Abstract

The present study was carried out to investigate the essential oil yield and chemical composition of essential oils from the fruits of Ferulago cassia Boiss. The fruits of F. cassia, a native plant of Turkish flora, were collected at the seed maturing stage from different localities and the essential oils were extracted by hydrodistillation. Chemical components of the oils were identified by GC and GC-MS. The oil yields on a dry weight basis ranged between 5.0 % to 7.8 %. The number of essential oil components was between 44 to 64 for different locations and a total of 78 compounds were identified. Major qualitative and quantitative variations of some compounds were determined for localities. The major components were chrysanthenyl acetate (13.54 % - 24.49 %), 2,3,6-trimethylbenzaldehyde (5.94 % - 25.52 %), L-limonene (4.69 % - 27.44 %), α-pinene (7.64 % - 12.43 %), β-myrcene (3.44 % - 10.38 %) and L-phellandrene (2.90 % - 9.75 %). Results showed that plants collected from different localities had different chemical compositions. Collection, selection and cultivation of different genotypes based on reported results could allow breeders to develop chemotypes for oil extraction and use.

摘要

进行本研究以研究来自Ferulago决明子果实的精油得率和化学成分。决明子的果实，是土耳其植物区系的本地植物，在种子成熟阶段从不同的地方收集，并通过加氢蒸馏提取精油。通过GC和GC-MS鉴定了油的化学成分。以干重计，油产率为5.0％至7.8％。不同位置的香精油成分数量在44至64之间，共鉴定出78种化合物。确定了某些化合物在位置上的主要定性和定量变化。主要成分是乙酸蒽蒽（13.54％-24.49％），2,3,6-三甲基苯甲醛（5.94％-25.52％），L-柠檬烯（4.69％-27.44％），α-pine烯（7.64％-12.43％） ，β-月桂烯（3.44％-10.38％）和L-水芹烯（2.90％-9.75％）。结果表明，从不同地区收集的植物具有不同的化学组成。根据报告的结果收集，选择和培养不同的基因型可以使育种者发展出用于油的提取和使用的化学型。
