SESQUITERPENE RICH VOLATILE SEED OIL OF TAGETES PATULA L. FROM NORTHWEST IRAN

Hydrodistilled volatile seed oil composition of commonly growing ornamental Tagetes patula L. was analyzed for its constituents by GC/MS. Forty constituents were identified, comprising 94% of the total oil. Sesquiterpene hydrocarbons (52.7%) and oxygenated sesquiterpenes (15.8%) were the main subclasses of volatile oil components followed by monoterpene hydrocarbons (12.6%). The principle constituents of the volatile oil were (E)-caryophyllene (44.6%) caryophyllene oxide (14.8%), germacrene D (3.8%), (Z)-β-ocimene (3.8%) and limonene (3.7%). From chemical point of view, oxides (15.7%) were the predominant group of components with caryophyllene oxide as their main representative. α-terthienyl (3.8%) comprised partially large amount in the volatile oil content despite of its polar and less-volatile nature. Taking into account the volatile oil profile, the chemical composition of the volatile seed oil of commonly growing ornamental T. patula L. was characterized as sesquiterpene and α-terthienyl rich one probably with appreciable biocidal (Insecticidal and nematicidal) and pharmacological potential

Essential Oil Composition of Hydroponically Grown Chrysanthemum balsamita L

Abstract: Essential oil composition of Chrysanthemum balsamita L., Asteraceae, was evaluated in response to hydroponic production system. Hydrodistilled essential oil of air dried aerial parts has been studied for their constituents by GC-MS. Twenty two components were identified representing 94.52 % of the oil. Oxygenated monoterpens (79.03 %) and sesquiterpene hydrocarbons (13.59 %) were the major class of identified compounds occurring in higher proportions. The main components of the essential oil were carvone (42.53 %), α-thujone (21.3%) and β-bisabolene (10.56 %). Trans-p-mentha-2,8-dienol (3.0 %), β-thujone (2.21 %) and β-cubebene (2.21 %) were also present in significant amount. According to the volatile oil profile, hydroponic production system was comparable with previously reported field grown plants
