Steroid glycosides (SG) are nontoxic substances of plant origin with high physiological activity. Some SG have fungicide, antitumor, antiviral and other effect. In this work Cf-252 Plasma Desorption Mass Spectrometry has been used to investigate model mixtures of SG Bioside neotigogenine and Trioside neotigogenine extracted from Tomato seeds with amino acids. From the mass-spectra obtained it is seen that these SG have an ability to form noncovalently bound associates with some amino acids like [SG + amino acid + H]+ and [SG + amino acid + K}+.
