Abstract
Chemical constituents of extracted oil from the nut of Pistacia atlantica kurdica (dried and fresh samples) - which grows in some regions of Kurdistan province in Iran - were extracted by using soxhlet method and analyzed by gas chromatography mass spectrometry. The main goal of this study was qualitative analysis of extracted compounds and optimization of extraction conditions. At three extraction times (7h, 11h and 13h) and with two solvents (n-hexane and methanol), soxhlet extractions were carried out. Extraction time and type of solvents were selected as two important factors. A general full factorial design with selected factors was used. The study reveals that n-hexane extracted more yield than methanol. The highest yield obtained with n-hexane, was 33.59%; while the highest yield obtained by methanol was 3.85%. The results show that when extraction is done by n-hexane, by increasing the extraction time up to 11h, the mass yield percent was also increased. The obtained chromatograms were showed that by increasing the extraction time up to 13h, the main extracted compounds were maintained but compounds with low quantities have been eliminated. The main compounds identified were alpha-pinene, decane, dodecane, tetradecane, hexadecane, palmitic acid, oleic acid and linoleic acid ester. The main identified compounds were nearly similar to dried and fresh samples. This study can be considered as the firs report on the chemical compounds of extracted oil from nut of Pistacia atlantica kurdica in studied region.
