Phytochemical Composition and Antioxidant Activity of Balanites aegyptiaca, Securidaca longepedunculata and Acacia gourmaensis Used against Seed-borne Fungi in Burkina Faso

Abstract

Aims: Hydroethanolic extracts of Balanites aegyptiaca, Securidaca longepedunculata and Acacia gourmaensis from Burkina Faso were investigated for their phytochemical composition and their antioxidant activities. Methods: Highperformance thinlayer chromatography (HPTLC) method was used for phytochemical screening. The total phenolic, total flavonoid and anthocyanin contents of extracts CJAST, 39(1): 79-87, 2020; Article no.CJAST.54710 80 were assessed. The antioxidant potentials of the extracts were also evaluated using 2,2diphenyl lpicrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP). Results: Phenolic compounds, flavonoids and anthocyanins were present in all these plant extracts. Tannins were only found in Acacia gourmaensis extract. Acacia gourmaensis extract exhibited the highest total phenolics (807.58 ± 28.63 mg GAE/g), total flavonoids (271.39 ± 58.46 mg QE/100 g), total anthocyanins (83.16 ± 0.14 µg/g) contents and had the highest antioxidant activity by DPPH ( 330.84 ± 16.23 µg AAE/g) and FRAP methods (3211.11 ± 52.24 µg AAE/g ). Balanites aegyptiaca and Securidaca longepedunculata showed the lowest phenolic compounds (80.72 ± 2.11 mg GAE/g and 76.69±1.84 mg GAE/g respectively); total flavonoids (88.7 ± 1.65 mg QE/100 g and 104.54 ± 9.65 mg QE/100 g respectively), anthocyanins (24.49±1.43 µg/g and 24.57±0.52 µg/g respectively) contents and had the lowest antioxidant activity for DPPH method ( 46.83 ± 3.01 and 56.20 ± 3.79 µg AAE/g respectively) and FRAP method ( 102.06 ± 5.09 and 57.78 ± 0.99 µg AAE/g respectively). Conclusion: Balanites aegyptiaca, Securidaca longepedunculata and Acacia gourmaensis represent natural sources of phenolic antioxidant compounds that can be used as a biofungicide.

Phenolics from Medicinal and Aromatic Plants: Characterisation and Potential as Biostimulants and Bioprotectants

“…These tests include the 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and Trolox Equivalent Antioxidant Capacity (TEAC) assays, among others. Several studies have shown a positive correlation between the measured antioxidant activity and the phenolic content [61,75,76]. However, since the test is dependent on the phenolic content, values of the antioxidant activity are also dependent on the extraction solvent, extraction time, extraction method as well as the other factors cited earlier that affect the phenolic content determined from a given plant sample [61].…”

Acaricidal activity of three plants extracts from the central region of Burkina Faso on adult <I>Rhipicephalus (Boophilus) microplus</I> cattle ticks

“…Each raw extract was subjected to phytochemical screening. Tannins, flavonoids, alkaloids, saponins, and triterpenes were searched for on the various extracts using standard procedures as described in the literature (Wagner and Bladt., 1996;Békro et al, 2007;Ramde-Tiendrebeogo et al, 2019;Nitiema et al, 2020).…”

“…Similarly, other studies have shown the effectiveness of plant extracts on this tick in Benin (Adehan et al, 2016), in Brazil (Silva et al, 2017;Politi et al, 2019) in India ( Kumar et al, 2012) in New Caledonia (Lebouvier et al, 2013). To find new sources of natural acaricides, we were interested in three aromatic plants from Burkina Faso (Ocimum gratissimum, Ocimum americanum, and Laggera oloptera) whose biological activities have been reported in numerous works including their insecticidal properties (Nébié, 2006;Ouédraogo et al, 2016;Tia et al, 2019). The present study, therefore, aimed at assessing the acaricide efficacy of the extracts of these three plants on adults of the tick R. (B.…”
