Abstract

Two new euglobals, R1 (1) and R2 (2), together with eight known euglobals (3-10) were isolated from the leaves of Eucalyptus robusta. Their structures were established by means of spectroscopic analysis and single-crystal X-ray diffraction. Euglobal R1 (1) represents a new skeleton of formyl-isovaleryl phloroglucinol-coupled β-phellandrene.

摘要

从大叶桉树叶中分离出两个新的优球蛋白，即R1（1）和R2（2），以及八个已知的优球蛋白（3 - 10）。通过光谱分析和单晶X射线衍射确定了它们的结构。优球蛋白R1（1）代表一种甲酰基 - 异戊酰基间苯三酚偶联β-水芹烯的新骨架。
