Two new acetophenone derivatives were isolated from the roots of Euphorbia ebracteolata Hayata, their structures were elucidated as 2,4-dihydroxy-6-methoxyl-methylene-3-methyl-acetophenone (1) and 2-dihydroxy-6-methoxyl-methylene-3-methyl-acetophenone-4-O-beta-D-glucopyranoside (2) on the basis of chemical and spectroscopic methods including (1)D- and (2)D-NMR techniques, and their cytotoxic activities were investigated by using the MTT method.
从大飞扬草 Euphorbia ebracteolata Hayata 的根部分离得到两个新的苯乙酮衍生物，根据化学和光谱方法，包括（1）D 和（2）D-NMR 技术，确定它们的结构为 2,4-二羟基-6-甲氧基亚甲基-3-甲基苯乙酮（1）和 2-羟基-6-甲氧基亚甲基-3-甲基-4-O-β-D-吡喃葡萄糖基苯乙酮（2）。并通过 MTT 法研究了它们的细胞毒性活性。
