From the seeds of S. nodosa iridoid, phenolic acid and saccharide fractions were obtained by column chromatography. The following compounds were detected in the fractions by chromatographic methods: iridoids - harpagide, harpagoside, harpagide acetate; phenolic acids - ferulic, vanillic, p-coumaric, p-liydroxybenzoic, caffeic, protocatechuic; saccharides - glucose, fructose, saccharose, raffinose. An oil was isolated with yield amounting to 22%. The contents of fatty acids were determined by gas chromatography: palmitic acid - 8,32%, stearic acid - 1,5%, oleic acid - 13,24%, linoleic acid - 62,81% and linolenic acid - 13,79%.The presence of ß-sitosterol was detected in the oil. A high dietetic and therapeutic value of the oil was indicated, which is due to a considerable content of linoleic acid and to the presence of ß-sitosterol.
