“…The in vitro antioxidant activity of d ‐limonene was evaluated by six different antioxidant assays, that is DPPH, ABTS, FRAP, iron chelating, hydroxyl and superoxide radical scavenging using Trolox as a positive control. d ‐limonene possessed significant antioxidant activity with IC 50 values for different assays were 384.73, 603.23, −589.85, −18475.5, 442.75 and 692.89 µmol/L, respectively, whereas for Trolox, the IC 50 values were found to be 153.30, 203.37, −171.73, 225.96, 146.37 and 105.25 µmol/L, respectively 89 …”

Anethum graveolens L. (dill), a member of Umbelliferae family, is an important essential oil‐bearing herb native to the Mediterranean and West Asia. It is well documented for its medicinal and traditional uses. The chemical composition of dill seed essential oil showed the presence of numerous volatile compounds with carvone, limonene, α‐phellandrene, β‐phellandrene and p‐cymene being the major ones in almost all its aerial parts. Thus, the main focus of this updated review is to highlight the biological importance of dill essential oil and its major constituents (carvone and limonene) reported till date. Although the number of reviews has been published on its chemical composition and medicinal uses, its role in the field of agriculture to develop commercial formulations is still needed to be explored. In brief, the information presented in this review will be useful in creating interest in the use of dill essential oil and its major constituents for the development of commercial plant‐based pesticides.

“…It is toxic for some herbivore species [ 43 ] and is an allelopathic agent in hot and dry climates [ 44 ]. Moreover, limonene has chemopreventive, antitumoral [ 45 ], hypoglycemic [ 46 ], antioxidant [ 47 , 48 ] anti-inflammatory [ 46 ], antibacterial [ 49 ], and antifungal [ 50 ] properties.…”

Trichoderma Strains and Metabolites Selectively Increase the Production of Volatile Organic Compounds (VOCs) in Olive Trees

et al. 2021

Plants emit volatile organic compounds (VOCs) that induce metabolomic, transcriptomic, and behavioral reactions in receiver organisms, including insect pollinators and herbivores. VOCs’ composition and concentration may influence plant-insect or plant-plant interactions and affect soil microbes that may interfere in plant-plant communication. Many Trichoderma fungi act as biocontrol agents of phytopathogens and plant growth promoters. Moreover, they can stimulate plant defense mechanisms against insect pests. This study evaluated VOCs’ emission by olive trees (Olea europaea L.) when selected Trichoderma fungi or metabolites were used as soil treatments. Trichoderma harzianum strains M10, T22, and TH1, T. asperellum strain KV906, T. virens strain GV41, and their secondary metabolites harzianic acid (HA), and 6-pentyl-α-pyrone (6PP) were applied to olive trees. Charcoal cartridges were employed to adsorb olive VOCs, and gas chromatography mass spectrometry (GC-MS) analysis allowed their identification and quantification. A total of 45 volatile compounds were detected, and among these, twenty-five represented environmental pollutants and nineteen compounds were related to olive plant emission. Trichoderma strains and metabolites differentially enhanced VOCs production, affecting three biosynthetic pathways: methylerythritol 1-phosphate (MEP), lipid-signaling, and shikimate pathways. Multivariate analysis models showed a characteristic fingerprint of each plant-fungus/metabolite relationship, reflecting a different emission of VOCs by the treated plants. Specifically, strain M10 and the metabolites 6PP and HA enhanced the monoterpene syntheses by controlling the MEP pathway. Strains GV41, KV906, and the metabolite HA stimulated the hydrocarbon aldehyde formation (nonanal) by regulating the lipid-signaling pathway. Finally, Trichoderma strains GV41, M10, T22, TH1, and the metabolites HA and 6PP improve aromatic syntheses at different steps of the shikimate pathway.

“…Among the identified volatiles, some of them were previously tested for their antioxidant properties. For example, limonene showed a concentration-dependent reduction in free radical formation through various in vitro assays [ 38 ]. Tested together with other terpenoids, it has been shown to be among the most potent scavengers of the free radical DPPH as well as having one of the highest reducing powers [ 39 ].…”

A Comparative Study of the Chemical Composition by SPME-GC/MS and Antiradical Activity of Less Common Citrus Species

Citrus secondary metabolites, such as terpene compounds, are very important for human health due to their bioactivity including anti-inflammatory, anti-cancer, and antioxidant effects. In this work, for the first time, the volatile chemical composition of peels and juices from four different Citrus species (C. junos, Citrus × aurantium, C. aurantium ‘Bizzarria’ and C. medica ‘Florentina’, commonly known as Yuzu jeune, Oni Yuzu, Bizzarria orange and Florence cedar, respectively) was investigated by Solid-Phase Microextraction-Gas Chromatography/Mass Spectrometry (SPME-GC/MS) technique and the antiradical activity was also examined. The results showed that limonene and γ-terpinene were the main volatile substances detected both in the juices and in the peels, followed by other minority compounds responsible for the phyto-complex of the unique aromas which characterize each individual analyzed Citrus species. Principal component analysis (PCA), performed on volatile compounds, showed both some correlation as well as a clear separation between the juice and the peel of each species. Among them, Oni Yuzu juice was found to be the richest in total polyphenols and flavonoids while its capacity to scavenge ABTS•+ and DPPH• radicals was similar to that of Yuzu Jeune and Bizzarria orange.
