Aim: In this study, it was aimed to compare the antioxidant activities of ethanol extracts prepared using ultrasonically assisted extraction (UAE) method of both peel and seed of rosehip fruits growing naturally in Gümüşhane province with the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) method.
Method: In this study, the antioxidant activity of the extracts of the peel and seed parts of the rosehip fruit prepared using UAE method at different time intervals was determined by 2,2-diphenyl-1-picryl-hydrazyl (DPPH) method.
Results: The free radical scavenging activity of IC50 value rosehip extracts of UAE assisted extraction for 2 minutes was calculated as 0.69 ± 0.005 mg mL-1 for the peel part and 0.39 ± 0.0007 mg mL-1 for the seed part. The seed part of the rosehip fruit has been found to have a higher radical scavenging activity than the peel part.
Conclusion: It has been concluded that the data obtained are more effective than the data available in the literature, and this is thought to be related to the extraction method used.
