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-beta-D-xylopyranosyl)but-2-enyl]isobenzofuran-1(3H)-one (2).

摘要

从沙地一枝黄花（Helichrysum arenarium (L.) Moench.）全草中分离出两种新化合物。通过光谱数据（红外光谱、紫外光谱、一维和二维核磁共振、高分辨质谱、电喷雾电离质谱以及核欧沃豪斯效应谱）和化学证据，确定其结构分别为6,7-二甲氧基-4-羟基-1-萘甲酸（1）和（Z）-5-羟基-7-甲氧基-4-[3-甲基-4-(O-β-D-吡喃木糖基)丁-2-烯基]异苯并呋喃-1(3H)-酮（2）。
