Chemical composition of volatile fractions of nine commercial hydrolats and corresponding essential oils obtained using an industrial process were studied. The hydrolat volatile fractions were reported for the first time. A comparative study of those obtained, on the one hand, by liquid-liquid extraction (LLE) and, on the other hand, using five solid-phase(More)
The variations of the elements that are examined most frequently during foliar analysis were determined for kiwi as a function of different nitrogen and potassium fertilizer loads. The values recorded demonstrated the existence of a relation between the leaves and the fruit. Two groups of elements were identified that exhibited different responses. The(More)
Fire is a dominant ecological factor in Mediterranean-type ecosystems. Forest management includes many preventive tools, in particular for fire prevention, such as mechanical treatments and prescribed burning. Prescribed burning is a commonly used method for treating fuel loads, but fuel reduction targets for reducing wildfire hazards must be balanced(More)
Polyphenol compounds were extracted from Myrtus communis L. berries (Myrtaceae) by maceration in 70% ethanol and analysed by HPLC-DAD and electrospray mass spectrometry. The Myrtus berries were collected at maturity from seven localities on the island of Corsica (France) and the sampling was carried out during three years. The polyphenol composition of(More)
The volatile and flavonoid compositions of the peel of Citrus medica L. var. Corsican fruits cultivated in Corsica were studied according to the maturity of the citron fruits measured using growing degree-days. Quantitative variation with the stage of development of the fruit was observed using gas chromatography, gas chromatography-mass spectrometry, and(More)
Fire spread across forest fuel is usually characterized by the rate of spread or the fireline intensity. The determination of the fireline intensity represents an essential aspect for understanding the behaviour of the fire and the involved combustion processes. The heat released during fire spread cannot be a-priori estimated from the fundamental(More)
In recent times, more and more studies have focused on flavonoids as biomarkers of environmental quality in aquatic plants, in particular, Posidonia oceanica (Linnaeus) Delile. It is therefore of interest to determine how different prehandling methods can affect flavonoid concentrations. The methods tested were (1) immediate extraction of fresh samples, (2)(More)
The volatile compositions of juice and peel of clementine (Citrus reticulata x Citrus sinensis var. Commune), mandarin (Citrus reticulata Blanco var. Willow Leaf) and their hybrids were analyzed by headspace solid-phase extraction (HS-SPME) coupled with gas chromatography and either a flame ionization detector (FID) or a mass spectrometer (MS). The major(More)
This work consist in sampling and analyzing smoke released by typical Mediterranean vegetation during a fire. To proceed we used an experimental apparatus made of an air sampling pump with a cartridge filled with Tenax<sup>reg</sup> TA. The sampling device was situated in a fixed place corresponding to the position of a fireman for the four studied(More)
BACKGROUND The effect of four cultivation parameters (post-maturity harvest date, storage period at 0 °C and input of nitrogen or potassium fertilisers) on the physico-chemical characteristics and composition of volatile compounds in kiwi fruit (Actinidia deliciosa) were evaluated. Five physico-chemical parameters were selected, namely, pH, total acidity,(More)
