The Allium turcicum L. (Zuzubak) plant as a cultivated vegetable have various health benefits and consumed as a food. Due to the shortcoming evidence in literature and the importance of this plant in folk medicine, in the present study, for the first time, we evaluated the bioactive profile of components (using LC-MS/MS), cytotoxicity, anticancer, antioxidant, and antibacterial prospectives of Zuzubak methanol extract. Reported results show that the extract is rich in bioactive compounds and has anticancer activity with breast cancer cells (MCF-7), human prostate cancer cells (DU -145), and Human osteosarcoma cancer Cell lines of (IC50) in dose dependent manner in the concentration range of 31.25 mu g/mL and 2000 mu g/mL for 24 and 48 h. Western blotting results determined that the extract significantly suppressed the growth of U2OS, MCF-7, and DU -145 cancer cells by down expression of Ang-1 (angiogenic protein) and Beclin-1 (autophagy protein) and overexpression of Bax (a proapoptotic protein). The oxidative stress indices showed a reduction in RPE-1 and MCF-7 cells and an upsurge in U2OS and DU -145 cells. Additionally, the antimicrobial assay showed suppression of the growth of various pathogenic microorganisms in 4.00 - 8.00 mu g/concentrations of Zuzubak extract using the microdilution method. The phytochemicals identified showed promising anticancer, antioxidant effects, and antimicrobial properties, representing a valuable herbal source for drug development studies.

Purpose The phenolic composition, antioxidant, antimicrobial activity, enzyme inhibition activity, and cytotoxic activity potentials of the plant Rumex acetosella L. (R. acetosella) were examined in this study. Materials and Methods: The chemical composition of R. acetosella methanol extract was identified by the LC-MS/MS method. The antioxidant activity was tested using beta-carotene/linoleic acid, DPPH free radical scavenging, ABTS cation radical scavenging, CUPRAC reducing power, and metal chelating activity methods. The cytotoxic activity was determined by the MTT assay using human ovarian adenocarcinoma (Skov-3), glioblastoma (U87), human dermal fibroblasts (HDF), and human colorectal adenocarcinoma (CaCo-2) cell lines. The antimicrobial activity of methanolic extracts was tested on gram-negative (Escherichia coli and Pseudomonas aeuriginosa) and gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) using the in vitro minimum inhibition concentration method (MIC). Enzyme inhibition activity of R. acetosella methanol extract was measured spectrophotometrically against acetylcholinesterase (AChE) and glutathione S-transferase (GST) enzymes. Results: The findings showed that the major components of the methanol extract content were luteolin-7-O-glucoside (1.599 m/L), polydatin (91,024 m/L), and shikimic acid (0.773 m/L). It was determined that the extract and standard antioxidant (a-tocopherol) results in DPPH center dot, and ABTS center dot + tests performed to determine the antioxidant activity were close to each other, and this value was more effective than the standard antioxidant (alpha-tocopherol) in the CUPRAC test. These results suggested that the plant's antioxidant potential was higher when compared with reference antioxidant compounds. It was determined that the methanol extract of R. acetosella had a weaker effect on the growth of the tested microorganisms than the antibiotics used as standard. The activity of the GST and AChE enzymes was found to be severely inhibited by the methanol extract of R. acetosella. Conclusion: Based on these findings, R. acetosella L. is a medicinal and commercially beneficial plant that warrants further investigation.
