Analysis of the volatile compounds derived from cephalic glands of the fire beeTrigona (Oxytrigona) tataira by GC-MS was undertaken. The following compounds were readily identified: hydrocarbons:n-C11H24,n-C13H28,n-C14H30,n-C15H32,n-C17H36,n-C23H48,n-C15H30,n-C17H34,n-C21 H42, andn-C23H46; carboxylic acids: palmitic acid, linoleic acid, linolenic acid, stearic acid, and oleic acid; carboxylic esters: dodecyl acetate, tetradecyl acetate, hexadecyl acetate, octadecyl acetate, and dodecyl decanoate; monoketones: 5-hepten-2-one, 3-hepten-2-one, 2-heptanone, and 5-nonen-2-one. Two major components of the mixture were identified asE-hepten-2,5-dione andE-3-nonen-2,5-dione. Structures of these novel compounds were suggested by their GC-MS behavior and the GC-MS behavior of their dimethoximes and proved by comparison with authentic synthetic samples. Trace amounts of the corresponding Z isomers and the saturated analogs, heptan-2,5-dione and nonan-2,5-dione, were also found. The possible functions of these glandular constituents are discussed.
通过 GC-MS 对来自火蜂（Oxytrigona）tataira 头部腺的挥发性化合物进行了分析。以下化合物很容易被识别：碳氢化合物：n-C11H24、n-C13H28、n-C14H30、n-C15H32、n-C17H36、n-C23H48、n-C15H30、n-C17H34、n-C21 H42 和 n-C23H46；羧酸：棕榈酸、亚油酸、亚麻酸、硬脂酸和油酸；羧酸酯：十二酸乙酯、十四酸乙酯、十六酸乙酯、十八酸乙酯和十二酸癸酯；单酮：5-庚烯-2-酮、3-庚烯-2-酮、2-庚酮和 5-壬烯-2-酮。混合物中的两个主要成分被鉴定为 E-庚烯-2,5-二酮和 E-3-壬烯-2,5-二酮。这些新化合物的结构通过它们的 GC-MS 行为以及它们的二甲氧基肟的 GC-MS 行为来推测，并通过与纯合成样品进行比较来证明。还发现了痕量的相应 Z 异构体和饱和类似物，庚烷-2,5-二酮和壬烷-2,5-二酮。讨论了这些腺体成分的可能功能。
