| In this study, as preliminary research for the development of natural estrogen supplement the chemical properties of Iranian black pomegranate juice concentrate and seeds were evaluated. Proximate compositions of pomegranate juice concentrate and seeds were as follows; crude lipid 0.4% and 8.2%, moisture 39.9% and 6.6%, crude protein 0.9% and 12.2%, ash 1.4% and 1.7%, and carbohydrate 42.0% and 84.5% respectively. Major amino acids are glutamic acid (1310.0ppm) and aspartic acid (896.2ppm) in juice concentrate, and glycine (611.1ppm) and arginin (401.6ppm) in seeds. Ascorbic acid has the highest concentration of 20.0mg/l00g in juice concentrate and 0.23mg/l00 in seeds. The compositions of unsaturated fatty acids such as linoleic acid and linolenic acid were higher than those of saturated fatty acids such as stearic palmitic acid. Major minerals were potassium, calcium and sodium, potassium was highest in both juice concentrate and seeds. Vitamins were composed of ascorbic acid (20.0mg/l00g), vitamin B$_1$(0.12mg/100g) and niacin (0.80mg/l00g) in juice concentrate, and only ascorbic acid(0.23mg/l00g) in seeds. Organic acids such as citric and L-malic acid were detected only in pomegranate juice concentrate. The contents of total polyphenols were 4.55g/L in juice concentrate and 3.5mg/l00g in seeds, respectively. Phytoestrogens detected in pomegranate juice concentrate and seeds were daidzein, quercetin, genistein and 17 $eta$-estradiol. |
