The incorporation of 13C labelled glucose into trichocolein, deoxytomentellin, trans-phytol and stigmasterol has been studied in axenic cultures of the liverwort Trichocolea tomentella. Quantitative 13C NMR spectroscopic analysis of the resulting labelling patterns showed that the isoprene units of the hemi- and monoterpenoid moieties and the diterpene phytol are derived from the methylerythritol phosphate pathway, whereas the isoprene units of stigmasterol are built up via the mevalonic acid pathway. These results indicate the involvement of both IPP biosynthetic pathways in different cellular compartments. A new, hydroperoxy geranyl phenyl ether derivative is also described.
在苔类植物绒毛地钱的无菌培养物中,研究了13C标记的葡萄糖掺入曲尾藓素、脱氧棉叶醇、反式植醇和豆甾醇的情况。对所得标记模式进行的定量13C核磁共振光谱分析表明,半萜和单萜部分以及二萜植醇的异戊二烯单元源自甲基赤藓糖醇磷酸途径,而豆甾醇的异戊二烯单元则通过甲羟戊酸途径形成。这些结果表明两种异戊烯基焦磷酸生物合成途径参与了不同的细胞区室。还描述了一种新的氢过氧化香叶基苯基醚衍生物。
