摘要
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 31,5'-dimethoxy-4-O-beta-D-glucopyranosyl-dnnamic acid were also isolated. All of the compounds were first isolated from this species. The presence of irisbungin and mangiferin in L bungei Maxim. has important systematic significance for this species and the Iris genus.
