Abstract :

Pomegranate (Punica granatum L.) is a native plant of Iran which cultivated throughout the country. Various metabolites and bioactive compounds have been reported from it. The plant has highly antioxidant potentials and possesses considerable phenolic ingredients. In order to study physico-chemical properties and qualitative attributes of pomegranate fruit juices in 25 genotypes of cultivar Malas, as the most famous Iranian cultivar, the experiment was accomplished in Agricultural Biotechnology Research Institute in Isfahan at October 2015. The fruits harvested from Pomegranate Genotypes Genetic Resources of Iran in yazd. Anthocyanin, polyphenol contents (by Folin-Ciocalteu), antioxidant capacity (by DPPH), total soluble solids and total acidity as the biochemical traits and taste, aril color, peel color, quality of aril color and aril quality as the qualitative characteristics were measured. Results showed that the highest acidity found in Malas Zoodras Kan and total soluble solids in Malas Naalout Baneh (18.53 Brix). Malas Nar Poost Ghermez Marivan had maximum antioxidant capacity. Malas Daneh Siah Bafgh and Malas Larz Galoubarik Ardestan had the highest contents of anthocyanin and polyphenols, respectively. Study of simple correlation among the attributes had no significant differences. According to the same conditions subjected to all plants in the collection, it concluded the premier genotypes could be used as applied purposes such as pomegranate anthocyanin production and/or high antioxidant.
