Abstract

Six new cassane diterpenoids, named caesalls H-M (1-6), were isolated from the seed kernels of Caesalpinia bonduc. Their structures were elucidated on the basis of spectroscopic analysis, mainly NMR and MS. The absolute configurations of compounds 1 and 3 were determined by a single-crystal X-ray study using a mirror CuKα radiation and circular dichroism (CD) spectra, respectively. None of the compounds were cytotoxic against HepG-2, MCF-7 and MG-63 cells.

摘要

从决明子的种子仁中分离出六种新的决明烷二萜类化合物,命名为决明素H-M(1-6)。它们的结构通过光谱分析,主要是核磁共振(NMR)和质谱(MS)来阐明。化合物1和3的绝对构型分别通过使用镜像CuKα辐射的单晶X射线研究和圆二色性(CD)光谱确定。这些化合物对HepG-2、MCF-7和MG-63细胞均无细胞毒性。
