Phytochemical Compounds of Branches from P. halepensis Oily Liquid Extract and S. terebinthifolius Essential Oil and Their Potential Antifungal Activity

“…The lipophilic extractives (resin acids, terpenes, fatty acids, glycerides, steryl esters, sterols) were extracted using n-hexane then the hydrophilic ones (stilbenes, flavanols, monosaccharides, sugar alcohols) with acetone/water from sapwood and heartwood of P. halepensis stem [62]. Additionally, lipophilic and hydrophilic extractives were analyzed with GC-MS that were more abundant in heartwood than in sapwood of P. halepensis [63]. Seed oil of P. halepensis extracted with hexane was rich in fatty acid composition with linoleic and oleic acids accounting for more than 76% [64].…”

Recovery of Bioactive Compounds from Hazelnuts and Walnuts Shells: Quantitative–Qualitative Analysis and Chromatographic Purification

“…The group assignment was comparable in both shells, including groups from long- to short-chain fatty acids, phenols derivatives (lignans, resin acids, and flavonoids) and monosaccharides. However, two peaks were observed in the HS at early retention times (between 19–19.5 and 20.5–21.5), which could be attributed to triglycerides and steryl esters [ 30 , 32 ]. The resolution of these chromatograms was not enough to clearly observe the peaks from individual components, but this overview was useful to know the distribution of some target compounds that were subsequently separated by means of flash chromatography.…”

Volatile Organic Compounds (VOCs) from Wood and Wood-Based Panels: Methods for Evaluation, Potential Health Risks, and Mitigation

“…The Soxhlet apparatus has been used in a number of studies for the extraction of various sample components, including volatile and semivolatile compounds [ 52 , 61 , 65 , 89 ]. In principle, a repeated extraction of a solid sample is performed with condensed vapor of hot solvent in a glass apparatus.…”

“…Benouadah et al [ 65 ] studied the variance between heartwood and sapwood of Pinus halapensis, concluding lipophilic extractives (resin acids, terpenes, fatty alcohols) were a little more abundant in heartwood (1.6%) than in sapwood (1.1%). The content of acetic acid, in general the main volatile acid in wood, was slightly higher in sapwood than in heartwood.…”
