Secondary metabolites and antioxidant activity of seed extracts from Solanum elaeagnifolium Cav.

Abstract

The aim of this study was to screen various solvent extracts of seeds of Solanum elaeagnifolium to display the phytochemical composition, the total phenolic content, the total flavonoid content and the antioxidant capacity in order to find possible sources for future novel antioxidants in food and pharmaceutical formulations. Various extracts of seeds of Solanum elaeagnifolium were obtained by maceration. The total phenolic content of the different extracts was determined by Folin-Ciocalteu method, and the total flavonoid content was quantified using a method based on the formation of a flavonoid–aluminium complex .The antioxidant activity was essayed through some in vitro models such as the antioxidant capacity by phosphomolybdenum method, radical scavenging activity using 2,2-diphenyl-1-picryl hydrazyl (DPPH) assay and reducing power assay. The acetone extract showed the highest total phenolics (580.99 ± 20.56 mg gallic acid equivalents/g of extract), and the highest total flavonoids (207.61 ± 2.62 mg quercetin equivalents/g of extract). This extract showed an antioxidant activity higher than that of α-tocopherol. These results suggest the potential of Solanum elaeagnifolium against free-radical-associated oxidative damage.

Biocontrol of Fusarium Wilt and Growth Promotion of Tomato Plants Using Endophytic Bacteria Isolated from Solanum elaeagnifolium Stems

“…Several previous studies have shown that wild Solanaceae species may be useful as potential sources of bioactive molecules and biocontrol agents (Feki et al. ; Santhanam et al. ).…”

“…Although S. elaeagnifolium was considered as a potential threat to thousands of hectares of Tunisian irrigated fields in arid and semiarid regions (Mekki ), it has been identified as potent sources of secondary metabolites (Feki et al. ) and candidates for biological control (Cuda et al. ).…”

“…Wild plants are better suited to tolerate difficult soil conditions including abiotic as well as biotic stress. Several previous studies have shown that wild Solanaceae species may be useful as potential sources of bioactive molecules and biocontrol agents (Feki et al 2014;Santhanam et al 2014). A wild Solanaceae, S. elaeagnifolium, was used in this study for isolation of endophytic bacteria exhibiting eventual antifungal activity towards FOL.…”

Although S. elaeagnifolium was considered as a potential threat to thousands of hectares of Tunisian irrigated fields in arid and semiarid regions (Mekki 2006), it has been identified as potent sources of secondary metabolites (Feki et al 2014) and candidates for biological control (Cuda et al 2002). Previous studies have identified other potential uses for S. elaeagnifolium where their aqueous and organic extracts have shown molluscicidal, nematicidal and insecticidal activities (Ben Hamouda et al 2015).…”

Total Polyphenols Content, Antioxidant and Antimicrobial Activities of Leaves of Solanum elaeagnifolium Cav. from Morocco

“…The extraction yield of S. elaeagnifolium depended on the extraction solvents and the plant part. Feki et al [36] collected the S. elaeagnifolium plant (for seed study) in December 2011 (final maturity stage) in Monastir. They found the methanol extract of S. elaeagnifolium seeds presented the highest yields at 7.7%, followed by the acetone extract at 5.31%.…”
