A novel derivative of myo-inositol was isolated from the needles of Taxus baccata and identified as p-coumaric acid ester. By means of its levorotatory optical activity and formation of a borate complex, the compound was designated tentatively as a 1l-4-p-coumaroyl-myo-inositol. Chemotaxonomic investigations have shown this ester to be present in needles of 14 out of 34 tested species of gymnosperms. When (14)CO(2) or (14)C-myo-inositol were fed to young needles of T. baccata, there was a rapid incorporation of label in the p-coumaroyl ester, and a pulse-chase experiment indicated a substantial turnover of this compound over a 4-month period.
从红豆杉的针叶中分离得到肌醇的一种新衍生物，并鉴定为对香豆酸酯。根据其左旋光活性和硼酸络合物的形成，该化合物被暂定命名为 1l-4-对香豆酰基肌醇。化学分类学研究表明，这种酯存在于 34 种测试过的裸子植物的针叶中。当 (14)CO(2) 或 (14)C-肌醇被喂给红豆杉的幼针叶时，标记迅速掺入对香豆酰酯中，脉冲追踪实验表明该化合物在 4 个月内有大量转化。
