CORPAS, Eduardo J; TABORDA, Gonzalo; TAPASCO, Omar A  e  ORTIZ, Aristófeles. Comparison between extraction methods to obtain volátiles from lulo (Solatium quitoense) pulp. Rev.Colomb.Quim. [online]. 2016, vol.45, n.3, pp.12-21. ISSN 0120-2804.  https://doi.org/10.15446/rev.colomb.quim.v45n3.61359.

Simultaneous Distillation-Solvent Extraction (SDE) and Headspace Solid Phase Micro-extraction (HS-SPME), coupled to Gas Chromatography-Mass Spectrometry (GC-MS), for recovery of volatiles from lulo pulp (Solanum quitoense) were compared. A completely randomized SDE/GC-MS design was applied to establish differences between the areas obtained with different solvents, whereas a two-way HS-SPME/GC-MS indicated the most appropriate extraction conditions of volatiles, having the type of fiber and the adsorption temperature as factors. SDE/GC-MS mainly promoted the extraction of hydrocarbons, aldehydes, and esters; whereas esters and aldehydes had higher areas using HS-SPME/GC-MS. Furthermore, the variance analysis showed a significant interaction among the type of fiber, the adsorption temperature, and the functional groups.
