙酸乙酯（６．８５％）、乙醇（４．０３％）、１－乙氧基－２－甲基丙烷（３．８７％）。从化合物的种类看，主要为醇类（４个）、醛类（１１个）、酮类（４个）、酸类（８个）、酯类（５个）和酚类（２个），它们共占总峰面积的４３．６８％。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.
