Pinus nigra extractives analysis for green growth

Abstract

This study aimed to determine all the extractives from Pinus nigra. Different samples were collected from heartwood, sapwood and bark. A Soxlet device and three different solvents (water, ethanol, dichloromethane) were used to collect the extracts. Chemical analyses were conducted with GC-MS (Agilent 5975C). The results revealed significant amounts of the chemical compounds, such as phthalic acid, squalene, linoleic acid, ethyl oleate, propenoic acid, isopropyl myristate and humulen, which have many applications in green chemistry, novel – functional food and pharmaceutical industries and can be used for green growth, circular economy and environmental integration at the aspect of more effective use of natural resources and forest recovery.

Pinus brutia extractives analysis for sustainability

“…Extractives are chemical compounds inside cell walls, more rarely in cell cavities, with various synthesis, such as aromatic phenolic compounds, aliphatic compounds, terpenes, terpenoids and others. Since there is no chemical attachment to the wood, extractives can be removed from it with the use of various solvents, for example hot water, methanol, ethanol, dichloromethane and others, without causing transformation of it [4][5][6][7][8][9]. Of the genus Pinus several species are native in Greece, such as Pinus brutia, Pinus nigra, Pinus pinea, Pinus leucodermis, Pinus peuce and others [10,11].…”
