                                    Citation: Nakano, H., Cantrell, C.L., Mamonov, L.K., Kustova, T.S., Fronczek, F.R., Ross, S.A. 2012. Chemical constituents from Echinops nanus and Echinops transiliensis. Biochemical Systematics and Ecology. 45:127-129.Interpretive Summary: Echinops, which belongs to the Asteraceae family, comprises about one hundred and twenty species. They are native to Eastern Europe, Central Asia, and south of the mountains of tropical Africa.  The roots of Echinops nanus and Echinops transiliensis were both collected at the flowering stage in Kazakhstan and were the subject of a phytochemical investigation. This is the first report on the presence of 5-(3-buten-1-ynyl)-2,2'-bithiophene, '-terthienyl, 1-methyl-4-quinolone, and hexacosyl-(E)-ferulate in E. nanus. Consequently, hexacosyl-(E)-ferulate might be chemotaxonomic marker in the genus Echinops.  This is the first report on the presence of echinothiophenegenol, stigmasterol and '-sitosterol in E. transiliensis.
