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.
