The plant Korolkowia sewertzovii Rgl., growing in Katrantau, Kirghiz SSR, was first studied. From its epigeal part collected in the flowering stage, 1.68% of total alkaloids were isolated by chloroform extraction, and 1.55% from the hypogeal part. Korseveriline (I) and sevkorine (II, C35H57NO7, mp 236-238°C, [α]D-41.1°) were obtained by column chromatography. Hydrolysis of sevkorine with 10% hydrochloric acid in ethanol yielded D-glucose and bases including sevkoridinine (V, C20H37NO2, mp 241-243°C, [α]D-43.2°), the main alkaloid. Structural analysis using IR, mass spectrum, and NMR showed sevkorine is 3β-O-D-glucopyranosylsevkoridinine (II). For Reseda luteola (USSR, uninvestigated for alkaloids), 17 kg of comminuted raw material was extracted with 1% sulfuric acid, passed through KU-1/KU-2 cation-exchange resins, desorbed with 1% ethanolic ammonia, and solvent-extracted to obtain 55.64 g total alkaloids. Two new bases, resedine (5.5 g) and resedinine (3.5 g), were isolated by silica gel column chromatography of combined ether-soluble alkaloids.
