从桃金娘（Rhodomyrtus tomentosa）叶片中分离得到两个新的部分萜类化合物，即桃金娘酮A和B，它们具有一个前所未有的、由卡环烯共轭的氧杂螺[5.8]十四碳二烯骨架。通过大量的光谱分析、单晶X射线衍射、量子分子计算、化学转化以及全合成等手段，确定了它们具有独特NMR特征的结构。
Two novel meroterpenoids, rhodomentones A and B bearing an unprecedented caryophyllene-conjugated oxa-spiro[5.8] tetradecadiene skeleton, were isolated from the leaves of Rhodomyrtus tomentosa. Their structures with unique NMR characteristics were determined by extensive spectroscopic analysis, single-crystal X-ray diffraction, quantum molecular calculation, chemical transformation as well as total synthesis.
