The new caurene-type diterpenoid diglycoside puligiendioside was isolated from Pulicaria uliginosa. Its structure was established using PMR and 13C NMR spectral data and DEPT, HSQC, HMBC, and COSY experiments. The stereochemical features and absolute configuration of asymmetric centers were determined by an X-ray crystal structure analysis. Crystals of the compound contained three water molecules, one of which was disordered over two positions with total population 0.85. Puligiendioside had the structure ent-caur-16-en-15-O-β-xylosyl-19-α-ester-β-glucopyranosyl.
