Analysis of volatile compounds of tapereba (Spondias mombin L.) and caja (Spondias mombin L.) by simultaneous distillation and extraction (SDE) and solid phase microextraction (SPME)

Volatile compounds of caja and tapereba fruits, both classified as Spondias mombin, but from different geographic origins, were extracted (and analyzed) using solid phase microextraction (SPME) and simultaneous distillation and extraction (SDE). Forty-eight compounds were identified in tapereba and 47 in caja by SPME using a DVB/CAR/PMDS fiber. (E)-Caryophyllene (18.7%), ethyl butyrate (10.0%), and ethyl hexanoate (7.0%) were the most abundant components in tapereba volatiles extracted by SPME, whereas myrcene (41.1%) and,8-phellandrene (8.5%) were the major compounds in caja. In the tapereba SDE extract, 46 substances were identified, and (2)-caryophyllene (13.2%) and limonene (9.5%) were predominant. From the 42 substances found in the SDE extract of caja, the major components were myrcene (38.0%) and p-cymene (6.2%). The two fruits showed similar chromatograms upon the use of SDE and SPME. These methods made it possible to determine 30 identical components in both fruits by using SDE and 32 by using SPME.
