Abstract
This experiment was conducted to study the effect of south-west climatic conditions on quantitative and qualitative of fatty acids in dog rose (Rosa canina L.) seeds collected from five regions including: Semirom (Isfahan Province), Kiar and Gerdbishe (Charmahal and Bakhtiari Province), Yasuj and Meymand (Kohgiluye and Boyer Ahmad Province). Oil was extracted using Soxhlet apparatus; the fatty acid composition of oil was characterized and quantified using GC. The highest and lowest oil percentage obtained from Meymand (11.05%) and Kiar (8.15%), respectively. The results confirmed the presence of five dominant fatty acids in seeds of dog rose, including: linoleic, oleic, linolenic, palmitic and stearic acid, respectively. Results showed that differences between fatty acids quantity in regions under study was significant (P
