Abstract

Three new 3,4-seco-grayanane diterpenoids, neopierisoids D-F (2-4), and a new natural one, neopierisoid C (1), were isolated from the flowers of Pieris japonica. Their structures were elucidated on the basis of extensive spectroscopic analysis, including one and two dimensional (1- and 2D)-NMR, as well as high resolution-electron ionization (HR-EI)-MS.

摘要

从日本马醉木的花中分离出了三种新的3,4-裂贝壳杉烷二萜类化合物，新马醉木素D - F（2 - 4），以及一种新的天然产物，新马醉木素C（1）。它们的结构通过广泛的光谱分析得以阐明，包括一维和二维（1D和2D）核磁共振，以及高分辨率电子电离（HR - EI）质谱。
