Abstract
Pomegranate is one of the important and an oldest fruit that is grown in vast regions. In recent years pomegranate juice is became a popular beverage. This study was carried out to investigate the mineral elements and some biochemical properties of juice in eight local Iranian pomegranate cultivars. The results showed a significant difference in the studied traits in all cultivars. The potassium content in pomegranate juice was higher than other elements, followed by calcium, sodium, phosphorus, magnesium, iron, manganese, zinc and copper. Potassium, calcium and iron was found the highest in chr('39')Golabichr('39'), meanwhile the highest amount of magnesium and sodium measured in chr('39')Sorahichr('39') cultivars. chr('39')Aliakbarichr('39') had the highest amount of manganese and zinc and chr('39')Lopsorkhichr('39') and chr('39')Mirzaeichr('39') had the highest value of phosphorus and copper, respectively. The lowest amount of potassium and iron was observed in chr('39')Lopsorkhichr('39') and chr('39')Aliakbarichr('39') cultivars, respectively. For other elements, chr('39')Garchr('39') had the lowest concentration. In terms of biochemical properties such as total soluble solids (TSS), maturity index (MI) and acidity (pH) of juice, chr('39')Golabi, Lopsorkhi and Sorahichr('39') cultivars had the highest value. chr('39')Sorahichr('39') and chr('39')Aliakbarichr('39') cultivars with the highest amount of titrable acid were sour and suitable for industries pomegranate production, which require sour taste. Other cultivars were introduced due to the proper amounts of mineral elements and sweet and sour taste for fresh consumption and pomegranate juice production industry. The two-dimensional graph, based on the principal components analysis, confirmed the results of grouping the cultivars based on the comparison of the mean.

Abstract
Russian olive is one of plants belonging to the Elaeagnacea family. The aim of this study was investigating the diversity of fatty acids in seeds of some populations of Russian olive. Soxhlet apparatus was used to extract oil and chromatography was used to identify the compounds of fatty acids. The lowest and highest percentage of oil was seen in the populations of Shahrekord, Naein 1 and Semirom, respectively. The observed saturated fatty acids were myristic, palmitic, stearic, arachidonic, behenic and lignoceric acid. The highest percentage of saturated fatty acids was found in the population of Shahrekord (31.32±0.2) and the lowest percentage was seen in the sample of Semirom (2.70±0.15) without significant differences with the samples of Mimeh, Kohiaye, Naein 1 and 2, and Zarrin-shahr. The observed unsaturated fatty acids were pentadecanoic acid, palmthiolic acid, oleic acid, linoleic acid, and linolenic acid. The population of Habibabad 1 (57.54±1.60) and Farokhshahr (55.41±1.60) have the highest percentage of monounsaturated fatty acids and Mimeh population (28.30±2.00) has the lowest percentage of monounsaturated fatty acids. Shahrekord population had the lowest percentage of polyunsaturated fatty acids. In clustering and at a distance of 25, the population of Shahrekord was separated from other populations and placed in a separate cluster. It seems that the difference between the percentages of oil has caused Shahrekord population to be placed in a separate cluster. At distance 25, the population of Shahrekord was separated from other populations and placed in a separate cluster, and at distance 5, three clusters could be separated, which can be discussed based on the diversity and composition of fatty acids. The results of this study revealed that there are noticeable variations in terms of oil percent and fatty acids composition in Russian olive in studied region which can be used in special purpose.
