Abstract

Pomegranate (Punica granatum L.) is a native plant, which has many different cultivars in Iran. This plant consists of rich biochemical compounds that plays an important role in human health. This research aims to study some of biochemical compounds of this valuable fruit. Extract of pell and seeds and juice of fruits were prepared. According to the outcomes of this study, there is a direct relationship between increasing amount of phenol compounds and the colour of fruit peel. This increase showed significant difference. The anthocyanin measurement in three cultivars showed that the colour of the peel and seeds of the fruit has a direct relationship with the amount of anthocyanin. Study of antioxidant activity with the method of DPPH revealed that the highest amount of antioxidant activity between the peel and the seeds of the three cultivars of pomegranate is dedicated to the peel of the BSY. The outcomes of the FRAP method showed that the highest amount of antioxidant activity among seeds and the skin belongs to the seed of the WSR. With the use of the ABTS method the highest amount of antioxidant activity belongs to the peel of the BSY cultivar. The results of the studying vitamin C revealed that the amount of Vitamin C per 100ml of the pomegranate juice is 54.6±2.2mg for RSQ, 42.8±2.3mg for WSR and 65.7±2.2mg for BSY. Analysing the biochemical compounds from different cultivars helps to sufficient selecting, defusing and commercializing the pomegranate.
