Continuing a study of the alkaloid composition of Thalictrum sultanabadense Stapf, roots collected in the Hissar range were investigated. From the nonphenolic fraction of the chloroform extract, thalictine (I) was identified via UV, mass, PMR, and CD spectra (confirming its S,S configuration). The mother liquor yielded O-methylthalmine (II), which was confirmed by comparison with an authentic sample and is the first time isolated from plant raw material. Thus, six bases were isolated from Th. sultanabadense, with thalbadensine, thalictine, and O-methylthalmine belonging to the thalmine group of bisbenzylisoquinoline alkaloids. Additionally, continuing a study of Nitraria komarovii alkaloids, chromatographic separation of the pH 4 ethereal fraction from the epigeal part yielded a new alkaloid komaroine (I, C28H28N2). Mass, PMR, UV, and IR spectral analysis showed komaroine to be a β-carboline derivative with an N-propyl group, confirmed by the dehydrogenation reaction of nitrarine.
