Abstract Low molecular weight venom constituents of the spider Scodra griseipes have been derivatized using bis(trimethylsilyl)‐trifluoracetamide and pentafluoropropionic anhydride. Examinatio of these derivatives by coupled gas chromatogrtaphy/mass spectrometry using electron ionization or ammonia‐ or isobutane‐chemical ionization allows their structural identification. Comparisons have also made with retention time and mass spectra of the pure compounds. Four acids: phosphoric, lactic, citric, Y‐aminobutyric (neurotransmitter0 and four basic biogenic amines: putrescine, cadaverine, spermidine and spermine have been found.
