摘要

Two new 2-(2-Phenylethyl) chromones were isolated from Bothriochloa ischaemum (Grami neae). They were characterized as 5-hydroxy-6-methoxy-2-[2-(2-hydroxyphenyl)-ethyl]-chro mone(1) and 5-hydroxy-2-[2-(2-hydroxyphenyl)-ethyl]-chromone(2) by means of spectroscopic analysis, especially 2D-NMR experiments.
