Abstract
Abstract. Dahlia is a genus of flowering plants of about 35 to 40 species, distributed mainly in Mesoamerica. The aim of this work was to study the chemical composition of the leaflet and capitulum essential oils of D. imperialis growing wild in Costa Rica. The essential oils were obtained by hydrodistillation in a modified Clevenger apparatus. The chemical composition of the oils was performed by capillary gas chromatography with a flame detector (GC-FID) and gas chromatography-mass spectrometry (GC-MS) using the retention indices on a DB-5 type capillary column in addition to mass spectral fragmentation patterns. A total of 131 compounds were identified, accounting for 96.5-99.3 % of the total amount of the oils. The major constituents in the leaflet oil were β-pinene (35.2 %), α-phellandrene (21.9 %), α-pinene (18.0 %), p-cymene (8.3 %), limonene (4.3 %) and γ-muurolene (3.9 %). The major constituents in the capitulum (flower head) oil were β-pinene (27.7 %), α-phellandrene (26.2 %), α-pinene (12.4 %), β-phellandrene (6.6 %), limonene (5.6 %), (E)-β-ocimene (2.9 %), and germacrene D (2.2 %). This is the first report about the chemical composition of essential oils from D. imperialis.

摘要大丽花是开花植物的一个属,约有35至40种,主要分布在中美洲。研究了哥斯达黎加野生帝王花小叶和小头叶精油的化学成分。在改良的Clevenger装置中通过加氢蒸馏得到精油。采用毛细管气相色谱-火焰检测器(GC-FID)和气相色谱-质谱联用(GC-MS),采用DB-5型毛细管柱上的保留指数和质谱破碎图谱进行化学成分分析。共鉴定出131种化合物,占总含量的96.5- 99.3%。小叶精油的主要成分为β-蒎烯(35.2%)、α-茶香烯(21.9%)、α-蒎烯(18.0%)、对伞花烯(8.3%)、柠檬烯(4.3%)和γ-茂烯(3.9%)。头状花序油的主要成分为β-蒎烯(27.7%)、α-香蒜烯(26.2%)、α-蒎烯(12.4%)、β-香蒜烯(6.6%)、柠檬烯(5.6%)、(E)-β-香蒜烯(2.9%)和芽孢烯D(2.2%)。本文首次报道了帝王花精油的化学成分。Resumen。大丽花属植物,主要分布在中美洲,有35个或40个品种。研究目的:研究目的:确定研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:研究目标:哥斯达黎加。链接extracción del aceite se efectuó phidrodestilación con equipo clevenenger modificado。La composición química del aceite se analizó mediante las tacimnicas de cromatografía gaseoso-líquida con detector de ionización de llama (GC-FID) y de cromatografía gaseoso-líquida acoplada a un detector selectivo de masas (GC-MS)。通过与fragmentación de masas的赞助人的比较,我们利用了índices de retención obtenidos,并将其与DB-5进行了比较。共鉴定出131台计算机,对应96.5- 99.3%的漏报率。Los compones mayoritarios del aceite de Los fololos fueron β-pineno(35.2%)、α-felandreno(21.9%)、α-pineno(18.0%)、p-cimeno(8.3%)、柠檬eno(4.3%)和γ-muuroleno(3.9%)。Los components mayoritarios del aceite de Los capítulos florales fueron β-蒎烯(27.7%)、α-felandreno(26.2%)、α-pineno(12.4%)、β-felandreno(6.6%)、柠檬eno(5.6%)、(E)-β-ocimeno(2.9%)和germacreno D(2.2%)。Este es el primer informe acerca de la composición química de aceites esenciales de D. imperialis。
期刊介绍:
The Journal of the Mexican Chemical Society (J. Mex. Chem. Soc.) is a scientific, blind, peer reviewed, and open access, free of charge publication that covers all areas of chemistry and its sub-disciplines (i.e. medicinal chemistry, natural products, electrochemistry, material science, computational chemistry, organic chemistry, bionirganic chemistry, etc). It is devoted to facilitating the worldwide advancement of our understanding of chemistry. It will primarily publish original contributions of research in all branches of the theory and practice of chemistry in its broadest context as well as critical reviews in active areas of chemical research where the author has published significant contribution. The J. Mex. Chem. Soc. is a quarterly publication which language of submission and publication is English. To be suitable for publication in J. Mex. Chem. Soc., manuscripts must describe novel aspects of chemistry, high quality of results and discussion an excellent bibliographic support, and contribute to the development of the field. Routine or incremental work are not suitable for publication in J. Mex. Chem. Soc. Authors are encouraged to send contributions in electronic form. Our online submission system guides you stepwise through the process of entering your article details and uploading your files.
