采用有机溶剂萃取法，对五种不同科的法国蕨挥发性有机化合物（VOC）进行了GC-MS分析。共鉴定出55种由莽草酸、植物酸和萜类途径生物合成的VOC，包括单萜、倍半萜和类胡萝卜素类化合物。对铁线蕨的主要挥发性成分进行了研究。（蕨科）是（E）-2-癸烯醛，具有塑料或“臭虫”气味。采用气相色谱法测定了细叶芹（A. filix-femina（L.）Roth（Woodsiaceae）和毛蕨Blechnum spicant（L.）Roth（Blechnaceae）表现出相似性，具有少量的类异戊二烯和相同的主要挥发性化合物，即，2-苯乙醛（丁香和风信子的气味）和1-辛烯-3-醇（蘑菇样气味）。本文研究了毛蕨Dryopterisfilix-mas（L.）Schott（鳞毛蕨科）是（E）-橙花叔醇，具有木质或新鲜树皮的味道。聚酮化合物主要在这种蕨类植物中鉴定出来，为酰基青霉酸。Oreopteris limbosperma（Bellardi ex.所有。）以柠檬味著称的金叶蕨科植物J. Holub的VOC生物多样性最高。80%的挥发性物质是由萜类化合物途径产生的。主要挥发物为橙花叔醇、α-松油醇、β-香芹烯和其它少量单萜（如芳樟醇、蒎烯、柠檬烯和γ-松油烯-7-醛）。它也是类胡萝卜素类衍生物数量最多的蕨类植物，这些衍生物被大量鉴定。我们的研究结果是非常感兴趣的潜在的新的工业valorisation蕨类植物的基础上，其广泛的挥发物。
Five French ferns belonging to different families were investigated for volatile organic compounds (VOC) by GC-MS using organic solvent extraction. Fifty-five VOC biosynthesized from the shikimic, lipidic and terpenic pathways including monoterpenes, sesquiterpenes and carotenoid-type compounds were identified. The main volatile compound of Adiantum Capillus-Veneris L. (Pteridaceae) was (E)-2-decenal with a plastic or “stink bug” odor. The volatile profiles of Athyrium filix-femina (L.) Roth (Woodsiaceae) and Blechnum spicant (L.) Roth (Blechnaceae) showed similarities, with small amounts of isoprenoids and the same main volatile compounds, i.e., 2-phenylethanal (odor of lilac and hyacinth) and 1-octen-3-ol (mushroom-like odor). The main volatile compound of Dryopteris filix-mas (L.) Schott (Dryopteridaceae) was (E)-nerolidol with a woody or fresh bark note. Polyketides, as acylfilicinic acids, were mainly identified in this fern. Oreopteris limbosperma (Bellardi ex. All.) J. Holub (Thelypteridaceae), well-known for its lemon smell, contained the highest biodiversity of VOC. Eighty percent of the volatiles was issued from the terpenic pathway. The main volatiles were (E)-nerolidol, α-terpineol, β-caryophyllene and other minor monoterpenes (for example, linalool, pinenes, limonene, and γ-terpinen-7-al). It was also the fern with the highest number of carotenoid-type derivatives, which were identified in large amounts. Our results were of great interest underlying new industrial valorisation for ferns based on their broad spectrum of volatiles.
