Cyathophorella adiantum (Griff.) M. Fleisch. (Division-Bryophyta, Family-Daltoniaceae), an Eastern Himalayan moss was studied for the first time to identify the volatiles derived from cellular and membrane bound fatty acids. A high capacity sample enrichment probe (SEP) was used for extraction of headspace volatile (HSV) molecules followed by GC-MS analysis. Different short-chain oxylipins like alkenes, alkanes, saturated and unsaturated alcohols, saturated and unsaturated aldehydes, ketones were identified along with free and esterified fatty acids, cyclo compounds and some by-products of secondary metabolites. Fatty acid analysis of neutral lipids (NL) and phospholipids (PL) of this plant exhibits the predominance of C16 and C18 fatty acids. It also reveals some interesting information that might indicate the possible fatty acid precursors for volatile generation and their sources in this plant.
首次对喜马拉雅东部苔藓植物铁线蕨叶杯蒴藓（Cyathophorella adiantum (Griff.) M. Fleisch.，苔藓植物门，道尔顿藓科）进行研究，以鉴定细胞和膜结合脂肪酸衍生的挥发物。使用高容量样品浓缩探头（SEP）提取顶空挥发物（HSV）分子，随后进行气相色谱 - 质谱分析。鉴定出了不同的短链氧化脂质，如烯烃、烷烃、饱和和不饱和醇、饱和和不饱和醛、酮，以及游离和酯化脂肪酸、环状化合物和一些次生代谢产物的副产物。对该植物中性脂质（NL）和磷脂（PL）的脂肪酸分析显示，C16和C18脂肪酸占主导地位。它还揭示了一些有趣的信息，可能表明该植物中挥发物生成的可能脂肪酸前体及其来源。
