Babacan, Ebru Yüce; Demirpolat, Azize; Çakılcıoğlu, Uğur; Bagcı, Eyüp
The genus Opopanax W. Koch (Apiaceae) is represented by four species in Turkey. The composition of the essential oil of Opopanax genus members (Apiaceae) growing in Turkey was investigated in this study. GC-MS was used to analyze the composition of Opopanax essential oil samples that were taken from their natural environments. The Clevenger apparatus was used to hydrodistill the plant’s aerial parts, and the yields were determined to be between 0.2% v/w (for O. siifolius) and 0.4% (for O. hispidus, O. chironium, and O. persicus). The results and the chemical data provided some information and clues on the chemotaxonomy of the genus Opopanax. In this study, γ-elemene, butanoic acid octyl ester, and cylopropane were the main compounds identified in the essential oils of O. chironium, O. hispidus, and O. persicus. In particular, hexynyl n-valerate was most abundant in the essential oil of O. chironium, cyclopropane in that of O. hispidus, γ-elemene in that of O. persicus, and n-hexadecanoic acid/palmitic acid in that of O. siifolius. In a chemotaxonomic approach, the essential oil analysis of the Opopanax species revealed that these species conformed in a cluster analysis with their morphological classification. The constituents of the essential oils of all examined in the genus Opopanax were determined in this study, which is the most thorough one to date. This study provides new information about the composition of the essential oils of the investigated species.

Yuce, E.; Bagci, E.
The essential, oil of wild-growing Lallemantia iberica (Lamiceae) from Turkey was obtained by hydrodistillation and analyzed by GC and GC-MS. In the oil of the Lallemantia iberica, 40 components were characterized representing 90.1 % of the total oil, with germacrene-D (36.0 %), beta-caryophyllene (18.3 %) and bicyclogermacrene (9.7 %) as the main constituents. The results showed that the analysis of essential oil composition will add some contributions on the usability of this plant as a crop and renewable resources and chemotaxonomy of the genus patterns.

Bagci, Eyup; Yuce, Ebru
The essential oils from the aerial parts of two varieties (var. capitatum and var. luteum Robson) of Hypericum capitatum (Sect. Drosanthe) grown in Turkey were analyzed by GC and GC-MS. Forty-eight compounds were identified in the essential oils of var. capitatum with alpha-pinene (20.3 %), caryophyllene oxide (11.8 %), hexadecanoic acid (8.9 %), beta-caryophyllene (6.5 %) and undecane (3.8 %) as main constituents. Thirty-eight components were identified in the oil of var. luteum with camphor (15.3 %), germacrene D (10.5 %), beta-myrcene (7.4 %), caryophyllene oxide (6.5 %) and beta-cububene (6.3 %), as the abundant components. More quantitative and qualitative differences were determined between two varieties of H. capitatum essential oils. The results were discussed in means of renewable resources and chemotaxonomy.
