“…In fact, the antibacterial activity of plant extracts is closely associated with the extraction procedure. Depending on the type of solvent used, various compounds with different polarities and concentrations are obtained at the end of the process [ 44 ].…”

Bioactive properties of faveleira (Cnidoscolus quercifolius) seeds, oil and press cake obtained during oilseed processing

et al. 2017

To the best of our knowledge, this is the first report in the literature concerning the bioactive properties of faveleira products. This work focuses on the physicochemical evaluation of faveleira oil, as well as it investigates the bioactive properties of faveleira seeds, faveleira oil and the press cake obtained during the oilseed processing. The seeds were cold pressed and the following tests were performed: physicochemical characteristics (acidity, peroxide values, moisture and volatile matter, density and viscosity) and fatty acid profile of faveleira oil; total phenolic and flavonoid content of faveleira seed and press cake; antibacterial activity of seed, oil and press cake; and antioxidant activity (DPPH radical scavenging activity, reducing power assay, total antioxidant capacity, superoxide radical scavenging assay and oxygen radical absorbance capacity) of seed, oil and press cake. Our work demonstrated that the faveleira seed oil has low acidity (0.78 ± 0.03% oleic acid) and peroxide value (1.13 ± 0.12 mEq/1000g), associated with the relevant concentration of linoleic acid (53.56%). It was observed that important phenolics (398.89 ± 6.34 mg EAG/100 g), especially flavonoids (29.81 ± 0.71 mg RE/g) remain in the press cake, which indicates that the by-product of the faveleira oilseed production constitutes a rich residual source of bioactive compounds. No bacterial growth inhibition was detected, but all samples including faveleira seeds, press cake, oil and its fractions have potent antioxidant activities, mainly the press cake, with oxygen radical absorbance capacity of 28.39 ± 4.36 μM TE/g. Our results also show that faveleira oil has potential to be used as edible oil and the press cake should be used to contain the most antioxidants from seed.

“…found that the seed extracts of the Anisophyllea laurina R. Br. ex Sabine fruit revealed the highest activity in the ethanol solvent; followed by methanol, ethyl acetate, and water, respectively [31]. This was true for all three types of assays that involved the FRAP, DPPH, and ABTS assays.…”

In this study, the Maprang ( Bouea macrophylla Griffith) seeds of 3 Thai varieties of this plant were studied in terms of nutrition, phytochemicals, chemical antioxidants and the bioactivity of their extracts. Maprang seeds revealed high levels of carbohydrates, dietary fiber, energy, potassium, phosphorus, magnesium, and calcium. The Maprang seed extracts possessed a high polyphenolic content and exhibited antioxidant properties against DPPH˙, ABTS˙ + , and ferric reduction. Additionally, 18-compounds were charaterized by RP-HPLC-DAD with two being recognized as gallic acid and ellagic acid and 16-unknown gallotannins. The HPLC fingerprint was composed of 4 major compounds. The extract showed active growth inhibition against leukemia, lung cancer cell lines and for 15 strains of bacteria. It is known to be particularly effective in drug resistant cells. Our results indicated that maprang seeds are a new natural source of nutrition, minerals and phytochemicals that may be applicable for use as a food supplement and as an effective drug in the treatment of certain diseases.

“…Despite of this research studies to unveil the pharmacological importance of V. thapsus, the true gigantic antibacterial potency of this plant still remains hidden. The antibacterial and other biological activity of the extract depend on the extraction solvent and mode of extraction , Onivogui et al 2016. The increasing polarity order of the solvents based extraction from the leaves of V. thapsus was used for the first time in the present study.…”

Antimicrobial effects of Verbascum thapsus L. leaf extracts

et al. 2020

Antimicrobial activity of leaves of Verbascum thapsus L. using different extractions solvents was evaluated. Extracts were prepared and tested against different bacterial (Pseudomonas aeruginosa, Klebsiella pneumoniae, Bacillus atrophaeus, Salmonella typhi, Citrobacter freundii and fungal species (Alternaria solani, Candida albicans, Aspergillus fumigatus). Disc and well diffusion assays were used for screening antibacterial and antifungal potential of extracts. The ethyl acetate extract produced the maximum zone of inhibition (70% ZI) against K. pneumoniae at 3000 μg/disc. Methanol extracts formed 68% ZI against S. typhi, 54% ZI against A. tumefacian and 50% ZI against C. freundii, respectively at 3000 μg/disc respectively. Against the fungal species, the methanol extract was effective and formed maximum zone of inhibition (50% ZI) against A. solani at 3000 μg/well. Hexane extract was moderately active against bacterial species but inactive against tested fungal species. T. rubrum was resistant and none of the tested extracts affected its growth.
