从蓝桉（Eucalyptus globulus Labill）叶片中分离得到两个新的酰基间苯三酚，分别鉴定为大果桉P（1）和Q（2）。使用常规的1D和2D NMR和质谱以及互补技术（UV和IR）进行结构解析。Macrocarpal Q是Macrocarpal E（3）的非对映异构体，其构型尚不精确。同时分离的macrocarpals E和Q允许确定这两种化合物的配置。还分离出二甲酰基间苯三酚（4）以及已知的化合物grandinol、macrocarpals D、I、L、N、O和am-1。(C)2014年欧洲植物化学学会。Elsevier B. V.出版，保留所有权利。
Two new acylphloroglucinols were isolated from the leaves of Eucalyptus globulus Labill and identified as macrocarpals P (1) and Q (2). Structural elucidations were carried out using conventional 1D and 2D NMR and mass spectrometry together with complementary techniques (UV and IR). Macrocarpal Q was a diastereoisomer of macrocarpal E (3), configuration of which was not precised. Simultaneous isolation of macrocarpals E and Q allowed to determine the configurations of both compounds. The diformylphloroglucinol (4) was also isolated as well as already known compounds grandinol, macrocarpals D, I, L, N, O and am-1. (C) 2014 Phytochemical Society of Europe.
