| Summary: | Background: The aim of this study was to investigate the effect of environmental factors on the essentialoil yields (EOYs) and major essential oil components in the ripe fruits of Pistacia terebinthus L. (turpentinetree), which is a medicinal and aromatic plant. Fruit samples were collected from 34 different locationsof the turpentine tree growing wild in the Lake District in the Mediterranean Region of Turkey. EOYs (%,v/w) and essential oil component ratios (%) were determined in fruit samples by hydrodistillation andGC-MS methods, respectively. The effect of environmental factors on these variables were analyzedusing Pearson Correlation and Principal Component Analysis. Results: The essential oil yield of fruits collected from different localities ranged from 0.05% (v/w)to 0.19% (v/w). In terms of average values, α-pinene with 41.01% and limonene with 14.28% were themajor components in the essential oils of ripe fruits. Among the environmental variables, longitudeand sand % in 10-30 cm were the variables that made a statistically significant difference (p < 0.05)in fruit essential oil yield. According to the results of principal components analysis (PCA), α-pineneand Ocimene components were most affected by silt (%, 10-30 cm) and pH (%, 30-50 cm) ratios. Thelongitude and total annual precipitation (mm) were the most determining variables in the sabinene andlimonene components, respectively. It was seen that the total lime ratios at different depth levels of thesoils taken from the localities were the most effective variables for Myrcene and p-Cymene components. Conclusion: The study findings showed that EOYs and intended volatile component ratios in ripe fruitsof turpentine trees grown under appropriate environmental conditions can be increased. |
