Abstract

A series of phenylphenalenone type compounds, known to play a role as phytoalexins in plants of the Musaceae family, have been identified for the first time in the leaf fibers of abaca (Musa textilis). Among the phenylphenalenone type compounds identified, the structure of a novel compound, (1R)-2,3-dihydro-4,9-dihydroxy-8-methoxy-1-phenylphenalene, has also been described in abaca fibers. Its structure was elucidated by analysis of one- and two-dimensional NMR (correlation spectroscopy, heteronuclear single quantum correlation, and heteronuclear multiple bond correlation) spectroscopic data.

摘要

在麻蕉（Musa textilis）的叶纤维中首次鉴定出一系列苯并菲酮类化合物，已知这些化合物在芭蕉科植物中作为植保素发挥作用。在所鉴定出的苯并菲酮类化合物中，还描述了一种新化合物（1R）-2,3-二氢-4,9-二羟基-8-甲氧基-1-苯基苯并菲的结构，该结构通过一维和二维核磁共振（相关光谱、异核单量子相关和异核多键相关）光谱数据分析得以阐明。
