Extraction conditions and identification of volatile organic compounds from umbu pulp by HS-SPME/GC-MS

Abstract despite the high social and economic importance of Spondias tuberosa Arruda, to best our knowledge there are very few detailed studies on volatile compounds this fruit popularly named umbu. Therefore, aim study was find extraction conditions by solid-phase microextraction in headspace mode (HS-SPME) determine from umbu pulp gas-chromatography coupled mass spectrometry (GC-MS). The optimal were obtained using 4 g 0.2 NaCl/pulp (w/w), maintained for 10 min incubation at 40 °C. SPME-fiber exposed 20 then desorption. Thus, a total 25 detected 16 identified under these conditions, with 9 being first time fraction two genus. major chemical class terpenes esters, which together represent more than 90% chromatographic area.
