Biochemical components, enzyme inhibitory, antioxidant and antimicrobial activities in endemic plantScilla mesopotamica speta

In this study, in vitro antioxidant, antimicrobial, anticholinesterase and phenolic profile of different solvent extracts of Scilla mesopotamica speta were determined in detail. In vitro antioxidant activities and total phenolic and flavonoid contents of plant extracts obtained with different solvents were tested in terms of 2.2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activities. The highest total phenolic and total flavonoid contents were determined in the ethyl acetate extract (62.24 µg GAE/mg) and chloroform extract (87.72 µg QE/mg) respectively. The highest DPPH radical scavenging activity was detected in ethyl acetate extracts. Antimicrobial and antifungal activities were investigated by MIC method. The inhibitory activities of the extracts on the acetyl cholinesterase enzyme were investigated. Liquid chromatography (LC) tandem mass spectrometry LC-MS/MS was used to determine the phenolic component content of extracts. Thirty-one different components were identified in the analyses and their amounts were measured. Practical applications Scilla mesopotamica speta is an endemic and medicinal plant. It was determined that the extracts of this plant had a very rich content in terms of phenolic compounds, especially caffeic and ferulic acids. However, this plant was remarkable for its antioxidant, anticholinesterase, and antimicrobial activities. Considering the strong antioxidant, antimicrobial, and enzyme inhibition activities of the Scilla mesopotamica speta it can be suggested as a source of anticancer, antimicrobial, and antiviral drugs.
