Antioxidant activity and antioxidants of raspberry and mulberry fruit

Mulberry (Morus nigra L.) and raspberry (Rubus caesius L.) are particularly desirable fruits in Iran. More recently, the interest in these mulberry and raspberry fruits has also increased because of the population of healthy properties of these fruits. The study was carried out in 2013 aiming to determine the antioxidant activing (2, 2-diphenyl-1-picrylhyrazyl, DPPH), total phenolic, total anthocyanin and ascorbic acid of mulberry and raspberry species grown in Iran. The results show that mulberry species has higher bioactive contents than raspberry species. The average total phenolic content and total anthocyanins of mulberry species was 345.77 mg GAE /100gFW and 75.7 mg/100g FW.In raspberry, these values were 242.97 mgGAE/100gFW and 50.14 mg /100gFW. The average antioxidant activity of mulberry species was also found to be higher than that of the raspberry ones according to DPPH assay.
