in recent years, interest in use of plant sources due to function of Phytochemicals and antioxidant compound in maintenance of human health is increased, phenolic and flavonoid compounds are one of important compounds of plants that have antioxidant effects. Aim of the present study is to examine and comparison of phenolic and flavonoid compounds and antioxidant capacity of different organs of saffron, that every year a huge amount of them are wested during the processing of stigma. In this study, different parts of saffron were extracted by methanol (80%), then the amount of total phenol and flavonoid compounds was assayed by means of Folin-Ciocalteu and and Aluminium choloride methods respectively. The antioxidant activity was measured by DPPH free radical reduction. According to the results of this study, The highest content of total phenolic(6.43 mg GAE g-1 DW) and flavonoid (1.33 mg RU g-1 DW) was observed in stigma compared to other organs. The result of DPPH test also showed higher antioxidant capacity of stigma in comparison to other organs. Comparison of phenolic compounds in various organs showed that the content of these compounds and antioxidant activity could be different related to type of organs. Also, the higher antioxidant capacity in stigma and tepal compared to leaf and corm could be as a result of more phenolic compounds in these organs.
