Abstract :Objective: The aim of this study was to comparatively investigate the fruit and fruit stalks of Crataegus monogyna Jacq. and Crataegus laevigata (Poir.) DC collected from the Denizli/Türkiye region in terms of total phenolic content (TPC), DPPH radical scavenging activity, and macro and micro element compositions. Material and Methods: Fruit and fruit stalk samples of C. monogyna and C. laevigata species were utilized. Methanolic extracts were derived from dried samples, and TPC (Folin-Ciocalteu method) and DPPH antioxidant activity were determined spectrophotometrically. Macro (P, K, Ca, Mg, S, Na) and micro (Fe, Cu, Mn, Zn, B) element concentrations were analyzed using an ICP-AES device. The obtained data were statistically evaluated by two-way analysis of variance and Box Plot analysis. Results: The results indicated statistically significant differences (p<0.05) for most of the investigated parameters both between hawthorn species and between plant parts (fruit and stalk). Furthermore, significant interactions were detected between species and plant part. It was determined that TPC and DPPH activity were higher in fruit stalks compared to fruits. The highest TPC was measured in C. monogyna stalks (31.50 mg GAE/g DW), while the highest DPPH activity was observed in C. laevigata stalks (385.01 µmol TE/g DW). Macro and micro element contents also significantly varied depending on the species and plant part; P, Ca, Mg, S, Na, Fe, Cu, Mn, and Zn were generally found in higher concentrations in fruit stalks, whereas K content reached its highest value in C. laevigata fruit. Conclusion: This study revealed that the fruits and particularly the fruit stalks of C. monogyna and C. laevigata are rich sources of bioactive compounds and minerals. Diversity among species and plant parts can be used to assess the nutraceutical and pharmaceutical potential of these species and can also be taken into account in breeding programs aimed at developing new hawthorn cultivars with targeted traits.
