Low molecular weight venom constituents of the spider Scodra griseipes have been derivatized using bis(trimethylsilyl)-trifluoroacetamide and pentafluoropropionic anhydride. Examination of these derivatives by coupled gas chromatography/mass spectrometry using electron ionization or ammonia- or isobutane-chemical ionization allows their structural identification. Comparisons have also been made with retention time and mass spectra of the pure compounds. Four acids: phosphoric, lactic, citric, gamma-aminobutyric (neurotransmitter) and four basic biogenic amines: putrescine, cadaverine, spermidine and spermine have been found.
