Abstract

Four new mexicanolides with a Delta(14,15) double bond, named xylogranatins A and D (1-4), were isolated from the fruit of a Chinese mangrove Xylocarpus granatum, together with two known 8,9,30-phragmalin ortho esters, xyloccensins P and Q. Their structures were elucidated on the basis of spectroscopic data, especially 2D NMR techniques including HSQC, HMBC and NOESY.

摘要

从中国红树植物木果楝（Xylocarpus granatum）的果实中分离出四种具有Δ(14,15)双键的新墨西哥内酯，命名为木果楝素A和D（1 - 4），以及两种已知的8,9,30 - 贝壳杉烷原酸酯，木果楝辛P和Q。它们的结构通过光谱数据，特别是包括HSQC、HMBC和NOESY在内的二维核磁共振技术得以阐明。
