Volatile compositions of safflower (Carthamus tinctorws L.) genotype flowers cultivated under rainfed and irrigated conditions

Abstract

The aim of this study is to investigate essential oil composition of the flowers of 14 Carthamus tinc-torius L. (Safflower - Asteraceae) lines and varieties developed selection breeding method and their reaction to rainfed and irrigated conditions. Essential oil was extracted from dried flowers by SPME, which were then analyzed by using GC-FID and GC/MS for determining full composition. According to GC/MS results, fifty three compounds representing between 70.7-97.1% of the volatiles were characterized. In all samples except one sample, the main component was found to be phe-nylpropanoid derivative which is called 2-methyl-5-(4-methylpentyl)-3-propylphenol. Also, there is no statistical difference between rainfed and irrigated condition in terms of proportion of volatile components except one sample
