Iridoids in the Flora of Italy; Part 111. Kickxioside, A New Iridoid Glucoside from Kickxia spuria.
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.
