Wild rose wines have high phenolic and ascorbic acid content.
High antioxidant activity of wines fromR. rugosaandR. caninaconfirmed.
Wild rose wines reduce mutation intensity induced by MNNG in dose-dependent manner.
The purpose of this study was to determine the concentration of biologically active compounds (polyphenols andl-ascorbic acid) inRosa caninaL. andRosa rugosaThunb. wines. The antioxidant capacity and antimutagenicity of the wines were also investigated. Aged and young wines contained phenolics levels of 2786–3456 and 3389–3990 mg/L GAE, respectively. The final concentrations of ascorbic acid were 1200 forRosa rugosaThunb. and 600 mg/L forRosa caninaL.R. rugosaandR. caninawines revealed high antioxidant activity in different assays (with ABTS, DPPH, and DMPD radicals). Expressed in terms of Trolox equivalent antioxidant capacity (TEAC), the activity ranged from 8 to 13.5 mM. Significant differences were found between the tested wines terms of their reactivity against the ABTS and DMPD radicals. The wines inhibitedin vitroN-methyl-N′-nitro-nitrosoguanidine (MNNG) and the number of induced His+revertants increased in a dose-dependent manner by 16–48% inSalmonellaTyphimurium TA98 and 12–52% inSalmonellaTyphimurium TA100. Wines from dog rose (Rosa caninaL.) showed a greater ability to reduce mutations.
