The present work studies the antioxidant activities and antimicrobial properties of the aerial part of Retama sphaerocarpa. The secondary metabolites (polyphenols) were extracted using different solvents: chloroform, ethyl acetate and n-butanol. In each fraction, total polyphenols and flavonoids were respectively quantified using Folin-Ciocalteu test and aluminium chloride colorimetric method. The concentration of polyphenols was higher in the chloroform extract (121.4 +/- 0.3 mg GAE/g), than in n-butanol extract (111.7 +/- 0.1 mg GAE/g) and ethyl acetate extract (73.0 +/- 0.4 mgGAE/g). The evaluation of flavonoids content also showed a high value of flavonoid in chloroform extract (20.9 +/- 0.2 mg QE /g DM), whereas the ethyl acetate and the n-butanol extracts of Retama sphaerocarpa leaves contained similar quantity of flavonoids with 16.5+/- 0.8 mg QE /g DM and 15.3+/- 0.7 mg QE/g DM, respectively. The obtained extracts of R. sphaerocarpa were also evaluated for their antioxidant activities using DPPH radical-scavenging method. The three extracts (i. e. chloroform, ethyl acetate and n-butanol extracts) showed very high free radical scavenging activity: 73 +/- 0.8, 75.6 +/- 1.9 and 81.5 +/- 0.3 (\%), respectively. We also investigated the antimicrobial activities of the three extracts using the disc diffusion method. Each of the three extracts were active against Bacillus sp.

The effects of growing stage (immature and mature) and home cooking methods (boiling and steam cooking) on the phytochemical contents, and antioxidant capacity of faba bean were investigated. Different faba bean morphological fractions (whole pod, pod coat, whole seed, seed coat and cotyledon) were analyzed. The antioxidant capacity was evaluated by the DPPH radical scavenging capacity, total antioxidant capacity, and oxygen uptake inhibition. The results showed that the immature faba bean fractions had significantly higher phytochemical contents and displayed a better antioxidant activity than those of mature ones; the highest level of phytochemicals and the strongest antioxidant activity were recorded in the seed coat. This study demonstrates also that cooking caused significant decrease in the phytochemical bioactive contents, and antioxidant activity, depending on the morphological fraction and cooking practice. The results of this study revealed also that steam cooking would be preferred to preserve the bioactive phytochemicals of faba bean.

Content and type of extractives vary considerably among woody species in the Congo Basin tropical forest. They influence the natural durability of wood with respect to fungal and insect degradation. Species containing higher amounts of extractives and Klason lignin were generally less susceptible to fungal colonization. Phenolic extractives with large anti-fungal and high antioxidant activities were the main chemical family of compounds extracted from the tested species, which suggests a potential chemical valorization of these extractives.

Several woody species from the Congo Basin are known for their natural durability, but the causes of this natural durability are not always fully elucidated. This is particularly the case for the resistance to white rotting fungi decay.

The chemical composition as well as the antioxidant activity of the heartwood extractives of several species were quantified and correlated to the ability of different fungi to colonize wood sawdusts in order to better understand their decay resistance.

The chemical screening of extracts was conducted using colorimetric methods. The quantity of lignin, extracts and total phenolic compounds, as well as antioxidant activities were determined. Extracted and unextracted heartwood sawdusts were exposed to two white rot fungi to assess the effect of extractives on their colonization.

Extractives and lignin contents ranged from 2.7 to 16.0 \% and from 26.5 to 35.9 \%, respectively. Antioxidant activity was directly connected to total phenolic contents. The phytochemical screening revealed the presence of different chemical groups in all extracts. Resistance to fungi was correlated to the amount of extractives and in most cases to the lignin content.

Phenolic compounds associated with antioxidant activities influenced the natural resistance of heartwood.
