Two new ether-insoluble resin glycosides named woodrosins I and II were isolated from the stems of Ipomoea tuberosa L., and their structures were determined on the basis of chemical and spectral data. Contrary to anticipation, they had an intramolecular cyclic ester structure similar to that of ether-soluble resin glycosides (Mayer's jalapin) hitherto isolated. It is proposed to use the terms, "jalapin" and "convolvulin," not according to the solubility in ether (Mayer's classification), but according to the structure, i.e., intramolecular esters and others, respectively.
从紫茉莉的茎中分离出两种新的醚不溶性树脂糖苷，分别命名为木玫瑰素I和II，并根据化学和光谱数据确定了它们的结构。与预期相反，它们具有与迄今分离出的醚溶性树脂糖苷（迈耶的加拉平）类似的分子内环酯结构。建议根据结构而非醚中的溶解度（迈耶分类法）来使用“加拉平”和“旋花苷”这两个术语，即分别指分子内酯和其他结构。
