The growing demands of consumers for edible seed oils containing high unsaturated fatty acid and antioxidant content have resulted in considerable efforts to investigate plants as possible sources of oils and nuts. In this research, the amount of fatty acid compositions, total flavonoid, phenol and antioxidant properties of Pistacia atlantica and Pistacia khinjuk were evaluated. The kernel oil content of P. atlantica and P. khinjuk were 24.33 ± 0.333% and 31.00 ± 0.577%, respectively. Palmitic acid, Stearic acid, Oleic acid, Linoleic acid, and Palmitoleic acid were the main components in the oil of the two Pistacia species. The results showed that unsaturated fatty acids accounted for approximately 77.65% and 74.87% of total fatty acids in P. atlantica and P. khinjuk, respectively. The two Pistacia species were rich in phenolic compounds (130.77± 3.11 and 126.91± 4.41 mg quercetin/100 g oil) and had high antioxidant properties (4.545± 0.655 and 15.733± 0.689 mg/g oil) in P. atlantica and P. khinjuk, respectively. Oil content and Oleic acid of the two species of Pistacia are shown/known to be higher than some other edible oils. This research showed that the kernel oil of the two species of Pistacia have the same value in terms of quality, taste and natural antioxidant qualities with other edible oils.

The grape berries due to containing organic acids, sugars, aromatic compounds, phenolic compounds (including anthocyanins, flavanols, flavonols, stilbenes (resveratrol)), tannins, and oil in the pulp, skin, and seed have numerous health benefits for human health. In this study, we investigated genetic and phytochemical characteristics of four famous grapevine cultivars (Shiraz, Sirch, Panje Arous, and Yaghouti) at the maturity stage in 10-20º Brix on a cultivar basis. This research was performed at university of Hormozgan in 2017. The results indicated that Sirch cultivar had the highest total anthocyanin content (2733 mg kg-1 FW), total phenolic content (1666 mg kg-1 FW) and total carotenoid in the skin. High correlation (R2 = 0.951) was observed between cultivars skin’s total anthocyanin and total carotenoid contents. The highest quercetin content (1593 mg kg-1 FW) among the studied cultivars was obtained in Panje Arous cultivar (a pink grape) and Sirch cultivar had the highest delphinidin specific anthocyanin content (65.03 mg kg-1 FW). Among the studied cultivars, Shiraz had the highest total soluble sugar (%19.90) and amount of vinegar (950 ml Kg -1 grapes). Analysis of GC-MS results of vinegar, indicated that the highest rate of ethanol (%98.442) was found in Panje Arous cultivar. DNA sequencing and alignment analysis of F3H, UFGT, DFR, and MybA1 gene sequences showed that there was high homology (>%99) among the studied cultivars, therefore it can be concluded that they are derived from a common ancestor.
