Abstract

Volatile components of seven Frullania species (Frullaniaceae) from New Caledonia, including five endemic species (F. bella, F. scalaris, F. mamnmillosa, F. cornita and F. falsicornuta), were analyzed by GC-MS in order to index these plants to known chemotypes. Constituents detected in these Frullania species were mainly sesquiterpenes, as well as the bibenzyl dihydrognetin, and the flavonoid naringinin-5,7,4'-trimethyl ether. These compositions allowed an indexation of Frullania species from New Caledonia to cyclocolorenone, sesquiterpene lactone and bibenzyl chemotypes. In addition, qualitative intraspecies variations of chemical composition were very important and made indexation to known chemotypes very tricky. Moreover, two of the endemic liverworts did not possess any biomarker that linked to a known chemotype.

摘要

对来自新喀里多尼亚的七种耳叶苔属植物（耳叶苔科）的挥发性成分进行了气相色谱-质谱分析，其中包括五个特有物种（美丽耳叶苔、梯叶耳叶苔、乳突耳叶苔、角耳叶苔和假角耳叶苔），以便将这些植物归类到已知的化学类型。在这些耳叶苔属植物中检测到的成分主要是倍半萜类化合物，以及联苄二氢克奈亭和黄酮类化合物柚皮素-5,7,4'-三甲醚。这些成分使得能够将新喀里多尼亚的耳叶苔属植物归类到环环色烯酮、倍半萜内酯和联苄化学类型。此外，化学成分的种内定性变异非常重要，这使得将其归类到已知化学类型变得非常棘手。此外，两种特有地钱属植物没有任何与已知化学类型相关的生物标志物。
