Analysis of the Terpene and Sesquiterpene Hydrocarbons in Some Citrus Oils

open access: closedJournal of Food Science, 1965
SUMMARY The terpene and sesquiterpene hydrocarbons in various citrus essential oils are analyzed in a two‐step procedure. During the first step, the oxygen‐containing compounds are removed by column chromatography. In the second step, the terpenoid‐free oil is analyzed by gas chromatography, using a small sample to obtain the terpene ...

Occurrence and Preclusion of Terpene Chlorohydrins in Citrus Essential Oils

open access: closedJournal of Food Science, 2003
ABSTRACT: Screening commercial cold‐pressed oils revealed the presence of terpene chlorohydrins, which may have quality and safety implications for end‐users. Concentrations of (1R, 2R, 4R)‐2‐chloro‐8‐ p ‐menthen‐1‐ol in some citrus essential oils ranged from less than 1 ...

Terpene hydroperoxide chemistry in citrus oils; reaction with endogenous aldehydes to form peroxyhemiacetals

open access: closedFlavour and Fragrance Journal, 2016
AbstractLimonene and linalool are major components in many essential oils, and both readily autoxidize to form terpene hydroperoxides. These hydroperoxides are sensitizers capable of causing allergic contact dermatitis, so it is important to have accurate analytical methods for them in perfumery raw materials and formulations.

Citrus essential oils and main terpenes: chemical composition and good litholytic activity on gallstones

open access: closedVegetos, 2021
We studied the gallstone dissolving capacity of Moroccan citrus (C) essential oils; C. clementina, C. aurantium, C. sinensis and C. paradisi. Their litholytic activity was compared to that of their main constituents revealed by a gas chromatography-mass spectrometry (GC–MS) analysis; limonene, linalool and γ-terpinene and to the Methyl tertbutyl ether (

Registered Pesticides and Citrus Terpenes as Blackbird Repellents for Rice

open access: closedThe Journal of Wildlife Management, 2008
Abstract: Nonlethal management alternatives are needed to minimize bird depredation of agricultural crops. We conducted 8 caged feeding tests and 2 field studies to evaluate 2 registered fungicides (GWN‐4770, Gowan Company, Yuma, AZ; Quadris®, Syngenta Crop Protection, Greensboro, NC), a neem oil insecticide ...

The terpene limonene induced the green mold of citrus fruit through regulation of reactive oxygen species (ROS) homeostasis in Penicillium digitatum spores

open access: closedFood Chemistry, 2018
Herein, the dosage effect of limonene on the P. digitatum spore germination and its regulatory mechanisms were investigated. Results showed that limonene only at low concentrations displayed a stimulatory role, with the optimal concentration being 0.25 μL/mL. GC-MS and GC analysis revealed that limonene contents remained relative stable and no evidence
