Abstract

Thirteen compounds have been identified using gas chromatography mass spectrometry in the venom of the Sydney funnel-web spider, Atrax robustus. The compounds were identified as their trimethylsilyl or pentafluoropropionate derivatives and were citric acid, lactic acid, phosphoric acid, glycerol, urea, glucose, gamma-aminobutyric acid, glycine, spermidine, spermine, tyramine and octopamine. Female venom contained trace quantities of 5-methyoxytryptamine which was not detected in male venom. Quantitative determination of tyramine and octopamine was achieved using chemical ionization (CH4) gas chromatography mass spectrometry and deuterated internal standards.

摘要

利用气相色谱 - 质谱联用技术，在悉尼漏斗网蜘蛛（Atrax robustus）的毒液中鉴定出了13种化合物。这些化合物被鉴定为它们的三甲基硅烷基或五氟丙酸酯衍生物，分别是柠檬酸、乳酸、磷酸、甘油、尿素、葡萄糖、γ-氨基丁酸、甘氨酸、亚精胺、精胺、酪胺和章鱼胺。雌蛛毒液中含有痕量的5-甲氧基色胺，而雄蛛毒液中未检测到。酪胺和章鱼胺的定量测定是使用化学电离（CH4）气相色谱 - 质谱联用技术和氘代内标物来完成的。
