Abstract
|
The current study screened the oil content, fatty acids profile, and antioxidant properties of twelve Iranian sumac fruit accessions. The oil contents were variable among the investigated populations (ranging from 5.15 to 16.70%). Oleic acid (32.3–47.41%), palmitic acid (18.90–36.29%), and linoleic acid (10.31–35.39%) were the predominant fatty acids in the oil samples. According to principal component and cluster analysis, sumac germplasms were categorized into three groups: i.e., group I (five populations rich in linoleic acid), group II (four populations rich in oleic acid), group III (three populations rich in palmitic acid). The highest fruits weight, oil percentage, and linoleic acid content was obtained from Arasbaran population. Arasbaran population possessed the highest ∑PUSFA (i.e, 34.53%) and ∑UNSFA: ∑SFA ratio. Meanwhile, Paveh population possessed the highest antioxidant attributes. Such variabilities provide the possibility of using elite populations containing a high ratio of unsaturated fatty acids and antioxidant compounds in the food industry.
