Phenolic profiling and in vitro bioactivity of Moringa oleifera leaves as affected by different extraction solvents

Toplam 122 atıf DOI
In this work the (poly)-phenolic profile of Moringa oleifera leaves was comprehensively investigated through untargeted metabolomics, following a homogenizer-assisted extraction (HAE) using three solvent systems, i.e. methanol (HAE-1), methanol-water 50:50 v/v (HAE-2) and ethyl acetate (HAE-3). This approach allowed to putatively annotate 291 compounds, recording mainly flavonoids and phenolic acids. Thereafter, antioxidant capacity, antimicrobial activity and enzyme inhibition were assayed in the different extracts. HAE-1 extract showed the highest total phenolic content (31.84 mg/g), followed by HAE-2 (26.95 mg/g) and HAE-3 (14.71 mg/g). In addition, HAE-1 and HAE-2 extracts exhibited an expressive activity against Bacillus cereus and Listeria innocua. The HAE-2 leaf extract was characterized by the highest DPPH and ABTS values (being 49.55 and 45.26 mgTE/g), while ferric reducing antioxidant power was found to be higher in HAE-1 (58.26 mgTE/g). Finally, the enzyme inhibitory effects of M. oleifera leaf extracts were investigated against five enzymes, namely acetylcholinesterase (AChE), butyrylcholinesterase (BChE), tyrosinase, α-amylase and α-glucosidase. All of the tested extracts exhibited inhibitory effects on AChE and BChE with a higher activity for HAE-3 and HAE-1, whilst HAE-1 showed the higher impact on tyrosinase, glucosidase and amylase activities. Taken together, these findings suggest that M. oleifera leaf extracts are a good source of bioactive polyphenols with a potential use in food and pharma industries.

Solanum erianthum D. Don. and S. torvum Swartz of the family Solanaceae have been extensively used for both food and pharmaceutical purposes. In this study, a metabolomic approach was used to compare the phytochemical composition and biological activity of the different plant parts of both species. The inhibitory activity against important enzymes (i.e., cholinesterases, tyrosinase, α-amylase and α-glucosidase), antimicrobial and antifungal potentials, in vitro antioxidant activity, as well as the phenolic and alkaloid profiles of the fruit, leaf and stem bark extracts of both species were studied. The results showed that the stem barks were characterized by the highest amounts of total phenolics (on average: 12.6 mg/g), whilst the S. erianthum leaves were the best source of total alkaloids (2.1 mg/g). Overall, the stem bark extracts of both species were found to be a good source of antioxidant compounds. All the extracts were effective against acetylcholinesterase and tyrosinase, while only the leaf extracts of both plants were a good source of butyrylcholinesterase inhibitors. The extracts have significant anti-microbial and anti-fungal potentials. A modest anti-diabetic effect was measured for α-amylase and α-glucosidase. Strong correlations (p <0.01) were found between the bioactives and the biological activities. Therefore, this study showed the potential of untargeted metabolomics to investigate the bioactive profile of plant extracts, thus providing discrimination between S. erianthum and S. torvum.
