Antifungal activity ofParastrephia quadrangularis(Meyen) Cabrera extracts againstFusarium verticillioides

Abstract

In Argentina, Fusarium verticillioides causes 'ear rot', a disease that produces important yield and nutritional quality losses in the maize producing region. This study suggests that Parastrephia quadrangularis extracts have potential for the growth inhibition against F. verticillioides M7075, and the bioactivity is reported for the first time. The results obtained will provide a starting point for discover new antimicotic candidate in natural products.

Antioxidant activity of nine medicinal plants with commercial potential

“…Most of these species are used by the native of the high Andes to relieve among other uses toothache, fractures, and bruises of bones . For many of these species have been reported multiple biological activities found in alcoholic extracts, such as anti-inflammatory activity, antioxidant, antibacterial, as well as the antifungal activity (Di Ciaccio et al, 2018;Echiburu-Chau et al, 2017;Zampini et al, 2009). In the last decade, studies on antioxidant activities of medicinal plants have increased remarkably due to increased interest of the healthy food industry in their potential of being used as a rich and natural source of antioxidants (Gonçalves et al, 2013;Li et al, 2013).…”

Gastroprotective Activity of Parastrephia quadrangularis (Meyen), Cabrera from the Atacama Desert

“…Regarding the phytochemical components of P. quadrangularis , a poly-methylated flavonoid: 5,7- dihydroxy-3,8,3′,4′-tetramethoxyflavone, some common coumarins and tremetones were reported [ 12 , 15 ]. Recently, other tentative molecules (coumaroyloxytremetone- O -hexoside and coumaroyloxytremetone C -hexoside) found in a sample from Argentina were suggested using only low-resolution mass spectrometry [ 16 ]. Some extracts of this species showed antifungal properties against Fusarium verticilloides which were attributed to the presence of tremetones in the active fractions of the plant [ 16 ].…”

On the other hand, medicinal tinctures are extracts of the active metabolites of the most usable part of a medicinal plant; For this, an extraction method is used in which the plants are submerged or macerated for days in mixtures of edible ethanol water or edible pure ethanol [ 17 , 18 ].…”
