POLYPHENOLIC METABOLITES FROM Iris pseudacorus

摘要

Plants of the genus Iris contain several polyphenolic compounds possessing antioxidant, antitumor, and antimicrobial activity [1–3]. Leaves of I. pseudacorus L. biosynthesize isoflavonoids and flavonoids under the influence of copper-chlorideinduced stress [4, 5]. The goal of the present work was to isolate and characterize structurally polyphenolic metabolites from the aerial part of I. pseudacorus without the influence of stress factors. The plant was collected on Sakhalin Island in Doltinsky District in August 2012. The Eurasian species I. pseudacorus was introduced to Sakhalin Island and propagated along the shores of reservoirs in the southern part of the island. Herbarium specimen No. 103568 is preserved in the herbarium of the Laboratory of Chemotaxonomy, PIBOC, FEB, RAS.
