Two new compounds from Helichrysum arenarium (L.)

Abstract

Two new compounds were isolated from the whole plant of Helichrysum arenarium (L.) Moench. By means of spectroscopic data (IR, UV, 1D and 2D NMR, HR-MS, ESI-MS, and NOESY) and chemical evidence, the structures were established as 6,7-dimethoxy-4-hydroxy-1-naphthoic acid (1) and (Z)-5-hydroxy-7-methoxy-4-[3-methyl-4-(O-β-d-xylopyranosyl)but-2-enyl]isobenzofuran-1(3H)-one (2).

Keywords:
