Abstract

A new phenolic glycoside, 3'-keto rhododendrin and a new sesquilignan, alutaceuol, together with twelve known phenolic compounds, were isolated from the leaves of Rhododendron alutaceum. Their structures were elucidated by extensive spectroscopic data analysis and comparison with literature values. In addition, the detailed analysis of 2D NMR data led us to conclude that the chemical shifts of dihydrobuddlenol B need to be revised.

摘要

从变色杜鹃（Rhododendron alutaceum）的叶子中分离得到一个新的酚糖苷，3'-酮杜鹃素和一个新的倍半木脂素，阿卢特醇，以及十二个已知的酚类化合物。通过广泛的光谱数据分析和与文献值的比较，阐明了它们的结构。此外，对 2D NMR 数据的详细分析使我们得出结论，需要修正二氢对映贝壳杉烯醇 B 的化学位移。
