Resumen :
This research presents, for the first time, full volatile profiles of four aerial parts of caper plants (Capparis spinosa L.) from
southeastern Spain. Volatile compounds in caper leaves and stems (together), flowers, flower buds, and fruits from two cultivars
were identified and quantified using headspace-solid phase microextraction (HS-SPME) and gas chromatography with a mass
spectrometry detector (GC-MS). Forty-three volatile compounds were identified in the caper shoots, 32 in caper flowers, with only
18, 10, and 6 compounds being found in flower buds, leaves, and fruits, respectively. *e predominant compound in all studied
materials was methyl isothiocyanate, with nerolidol, trans-2-hexenal, and nonanal playing key roles in flowers, leaves, and flowers
buds, respectively. *e two studied cultivars had the same volatile compounds but at very different concentrations, although the
two studied cultivars are cultivated under the same climatic and agronomic conditions. Additionally, the predominant compounds, especially methyl isothiocyanate (6882 mg·kg−1 fw in flower buds of ORI 3 cultivar), can be separated and concentrated
for future applications in food technology.
