Bioactivities of Ketones Terpenes: Antifungal Effect on F. verticillioides and Repellents to Control Insect Fungal Vector, S. zeamais.

Microorganisms

Pizzolitto RP, Herrera JM, Zaio YP, Dambolena JS, Zunino MP, Gallucci MN, Zygadlo JA.

Microorganisms. 2015 Nov 12;3(4):851-65. doi: 10.3390/microorganisms3040851.

Maize is one the most important staple foods in the world. However, numerous pests, such as fungal pathogens, e.g., Fusarium verticillioides, and insects, such as Sitophlilus zeamais, attack maize grains during storage. Many F. verticillioides strains produce fumonisins, one...

Ecol Evol. 2016 Mar 22;6(9):2854-64. doi: 10.1002/ece3.1810. eCollection 2016 May.

Plant responses to natural enemies include formation of secondary metabolites acting as direct or indirect defenses. Volatile terpenes represent one of the most diverse groups of secondary metabolites. We aimed to explore evolutionary patterns of volatile terpene emission. We...

Interaction of pre-attack and induced monoterpene concentrations in host conifer defense against bark beetle-fungal complexes.

Oecologia

Raffa KF, Smalley EB.
PMID: 28306839
Oecologia. 1995 Jun;102(3):285-295. doi: 10.1007/BF00329795.

Two pine species (Pinus resinosa, P. banksiana) responded to inoculation with fungi carried by bark beetles by rapidly increasing monoterpene concentrations at the entry site. Changes in total monoterpenes were more pronounced than changes in proportionate compositions. The extent...

Evaluating the Effects of Microwave-Assisted Hydrodistillation on Antifungal and Radical Scavenging Activities of Oliveria decumbens and Chaerophyllum macropodum Essential Oils.

Journal of food protection

Khajehie N, Golmakani MT, Eblaghi M, Eskandari MH.
PMID: 28371590

In this study, radical scavenging and antifungal activities of Chaerophyllum macropodum and Oliveria decumbens essential oils (EOs) extracted with microwave-assisted hydrodistillation (MAHD) were evaluated in comparison with the same EOs extracted by conventional hydrodistillation (HD). The final EO yields...

Fate of Terpene Compounds in Activated Sludge Wastewater Treatment Systems.

Journal of the Air & Waste Management Association (1995)

Terpene-based cleaners are being widely used in industrial cleaning formulations because of their ability to replace suspected ozone-depleting chemicals such as 1,1,1-trichloroethane and 1,1,2-trichloro-1,2,2-trifluoroethane (CFC-113). Substitution of chlorinated solvents with ter-pene-based cleaners, however, is expected to result in increased...
