Abstract

Studies on the chemical constituents of the aerial parts of Kalidium foliatum led to the isolation of three new olean‐12‐ene‐23,28‐dioic acids in their either partly or fully esterified forms (Me or glucosyl (Glc) esters), which were named kalidiumoside A (1), kalidiumin (2), and kalidiumoside B (3). Their structures were elucidated through spectral studies including 2D‐NMR experiments (HMQC, HMBC, COSY, NOESY) and J‐resolved spectra. Also isolated were the two known compounds dianic acid and dianoside F, which were identified through comparison of their spectroscopic data with those reported in the literature.
