“…This suggests that, the methanol, acetone, ethyl acetate and water extracts of B. monosperma bark must be considered as good source of phenolic compounds. However, a very high amount of phenolic content (>775 mg GAE/g extracts) was reported in Acacia auriculiformis (Singh et al 2007). This tremendous increase in phenolic content could be explained due to further fractionation of the crude extracts used in their study.…”

“…The antioxidant potential of extracts displayed by deoxyribose degradation (site-specific and nonsite-specific) assay was found to be highly correlated to their total phenolic content, showing a positive correlation in most of the extracts. The abilities of extracts in both the assays indicate their effectiveness as chelating agents, as well as their capacity to scavenge OH• radicals which are produced in solution from a Fe 2+ -EDTA chelate (Singh et al 2007).…”

The antioxidant activity, phenolic contents and phytochemical profile of acetone, methanol, water and ethyl acetate extracts of the stem bark of B. monosperma were investigated. Extracts showed highest antioxidant activity at 100 μg ml −1 with application of different assays: 2 -2 diphenyl-2 picrylhydrazyl (DPPH) scavenging (83.5% and 78.1%), reducing power (1.85 and 1.78), deoxyribose degradation site-specific (65.5% and 61.5%) and non-site-specific (67.1% and 66.5%) and chelating power (63.4% and 58.9%) in decreasing and increasing polarity of acetone extracts, respectively. However, nitroblue tetrazolium (NBT) showed scavenging of O 2 • radicals by 56.4% and 53.1% in decreasing and increasing polarity methanol extracts, respectively. Similarly, electron paramagnetic resonance (EPR)/spin-trapping exhibited highest radical scavenging activity with acetone extracts (12.6 mg g −1 Trolox). The results pointed to the significant antioxidant activities in acetone and methanol extracts. In most cases, the extracts obtained through decreasing polarity showed higher antioxidant activity. The phenolic content exhibited a strong association (r 2 > 0.9) with antioxidant activity. These results suggest that bark of B. monosperma can be a potential source of natural antioxidants.

Abstract. The present study investigates the antioxidant and antibacterial activities of the essential oils obtained by hydrodistillation of the pulp and the seeds of Ceratonia siliqua. Dried pods (pulp or seeds) were subject to the hydrodistillation for 3 h using a Clevenger-type apparatus. The two essential oils obtained were characterized by its physicochemical indications. Theses oils were used for the determination of the antioxidant activity by free radical scavenging activity, reducing power and liver lipid peroxidation methods and for the evaluation of the antibacterial properties against referenced tested bacteria. The oil of the pulp presents a high scavenging power of free DPPH radical 89.0 ± 1.2 % at concentration 1000 µg/mL and IC50 7.8 µg/mL compared to the seeds 79.0 ± 1.6 %, IC50 31.25 µg/mL. A significant activity for reducing iron and protection against lipid peroxidation induced by Fe +2 were obtained by the oil of the pulp. The essential oils of carob showed a good antibacterial activity against tested referenced pathogenic bacteria Staphylococcus aureus ATCC 25923, Pseudomonas aerugenosa ATCC 25853 and Escerichia coli ATCC 25922.
