Abstract

In Iranian traditional medicine Quercus brantii var. Persica (Jaub. & Spach) Zohary (Oak) is considered warm- and dry-natured. It is used for gastric pain, ulcer, anemia, hemorrhoids and rickets, burns, indigestion, diarrhea, and infection. Oak is readily available and has a variety of medicinal and health effects in both traditional and modern remedies. The main objective of this research is Identification in oak compounds, using Headspace-solid phase microextraction (HS-SPME) and Gas chromatography-mass spectrometry (GC-MS). Oak fruits were collected from Argavan Valley, Ilam, west of Iran, after drying and powdering, chemical compounds were isolated by HS-SPME and identified by using GC-MS method. The results analysis of Quercus brantii var. Persica revealed the existence of 41 chemical compounds. Major chemicals included beta- pinene oxide (8.65), Tetrahydro- linalyl acetate (8.51), 2-methoxy-p-cresol (7.65), 2- methoxy pyrazine (5.08), 2-acetyl pyridine, 2,3-dimethyl pyrazine (4.42), Trans- linalool oxide (3.79), beta- pinene(3.66), Verbenone (3.43), and Terpin-4-ol (3.27).
