“…The Asparagus genus, belonging to the Asparagaceae family, includes about 300 species mainly distributed in warm temperate and subtropical regions (Negi et al, 2010). Previous investigations on some species of this genus have indicated their various pharmacological activities such as antioxidant, anti-inflammatory, antifungal, immunostimulant, antibacterial, cytotoxic and anticancer effects (Mitra et al 2012, Negi et al, 2010, and the presence of important bioactive compounds such as flavonoids, polysaccharides, steroidal saponins, ascorbic acid and minerals (Yu andFan, 2021, Fuentes Alventosa andMoreno, 2015).…”

Asparagus officinalis root (AR) contains valuable bioactive compounds that have beneficial health properties. The aim of this study was to optimize the extraction of polyphenols and flavonoids in green AR using two novel technologies; pulsed electric field (PEF) and ionic liquids (IL). Further, the antioxidant activity of the obtained extracts was determined. The total polyphenol content, total flavonoid content (TFC), and antioxidant activity (2,2-diphenyl-1-picrylhydrazyl, oxygen radical absorbance capacity and Ferric reducing/antioxidant power assays) were determined. The PEF conditions (PEF strength of 1.6 kV/ cm, frequency of 200 Hz and pulse width of 20 µs) resulted in a higher extraction yield as compared to conventional solvent extraction, but had lower antioxidant activities. The optimal conditions for IL extraction were by using 0.5% 1-butyl-3-methylimidazolium chloride at a solid: liquid (S:L) ratio of 1:10 for four min. The IL extraction resulted in a total of 122 mg RE/ mL TFC which was 70 to 80 folds more than the TFC obtained by PEF. The IL extracts had higher TFC and antioxidant activity than PEF, but the safety of the ILs need further research.

“…This savory vegetable is a plant of high nutritional and pharmaceutical values but is also often used as an ornamental plant. Asparagus is a rich source of vitamins and minerals as well as antioxidants and saponins, which occur mainly in peels [1,2]. Thanks to saponins, asparagus has antifungal, antitumor, antidiabetic and hypolipidemic properties [3][4][5][6][7][8][9].…”

Asparagus is a genus consisting of over two hundred species of perennial plants. Fusarium proliferatum is a major asparagus pathogen and it biosynthesizes a variety of mycotoxins, of which fumonisins B are prevalent. Our previous studies on F. proliferatum strains indicated that asparagus extract affects the expression of FUM1 gene, encoding polyketide synthase, a key enzyme of the FUM gene cluster governing the biosynthesis of fumonisins. An asparagus-derived F. proliferatum strain increased fumonisin B1 production after extract fractions’ addition, reaching the maximum 2 or 24 h after treatment. The cultures yielded between 40 and 520 mg of dry weight of mycelia after 14 days of cultivation. The differences in fungal biomass amounts between the whole extract and its fractions may result from synergistic effect of all bioactive compounds present in asparagus extract. Among extract fractions, the methanolic fraction had the highest effect on the dry weight of the mycelium reaching about a 13-fold increase compared to the control. Furthermore, we measured the relative expression of the FUM1 gene. Due to the possible antifungal activity of tested extract fractions, future research will be focused on the identification of the Asparagus officinalis L. compounds responsible for this activity.
