Many natural compounds have been identified and synthesized by the advancement of bryophytes phytochemistry studies. This work aimed to report the composition of Neckeropsis undulata (Hedw.) Reichardt moss volatiles, sampled in the Combú Island, Belém city, Pará state, Brazil. The volatile concentrate of N. undulata was obtained by a simultaneous distillation-extraction micro-system, analyzed by GC and GC-MS, and reported for the first time. Ten compounds were identified in the volatile concentrate, corresponding to 91.6% of the total, being 1-octen-3-ol (35.7%), α-muurolol (21.4%), naphthalene (11.3%), and n-hexanal (10.0 %) the main constituents. Most of the constituents of the N. undulata volatile concentrate have been previously identified in other mosses, and liverworts spread wide in the world. 1-Octen-3-ol, n-hexanal, 2-ethylhexanol, isoamyl propionate, and octan-3-one are already known metabolic products obtained from enzymatic oxidation of polyunsaturated fatty acids, belonging to the large family of minor oxygenated compounds known as oxylipins. The knowledge of the composition of volatiles from moss N. undulata could contribute to the Neckeraceae species’ chemotaxonomy.

来自新热带苔藓Neckeropsis undulata（Hedw。）Reichardt的挥发性浓缩物，存在于巴西亚马逊河中

通过苔藓植物植物化学研究的进展，已经鉴定并合成了许多天然化合物。这项工作的目的是报告在巴西帕拉州贝伦市的Combú岛上采样的耐寒苔藓挥发物的成分。通过同时蒸馏-萃取微系统获得了无花猪笼草的挥发性浓缩物，并通过GC和GC-MS进行了分析，并首次进行了报道。在挥发物浓缩物中鉴定出十种化合物，占总量的91.6％，分别是1-辛烯-3-醇（35.7％），α-莫洛洛尔（21.4％），萘（11.3％）和正己醛（10.0） ％）主要成分。先前已在其他苔藓中发现了扁桃猪笼草挥发性浓缩物的大多数成分，并且地艾草在世界范围内广泛传播。1-Octen-3-ol，n-hexanal，2-ethylhexanol，丙酸异戊酯和octan-3-one是从多不饱和脂肪酸的酶促氧化获得的已知代谢产物，属于不饱和含氧化合物的大家族，被称为羟脂。知道来自苔藓N. undulata挥发物成分的知识可能有助于颈科物种的化学分类。
