Twenty seven species of rose hip are grown in different regions of Turkey. It is widely consumed as a tea after drying or processed into marmalade and juice (nectar). In this study, dry matter, lycopene, mineral content (Na, Mg. K, Ca, P), vitamin C, phenolic compounds, antioxidant activity of rose hip fruits grown in Bursa, Turkey and the same contents of theirs products were determined. Some significant changes and loss were fixed after processes. Generally, the highest mineral was Ca and the lowest was Na in fresh rose hip fruits and their products. It is suggested that fresh rose hip fruits and dried rose hips could be used as a source of antioxidant when vitamin C, lycopene and antioxidant activity were evaluated together. It was found that quercetin and (+)-catechin were the main phenolic acids in fresh rose hip fruits and processed rose hip samples.
