Abstract

Atricins A (1) and B (2), two new oleanane-type triterpenes have been isolated from the chloroform-soluble fractions of Perovskia atriplicifolia and their structures assigned from (1)H and (13)C-NMR spectra, Distortion Enhancement by Polarization Trasfer (DEPT) and by 2D-COSY, HMQC, Nuclear Overhauser Enhancement Spectroscopy (NOESY) and Hetronuclear mutiple-bond correlation (HMBC) experiments.

摘要

从灰毛叶益母草的氯仿可溶部分中分离出了两种新的齐墩果烷型三萜类化合物——穿心莲内酯A（1）和穿心莲内酯B（2），并通过¹H和¹³C核磁共振谱、极化转移畸变增强（DEPT）以及二维COSY、HMQC、核Overhauser增强光谱（NOESY）和异核多键相关（HMBC）实验确定了它们的结构。
