4-oxo-4<i>H</i>-pyran-2.6-dicarboxylic acid (chelidonic acid, ChA) in the native state and in the complex with calcium [Ca(ChA)(H<sub>2</sub>O)<sub>3</sub>], named saucalchelin (CaChA), was isolated from the extract of <i>Saussurea controversa</i> leaves for the first time for the <i>Asteraceae</i> family. The structure of ChA was determined by NMR, MS and confirmed by X-ray analysis of its monomethyl ester, and CaChA was described by IR, ICP-MS, CHN analysis. The yield of ChA and CaChA was 45 m ...[more]
