Our work was based on the study of aqueous and hydroethanol extracts from the leaves of Amaranthus hybridus L. (Amaranthaceae), Corchorus olitorius L. (Tiliaceae) and Hibiscus sabdariffa L. (Malvaceae), and decoction. This work presents for the first time the phytochemical screening and the antioxidant activity of extracts of leaves of these three plants coming from the Côte d’Ivoire. Phytochemical analysis of these extracts revealed the presence of polyphenols and alkaloids in the three leaves. The total phenolic content of the extracts showed variations, between 13.22 and 90.89 mg GAE/g. The hydroethanol extract (90.89 mg GAE/g) and decoction of C. olitorius (57.89 mg GAE/g) had the most elevated contents. The evaluation of the reducing power with DPPH method revealed that the hydroethanol extract of C. olitorius was the most active (IC50 = 45.58 µg/mL). This result was in agreement with that obtained by FRAP method.

Skin health is a concern for many people. This aim of this study is to evaluate in vitro the antioxidant activity of 10 plants used in cosmetopoeia for the maintenance of skin health. To achieve this objective, 30 extracts were tested using 2,2'-diphenyl-1-picrylhydrazyl radical (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6) acid. -sulfonic) (ABTS + •) assays. The extracts studied were rich in total polyphenols, flavonoids, gallic tannins and alkaloids. For the DPPH reduction, 7 extracts including 5 methanolic and 2 aqueous extracts showed a percentage of inhibition similar to that of Vitamin C (95.79 ± 10.53%) used as a control. With ABTS, 11 extracts (5 methanol, 3 aqueous and 3 hexane) gave reduction percentages close to Trolox (95.97 ± 8.51%). These active plants could play a role in the maintaining of skin.

This research work was carried out on the species Nephrolepis biserrata (Sw.) Schott (Nephrolepidaceae), a fern from Côte d’Ivoire with the aim of establishing its phytochemical, antioxidant and biological profile. The results obtained from the phytochemical screening show that said species contains alkaloids, coumarins, flavonoids, polyphenols, sterols, terpenes, and tannins. The antioxidant activity was evaluated spectrophotometrically against the DPPH radical in comparison with that of vitamin C. The determination of the antibacterial parameters indicates that N. biserrata doesn’t exhibit any bactericidal action against the bacterial strains tested. Regarding the vermicidal activity against earthworms, decocts of N. biserrata showed an anthelmintic effect, which however remains less pronounced than that of albendazole, the anthelmintic antiparasitic taken as a reference. Keywords: Nephrolepis biserrata, phytochemical screening, antioxidant, antibacterial, vermicide.

Aims: This work aims to compare the chemical composition and the antioxidant capacity of the leaves, stems and roots of Alchornea cordifolia. Study design: The leaves, stems and roots of Alchornea cordifolia were harvested during the month of August 2020 in the botanical garden of the University Jean Lorougnon Guede in Daloa. After that, they were dried in the shade for 17 days. Subsequently, they were crushed and kept in jars in order to be sent to the Laboratory of Industrial Processes, Synthesis, Environment and New Energies (LAPISEN) of Yamoussoukro (Côte d'Ivoire), for analyzes. Place and duration of study: This study was carried out during september to december 2020 in Laboratory of Industrial Processes, Synthesis, Environment and New Energies (LAPISEN) of Yamoussoukro (Côte d'Ivoire) Methodology: Physicochemical parameters (pH, ° Brix, MS) and the mineral contents of leave, stem and root aqueous extracts were determined by classic methods. Then, phytochemical screening are carried out by TLC analysis followed by spectrophotometric assay of total polyphenols, total flavonoids and antioxidant activity. Results: The results showed that the aqueous extract from A. cordifolia leaves, stems and roots are all acidic (pH ≤ 5.33). However, these extracts contain a low level of dry matter. The measured minerals (Na, Ca, Mg, Mn, K, Fe; Cu and Zn) are present in these extracts at varying concentrations. The leaf extract is richer in Fe (8.28 ppm), Ca (1.71 ppm), Mn (1.17 ppm) and K (0.55 ppm). In contrast, the root extract contains more Na (18.38 ppm), Cu (0.75 ppm) and Mg (0.34 ppm). As for the phytochemical screening revealed the presence of coumarins, flavonoids, sterols and terpenes, in the aqueous extract of all organs, except tannins, absent in the roots. However, the leaves have the highest content of polyphenols (256.67 mg.g-1 GAE) and flavonoids (92.75 mg.g-1 QE), as well as the best antioxidant capacity (204.23 µmol.L -1 TE). Conclusion: The leaves, stems and roots of A. cordifolia contain practically the same chemical compounds with a few exceptions. However, the difference lies in the concentration of these compounds in the different extracts.

Aims: Although the honey produced in Côte d'Ivoire is widely used in households, there is no technical sheet mentioning its chemical composition. Thus, the present study aimed to fill this gap while studying the chemical composition and antioxidant power of eleven honey samples from nine localities in Côte d'Ivoire. Methodology: The identification of secondary metabolites in the different honey samples was carried out by TLC and by color reaction tests. The quantification of these was performed by spectrophotometry. The antioxidant power of the honey samples was studied by DPPH and FRAP methods. Results: All honey samples contains secondary metabolites from various families, with varying contents of total phenolic compounds and flavonoids. Overall, the honey samples showed a notable antioxidant profile, making them good free radical scavengers. The relationship established between the different variables analyzed showed in some cases positive and significant correlations. Conclusion: The results of this study show that the honey produced in Côte d'Ivoire is of good quality. Therefore, its recurrent consumption could contribute to fighting certain pathologies caused by oxidative stress.
