Chemical Composition andIn VitroAnti-Wood-Decay Fungal Activities ofDysphania ambrosioidesLeaf Essential Oil From Taiwan

Abstract

We evaluated the leaf essential oil in whole or fractions of Dysphania ambrosioides with respect to their resistance to wood decay fungal activities in vitro of 4 fungi. The main ingredients with the greater anti-wood decay capability were also identified. Fresh leaves of D. ambrosioides were hydrodistillated in a Clevenger-type apparatus and the resulting oil characterized using GC-FID and GC-MS instruments. The essential oil was found to consist of α-terpinene (30.5%), p-cymene (17.3%), carvacrol (16.2%), and ascaridole (15.1%). The oil showed resistance to wood decay activity of Trametes versicolor, Phanerochaete chrysosporium, Phaeolus schweinitzii, and Lenzites sulphureu. The oil had excellent resistance to wood decay fungal activities, and the active compounds were shown to be carvacrol and ascaridole.

Chemical Composition, Antioxidant and Antibacterial Activities and Acute Toxicity of Cedrus atlantica, Chenopodium ambrosioides and Eucalyptus camaldulensis Essential Oils

“…The results obtained for Cedrus atlantica and Chenopodium ambrosioides samples are less important compared to previous researches; in fact, Skanderi et al [ 23 ] reported that Cedrus atlantica essential oil exerted a remarkable antioxidant efficacy. Similarly, the EO of Chenopodium ambrosioides harvested in Guercif had a similarly high antioxidant activity [ 48 ]. The change in the antioxidant potential of essential oils can be attributed to the presence of certain molecules that have antioxidant activity [ 49 ].…”

Bioactive compounds characterisation of PeruvianDysphania ambrosioides(L.) Mosyakin & Clemants leaves byGC/MSandUPLC–ESI–Q/TOF–MSntechniques

“…Hsu et al . (2022) found in essential oil of plants from Taiwan, α‐terpinene (30.5%), p ‐cymene (17.3%), carvacrol (16.2%) and ascaridole (15.1%); the authors also compiled the composition of the essential oil from different origins, finding great variability, which is supported by chemotypes from different geographical areas, climates, harvest times; as well as processing conditions. The importance in the identification of these compounds of terpene nature lies in their therapeutic potentials, since they are associated with neuroprotective (Cho et al ., 2017), anti‐inflammatory, anticancer and antimicrobial effects (Kiyama, 2017).…”

“…Bezerra et al (2019) in plants grown in Brazil mainly reported a-terpinene (54.09%), ascaridole (15.13%), ascaridole epoxide (9.77%), p-cymene (4.87%) and carvacrol (4.57%); while Pavela et al (2018) for EO from plants grown in Western highlands of Cameroon found mainly, ascaridole (35.4%), p-cymene (29.2%) and trans-ascaridole (26.0%). Hsu et al (2022) found in essential oil of plants from Taiwan, a-terpinene (30.5%), p-cymene (17.3%), carvacrol (16.2%) and ascaridole (15.1%); the authors also compiled the composition of the essential oil from different origins, finding great variability, which is supported by chemotypes from different geographical areas, climates, harvest times; as well as processing conditions.

Simultaneous Hydrodistillation of Cedrus atlantica Manetti and Salvia rosmarinus Spenn: Optimization of Anti-Wood-Decay Fungal Activity Using Mixture Design Methodology

“…Indeed, essential oils are only mildly toxic to the environment and can exhibit higher biocidal activity. 13 Wood extracts constitute an important class of secondary metabolites. 14 Several wood species seem indebted to contain chemical compounds.…”
