Daffodil is a valuable plant for the cosmetic, pharmaceutical, therapeutical and industrial traits, and become an important in the Mediterranean region of Turkey. The volatile compounds of daffodil flowers were compared using HS/SPME-GC/MS (Headspace/Solid Phase Micro Extraction-Gas Chromatography Mass Spectrometry) techniques grown in different salinity stress (0, 10, 20, 30, 40 mM NaCl) conditions. In the study 38 volatiles compounds were detected depending on the salinity treatments. The detected compounds belong to aldehydes, alcohols and terpenes chemical classes. It was pointed out that the presence and concentrations of 14 terpenes were influenced by the used salt concentrations. Monoterpenes were major component among the terpenes. Ocimene, myrcene, delta-3-carene and a-pinene among the moneterpenes were detected in higher percentages. In conclusion, a decrease in the total aldehyde and alcohol content was determined in daffodil flowers; whereas, an increase was identified in terpenes (mostly monoterpenes) under salinity stress. The most remarkable decrease ratio was determined to be hexanal as aldehydes and 3-hexen-1-ol as alcohols. On the other hand, the most remarkable increase ratio was found to be ocimene content as monoterpenes under higher salinity stress condition. Ocimene content, with 80.91 %, in the 40 mM NaCl which is the highest salinity stress, was significantly found high at a remarkable rate.
