| Abstract: | Two new unusual xanthones, 5‐O‐β‐d ‐glucopyranosyl‐1,3,8‐trihydroxy‐5,6,7,8‐tetrahydroxanthone (1) and 1,3,5,8‐tetrahydroxy‐5,6,7,8‐tetrahydroxanthone (2), were isolated from Lomatogonium carinthiacum (Wulf) Reichb. Their structures were elucidated on the basis of spectroscopic methods including UV, IR, ESI‐MS, 1D NMR, and 2D NMR. Copyright © 2013 John Wiley & Sons, Ltd. |
