Effect of Different Fruit Sizes on Essential Oil Ratio and Components of Coriander

Abstract:

The present research was conducted to determine the effects of different fruit sizes on essential oil content and major essential oil components of coriander in the year 2012. Two different coriander cultivars (Arslan and Gürbüz) and three different sieve sizes (2, 3.15 and 4 mm) were used to separate the fruits into different size groups. Results revealed that essential oil contents varied between 0.23 - 0.34 %. Essential oil content of cultivar Arslan decreased with increasing fruit sizes, but an increase was observed in essential oil contents of Gürbüz with increasing fruit sizes. Linalool was observed as the major component. Linalool contents of coriander cultivars varied between 85.66 - 78.94 %. Following the linalool, respectively γ-terpinene, camphor and geraniol were determined as the other major components. The fruit size group of A1 (2 - 3.15 mm) of cultivar Arslan yielded the highest essential oil content (0.34 %) and the highest linalool content (85.66 %).
