摘　　要：AIM: To study the chemical constituents of Lomatogonium carinthiacum(Wulfen) Rchb. METHOD: The CHCl3-soluble fraction was separated by chromatography and the structures of the new compounds were elucidated by spectral experiments. RESULTS: Two new xanthones, 1, 8-dihydroxy-4, 5-dimethoxy-6, 7-methylenedioxyxanthone(1), 1, 4, 8-trimethoxyxanthone-6-O-β-D-glucoronyl-(1→6)O-β-D-glucoside(2) were isolated from the whole plant of Lomatogonium carinthiacum. CONCLUSION: Compounds 1 and 2 are new natural products.AIM： To study the chemical constituents of Lomatogonium carinthiacum（Wulfen） Rchb.
