Abstract

The structural characterization of two new abietanes and a new spiro-fused tricyclic diterpene isolated from the roots of Hyptis martiusii is described. The first member of a new class of rearranged abietane diterpenoids designated martiusane was characterized by the use of 1D NMR and several 2D shift correlated NMR pulse sequences (1H,1H-COSY, HMQC, HMBC and NOESY). Unambiguous 1H and 13C chemical shift assignments for all compounds are reported.

摘要

描述了从马蒂乌斯香科叶草根部分离得到的两种新枞烷型二萜和一种新的螺稠合三环二萜的结构表征。通过使用一维核磁共振（1D NMR）和几种二维位移相关核磁共振脉冲序列（1H,1H-COSY、HMQC、HMBC和NOESY）对一类新的重排枞烷型二萜（命名为马蒂乌斯烷）的首个成员进行了表征。报告了所有化合物明确的1H和13C化学位移归属。
