Chemical Composition and Antimicrobial Activity of the Essential Oil from Ambrosia trifida L.

Abstract

Abstract:The essential oil obtained by steam distillation of dried aerial parts of Ambrosia trifida L. from Northeast China was analyzed by GC and GC-MS. The essential oil yield based on dried plant material was 0.12% and thirty-five compounds (corresponding to 86.7% of the total weight) were identified. The main components were: bornyl acetate (15.5%), borneol (8.5%), caryophyllene oxide (8.3%), α-pinene (8.0%), germacrene D (6.3%), β-caryophyllene (4.6%), trans-carveol (2.9%), β-myrcene (2.6%), camphor (2.4%) and limonene (3.2%). A. trifida essential oil demonstrated bactericidal and fungicidal activity against six bacterial strains and two fungal strains, using the agar diffusion method.

Electrophysiological responses of four fungivorous coleoptera to volatiles of Trametes versicolor: implications for host selection

“…d-Cadinene and a-muurolene were reported as the major compounds in cultures of Lentinus lepideus (Hanssen 1982), while d-cadinene occurred also in Schizophyllum commune (Ziegenbein et al 2006) and in a wide variety of essential oil-producing plants (Joulain and König 1998;Kubeczka and Formáček 2002). Isoledene was found as volatile plant constituent in the liverwort Bazzania trilobata (Warmers and König 1999) and also in Ambrosia trifida (Asteraceae; Wang et al 2006). Six of these 15 compounds elicited reproducible antennal signals in tested beetles (Figs.…”

Chemical composition and pharmacological properties of the essential oils obtained seasonally fromLippia thymoides

“…Since sesquiterpene b-caryophyllene is the major constituent in all oils, it is likely that this constituent is not mainly responsible for the antimicrobial effect. Furthermore, essential oils constitute a mixture of various substances and variations on chemical composition can influence the antimicrobial activity, as observed in essential oils containing camphor, borneol, and camphene, which were effective against fungi and Gram-positive and negative bacteria (Alva et al, 2012;Cárdenas et al, 2012;Wang et al, 2006). Studies indicate that monoterpenes and sesquiterpenes induce alteration in the bacterial membrane, promoting disruption and increasing the permeability (Cristani et al, 2007;Kuroda et al, 2007;Trombetta et al, 2005).…”

“…Abieta-8,11,13-trien-7-one was other biogenic ketone also present in appreciable amounts. This product is a characteristic diterpenoid found in the essential oils extracted from the aerial parts of several species of the genus Chryptomeria (Su et al 1996), Aquilegia (Radulović et al 2007), Picea (Kinouchi et al 2000), Ambrosia (Wang et al 2006a), and Taiwania (Chang et al 2005).…”
