Abstract Two new ent-kaurane diterpene glycosides, ranunculosides A 1 and B 2, and a new benzophenone, ranunculone C 3, were isolated from the aerial part of Ranunculus muricatus Linn. The chemical structures of compounds 1–3 were established to be 2S-ent-kauran-2β-ol-15-en-14-O-β-d-glucopyranoside, 2S,4S-ent-kauran-2β,18-diol-15-en-14-O-β-d-glucopyranoside, and R-3-2-3,4-dihydroxybenzoyl-4,5-dihydroxy-phenyl-2-hydroxylpropanoic acid, respectively, by spectroscopic data and chemical methods. The absolute configuration of 1 was determined by the combinational application of RP-HPLC analysis and Mosher’s method. View Full-Text
