“…This difference in results may be due to the part of the plant used. The results obtained in this study suggested that the aqueous extract concentrates the most chemical constituent and has the ability to donate hydrogen to a free radical 17 . The presence of phtytocompounds, in this case, the flavonoids observed in this work, would justify the antioxidant activity of the aqueous extract which would be due to its richness in phenolic compounds.…”

Background and Objective: Nowadays, research on medicinal plants has intensified due to the diverse therapeutic potential of medicinal plants. The aim of this work is not only to go through the ethnobotanical knowledge of Sarcocephalus latifolius in Southern Benin but also to evaluate the antioxidant potential and toxicity of S. latifolius root extracts. Materials and Methods: Thus, an ethnobotanical survey was carried out in 06 markets located in Southern Benin. The antioxidant activity of S. latifolius root extracts was performed using the Ferric Reducing Antioxidant Power (FRAP) assay. To end, toxicity was performed on Artemia salina larvae following the dilution method. Results: The antioxidant activity revealed that the aqueous extract with IC 50 of 0.299 mg mLG 1 has better antioxidant activity than the ethanolic extract (LC 50 = 0.37 mg mLG 1 ). Larval toxicity shows that aqueous extract (LC 50 = 0.528 mg mLG 1 ) and ethanolic extract (LC 50 = 3.62 mg mLG 1 ) show no toxicity. Conclusion: The data of this study indicate that the extracts of S. latifolius present antioxidant and antimicrobial properties and do not present toxicity. This may justify its traditional use in the treatment of microbial infections.

The cashew tree, a tree adapted to tropical areas was introduced in Africa by European explorers. Its cultivation in some African countries has been done to stop the advancing Sahara desert and to reduce soil erosion. The cashew fruit consists of a nut being the real fruit, and a fleshy apple which is considered the pseudo-fruit. The nut represents the major point of interest in cashew tree cultivation. Despite being a commodity of international trade, cashew apple suffers from low commercial interest. As a result, millions of tons of cashew apple rot in orchards without any form of processing every year. Gradually, its excellent properties are attracting the attention of the scientific world and industrialists with a view to enhancing its commercial and food value. This review reports different methodologies of transforming cashew apple. Some potential products include juice and potential cocktails. Juice clarified by tangential microfiltration was almost cleared of tannins, giving good clarity and a pleasant taste. A stabilized cocktail of cashew apple and pineapple juices using 10% ginger aqueous extract was judged good as it retained prime quality for 7 days at 4 - 5 °C, with significant improvement of vitamin C and protein content (p ≤ 0.05). Obtaining an amber dry wine of 12.6% alcohol with no significant difference (p < 0.05) from commercial grape wine was demonstrated using Saccharomyces cerevisiae as a fermenting agent. Ethanol of 97.8% purity was also obtained by immobilized cells of S. cerevisiae on silica gel. Edible vinegar of 4% acidity with similar characteristics as commercial varieties was produced from the juice. Jam and a viscous syrup of 80 °Brix which was found to be rich in glucose and fructose was also produced. A generator powered by 6% cashew apple biofuel with the rest being gasoline revealed reduced fuel consumption compared to the use of gasoline alone, though engine behavior during its operation was a concern. Also, cashew apple flour has been used for the manufacture of composite biscuit formulated with or without wheat flour. Thus, cashew apple could become a source of additional incomes for peasants by being the origin of creation of companies through these various developed technologies. Key words: cashew apple, processing, juice, alcohol, vinegar, jam, syrup, flour, biofuel

Antioxidants are a family of substances that can neutralize free radicals and prevent and/or treat diseases associated with oxidative stress such as male’s infertility. Medicinal plants are one of the main sources of antioxidants. Aim: This work was aimed at evaluating the chemical and antioxidant potential of different extracts from some plants used in traditional Beninese medicine for the treatment of male infertility. Materials and Methods: The study was carried out on aqueous, hydro-ethanolic and ethanolic extracts from of the roots of Gardenia ternifolia (G. ternifolia), the whole plant of Cassytha filiformis (C. filiformis), the leaves of Rourea coccinea (R. coccinea) and the seed of Garcinia kola (G .kola). Quantification of the total polyphenols and flavonoids content of these extracts was evaluated respectively by the method using Folin Ciocalteu and the method using Aluminum trichloride. The antioxidant activity of the extracts was evaluated by molecular spectrophotometry using the free radical scavenging of DPPH and FRAP methods. Results: The results obtained indicated a variation of total polyphenols and flavonoids content according to the type of extract. Hydro-ethanolic extract of the various plants studied has a high polyphenols and flavonoids content. In variable proportions, all the extracts tested reduced the DPPH radical and ferric iron, reflecting their antioxidant potential. The best antioxidant activity has been obtained with the hydro-ethanolic extracts. Conclusion: This study showed that all the plant's extracts studied have antioxidant activity that varies with the type of extract. However, the hydro-ethanolic extractions showed the best antioxidant activities. The data obtained in the present study justified the use of these plants in management of pathologies involving oxidative stress.
