Abstract
|
|
|
|
Essential oils extracted from plants have been attracted significant attention in recent years due to their pharmacological uses such as for sterilization and preservation. In this study, essential oil was extracted from needles, twigs, and barks of pine trees using three different types of solvents: acetone, petroleum ether, and toluene. The oil extraction ratio of these three different parts of pines trees by each type of solvent was investigated in detail. In addition, TLC and FTIR analysis were performed to analyze and identify the essential oil extracted from the pine trees. When acetone was used for the solvent, the extraction ratio showed the highest value with the needles and decreased in the following order: needles > twigs > barks. In contrast, petroleum ether and toluene resulted in the highest extraction ratio with the twigs followed by the needles and barks. Although the boiling points of acetone and petroleum ether are similar, the average oil extraction ratio of the pine tree by acetone showed 4.3 times higher than petroleum ether attributed to the high polarity of acetone.
