Physicochemical Properties, Antioxidant Activities, and Chemical Compositions of Extracts Obtained from <i>Rosa pimpinellifolia</i> L. Flesh and Seeds Using Different Methods and Solvents

In this study, extracts were prepared from Rosa pimpinellifolia L. (RP) fruit flesh and seeds using different solvents by ultrasonic and classical extraction methods. Various physical and chemical properties of the fruit flesh, seeds, and their extracts were determined. The dry matter content; total soluble solids content; total sugar content; ash; protein; pH, L*, a*, b*, and increment E values; vitamin C; total phenolic content (TPC); total monomeric anthocyanin content (TMC); DPPH center dot and ABTS(center dot+) radical scavenging activities; and chemical compound and mineral substance composition of RP flesh and seeds were determined. A total of 113 chemical compounds were identified in the fruit flesh, seeds, and different extracts. It was revealed that aldehydes were the most abundant chemical compound group in the fruit flesh of RP (21.90%), while acids were the most abundant chemical compound group in its seeds (70.23%). The highest potassium content was found in RP flesh and seeds. The amount of mineral substances generally decreased in the extracts compared to the fruit flesh and seeds. Statistically, the effect of the part of the fruit and extraction method on the pH, L*, a*, b*, and increment E values, vitamin C, TMC, and ABTS(center dot+) radical scavenging activity was at the p < 0.01 level, while the effect of solvent type on pH, a* and increment E values, vitamin C, TPC, TMC, DPPH center dot, and ABTS(center dot+) radical scavenging activity was significant (p < 0.01). In terms of TMC and TPC, the most effective extraction method was the ultrasonic extraction method.
