Abstract
Headspace solid-phase microextraction HS-SPME) technique was employed to extract the volatile compounds from Pollen Pini. The volatile components were isolated and identified successfully by gas chromatography-mass spectrometry (GC-MS). The volatiles were collected using several SPME parameters (including extraction time and temperature). The best response was obtained using a PA fiber by when the extraction temperature was 70 degrees C, extraction time was 30 minutes and desorption time was 10 time. Analysis was performed by GC-MS. Seventy components were identified by HS-SPME. The main components were fatty compounds. The results showed that the HS-SPME technique could be used to extract the volatile components from HS-SPME-GC-MS.
