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, Fe, Cu (CUPRAC), Fe-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 Fe reduction result was 0.940 (µg/mL), CUPRAC 1.183 (µg/mL), FRAP 0.963 (µg/mL), DPPH scavenging IC: 16.7 (µg/mL), and ABTS IC: 8.01 (µg/mL). hCA I enzyme inhibition results in IC: 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.
