摘 要: | 利用顶空取样、溶剂解吸附和气质联用技术分析了黄鼬(Mustela sibirica)肛腺分泌物的挥发性成分。鉴定出的六种化合物均为含硫的环状有机物:(1)2,2-二甲基硫代环丁烷;(2)顺或反2,4-二甲基硫代环丁烷;(3)反-2,3-二甲基硫代环丁烷;(4)2-乙基硫代环丁烷;(5)2-丙基硫代环丁烷;(6)3,3-二甲基-1,2-二硫代环戊烷。尽管黄鼬肛腺成分的组成和鼬鼠其它种存在很大的相似性,但是成分组成的种间差异很明显。另外,2-乙基硫代环丁烷仅存在于雌性黄鼬中。很多研究已经证明对鼠类有驱赶作用的2,2-二甲基硫代环丁烷和2-丙基硫代环丁烷在黄鼬肛腺分泌物同时存在,说明黄鼬肛腺分泌物对鼠类可能有很强的驱避作用。

VOLATILE COMPOUNDS IN THE ANAL SAC SECRETION OF THE SIBERIAN WEASEL (MUSTELA SIBIRICA) |
| |
Abstract: | The volatile constituents of the anal sac secretion of the Siberian weasel ( Mustela sibirica) were sampled using the headspace technique and solvent desorption and then examined by gas chromatography mass spectrometry. Six compounds detected were all sulfur containing: (1) 2,2 dimethylthietane; (2) Cis or trans 2,4 dimethylthietane; (3) Trans 2,3 dimethylthietane; (4) 2 ethylthietane; (5) 2 propylthietane; (6) 3,3 dimethyl 1,2 dithiacyclopentane. Although the chemical constituents of the anal sac secretion of siberian weasels had great similarity to those of other Mustela species, inter species differences between them and other Mustela species existed. Moreover, 2 ethylthietane was present only in females. These differences in the chemical composition of anal gland secretions make it possible to communicate information about species and sex. Many studies have documented that synthetic 2,2 dimethylthietane and 2 propylthietane were effective rodent repellents, and since both 2,2 dimethylthietane and 2 propylthietane occurred in the Siberian weasel, the anal sac secretions of Siberian weasels may be highly repellent to rodents. |
