Abstract: | A novel compound, irisbungin, which was isolated from the leaves of Iris bungei Maxim., was elucidated as 5,7,5′-trihydroxy-coumaronochromone by spectroscopic methods and literature data. Along with the new coumaronochromone, nine known compounds, ayamenin B, mangiferin, hispidulin, apigenin, 3-phenyllactic acid, syringic acid, vanillic acid, p-coumaric acid and 3′,5′-dimethoxy-4′-O-β-d-glucopyranosyl-cinnamic acid were also isolated. All of the compounds were first isolated from this species. The presence of irisbungin and mangiferin in I. bungei Maxim. has important systematic significance for this species and the Iris genus. |
