Two new xanthones, 1,6-dihydroxyisojacereubin-5-O-beta-D-glucoside (1) and 3,6,7-tri-hydroxy-1-methoxy-xanthone (2), were isolated from Hypericum japonicum. The structural elucidation of the isolated compounds were primarily based on HREIMS, EIMS, UV, IR, 1D-, and 2D-NMR analyses, including COSY, HMQC, HMBC, and NOESY correlations.
从地耳草中分离得到两个新的呫吨酮，1,6-二羟基异金丝桃素-5-O-β-D-葡萄糖苷（1）和3,6,7-三羟基-1-甲氧基呫吨酮（2）。分离得到化合物的结构解析主要基于高分辨电子轰击质谱（HREIMS）、电子轰击质谱（EIMS）、紫外光谱（UV）、红外光谱（IR）、一维和二维核磁共振（1D-和2D-NMR）分析，包括化学位移相关谱（COSY）、异核多量子相干谱（HMQC）、异核多键相关谱（HMBC）和核Overhauser效应谱（NOESY）相关。
