Abstract From three of five investigated species of Griselinia a newiridoidglucoside, griselinoside, was isolated. It was found to be present also in foliage of Aralidium pinnatifidum and Toricellia angulata , accompanied in the former by aralidioside another novel iridoidglucoside. The structures and absolute configurations of the two iridoids were elucidated by NMR spectroscopy and chemical conversions
摘要 从五个研究的 Griselinia 物种中的三个中分离出一种新的环烯醚萜苷,griselinoside。发现它也存在于 Aralidium pinnatifidum 和 Toricellia angulata 的叶子中,在前者中伴随着另一新的环烯醚萜苷中的花生四烯甙。两种环烯醚萜的结构和绝对构型通过核磁共振光谱和化学转化来阐明。从 G. littoralis 和 T. angulata 中分别分离出葡萄糖苷木兰苷和丁香苷。给出了十三种环烯醚萜衍生物的 13 C NMR 谱。
