Zivzik pomegranate (Punica granatum) has recently sparked considerable interest due to its nutritional and antioxidant properties. To evaluate the antioxidant capacities of P. granatum juice, ethanol (EEZP), and water (WEZP) extracts from peel and seed, the antioxidant methods of 2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid radical (ABTS^•+) scavenging, 1,1-diphenyl-2-picrylhydrazyl free radical (DPPH^•) scavenging, Fe³⁺-2,4,6-tris(2-pyridyl)-S-triazine (TPTZ) reducing, Fe³⁺ reducing, and Cu²⁺ reducing methods were used. The antioxidant capacities of samples were compared with the most commonly used synthetic antioxidants, i.e., BHA, BHT, α-tocopherol, and Trolox. In terms of setting an example, the IC₅₀ values of EEZP for ABTS^•+ and DPPH^• scavenging activities were found to be lower than standards, at 5.9 and 16.1 μg/mL, respectively. The phenolic and flavonoid contents in EEZP peel were 59.7 mg GAE/g and 88.0 mg QE/g, respectively. Inhibition of α-glycosidase, α-amylase, acetylcholinesterase, and human carbonic anhydrase II (hCA II) enzymes was also investigated. EEZP demonstrated IC₅₀ values of 7.3 μg/mL against α-glycosidase, 317.7 μg/mL against α-amylase, 19.7 μg/mL against acetylcholinesterase (AChE), and 106.3 μg/mL against CA II enzymes. A total of 53 phenolic compounds were scanned, and 30 compounds were determined using LC-MS/MS. E. coli and S. aureus bacteria were resistant to all four antibiotics used as standards in hospitals.

Propolis is very significant in terms of its phytochemical content and biological activity among bee products. In this study, the antioxidant activities (total phenolic and flavonoid, Fe³⁺, Cu²⁺ (CUPRAC), Fe³⁺-TPTZ (FRAP) reducing, and DPPH^•, ABTS^•+ scavenging assays) of propolis collected from the Bitlis province of Türkiye were determined. In addition, the carbonic anhydrase I and II isoenzymes (hCA I and hCA II), α-glycosidase, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE) inhibition activity and phytochemical profile of propolis and mineral content were determined by LC-MS/MS and ICP-MS, respectively. In propolis, 31 phytochemicals were found, and the highest concentration of acacetin (23.604 mg/g) was detected. It is seen that the phytochemicals in propolis provide antioxidant properties. The mineral content was screened for 18 elements and determined to be rich in the elements that make up the salt content. Total phenolic content was 215.14 mg GAE/g, and total flavonoid content was 79.11 mg QE/g. The Fe³⁺ reduction result was 0.940 (µg/mL), CUPRAC 1.183 (µg/mL), FRAP 0.963 (µg/mL), DPPH^• scavenging IC₅₀: 16.7 (µg/mL), and ABTS IC₅₀: 8.01 (µg/mL). hCA I enzyme inhibition results in IC₅₀: 7.19 (µg/mL), hCA II 8.15, AChE 5.17, BChE 7.50, and α-Glycosidase 5.72. As a result of this study, it was determined that Bitlis propolis has high antioxidant properties and a rich phytochemical content. It was also observed that it is an effective enzyme inhibitor against epilepsy, glaucoma, Alzheimer’s, and diabetes, which are important diseases, and it can be evaluated in the treatment of these diseases and drug production.
