利用同时蒸馏萃取法（ＳＤＥ）提取了有治疗恶疮、霍乱效果的牛粪挥发性成分。用毛细管ＧＣ－ＭＳ联用法分离并初步鉴定了５０种组分，占总峰面积的７０．９２％，进一步用程序升温保留指数和标准样品联合确证了其中的２４种化合物，占总峰面积的３４．６８％，与Ｓａｄｔｌｅｒ保留指数库文献数据对照又确证了另外８种化合物，占总峰面积的６．０９％。其中含量较高的组分是己醛（６．２０％），三硫化二甲基（５．４８％），二硫化二甲基（４．５５％），壬醛（４．３５％），二甲基四磺酸酐（３．９６％），辛醛（３．６１％），庚醛（３．２２％）。从化合物的种类来看，主要为：醛类（１４个），醇类（３个），酮类（１２个），酸类（２个），它们共占总峰面积的４４．５４％。
Volatile components of cow dung used in the treatment of noxious and cholera were extracted by simultaneous distillation extraction (SDE). Fifty components were identified and identified by capillary GC-MS, accounting for 70.92% of the total peak area. 24 compounds were further identified by the program of warming retention index and standard sample, accounting for the total peak area 34.68%. Compared with the literature data of Sadtler’s retention index database, another 8 compounds were confirmed, accounting for 6.09% of the total peak area. The higher content of these components was hexanal (6.20%), trisulfide (5.48%), dimethyl disulfide (4.55%), nonanal Dimethyltetrasulfonic anhydride (3.96%), octanal (3.61%), heptanal (3.22%). From the types of compounds, aldehydes (14), alcohols (3), ketones (12) and acids (2) are the main compounds, accounting for 44.54% of the total peak area.
