Abstract

Marine brown alga Dictyota dichotoma (Dictyotaceae) collected from Karachi coast of Arabian Sea yielded two new dolastane-diterpenoids named: dichototetraol (1) and dichotopentaol (3) along with 2 of the same skeleton as a new source. Their structures have been characterized with the aid of 2D-NMR spectroscopic techniques.

摘要

从阿拉伯海卡拉奇海岸采集的海洋褐藻二叉网地藻（网地藻科）产生了两种新的多拉斯坦二萜类化合物，分别命名为：二叉四醇（1）和二叉五醇（3），以及另外两种具有相同骨架的化合物作为新来源。它们的结构已借助二维核磁共振光谱技术进行了表征。
