A new glucosidic iridoid from Isodon rubescens

Abstract One new glucosidic iridoid, 6- O -veratroylbarlerin, was isolated from the chloroform/methanol extract of Isodon rubescens (Hemsl.) H.Hara, Lamiaceae aerial parts, along with the known compounds apigenin and caffeic acid. The structure of the new compound was elucidated on the basis of 1D and 2D NMR experiments and ESI-MS technique.
