Alkaloids of Thalictrum orientale

Alkaloids of Thalictrum orientale Chemistry of Natural Compounds, Vol. 37, No. 3, 2001 1 2 F. Z. Erdemgil, M. V. Telezhenetskaya, UDC 547.944/945 2 2 M. G. Levkovich, N. D. Abdullaev, 1 1 N. Kirimer, and K. H. C. Baser We have investigated the alkaloid composition of Thalictrum orientale Boiss. (Ranunculaceae) which had not been studied previously. The plant material subjected to this study was collected at flowering stage in May 1995 around Nigde: Ulukisla in Turkey. It is a tiny plant, which grows out of crevices on rocky slopes and has a narrow distribution [1]. Extraction of the dried underground parts was carried out following the method described earlier [2] and the extract was fractionated to yield ether-soluble non-phenolics (A), ether-soluble phenolics (B), chloroform soluble bases (C), and quaternary alkaloids (D). Ether-soluble non-phenolic bases (A) were separated on an Alumina column to isolate individual base 1.
