Abstract

A new iridoid glucoside, 2, named kickxioside, was isolated from Kickxia spuria. On the basis of spectral data, the structure of antirrhinoside esterified at position 6 by a menthiafolic acid was assigned to 2. The structure was also confirmed by alkaline hydrolysis of 2, which afforded antirrhinoside and menthiafolic acid.
