Exploration of the Chemical Potential and Antioxidant Activity of Some Plants Used in the Treatment of Male Infertility in Southern Benin

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

Dominant bacterial diseases in the extensive and semi-intensive animal breeding and their treatment method by ethnoveterinary medicine in Benin.

In Africa, various medicines are used in animal diseases treatment. This study aims to identify the medicinal plants that are often used to cure bacterial diseases in domestic animals, in order to promote their rational and sustainable use. The work was performed by working with 787 breeders in the 8 agro-ecological zones of Benin, from June to December 2013. An ethnobotanical survey has identified 32 medicinal plants species among which Afzelia africana, Crossopteryx febrifuga, Albizia chevalieri, Khaya senegalensis, Mangifera indica and Entada africana are used for bovine pasteurellosis. The bronchitis is treated by 11 species of medicinal plants which include Allium sativum, Garcinia kola, Terminalia laxiflora, Zanthoxylum zanthoxyloides and Detarium microcarpum. For infectious coryza treatment, 8 plants have been identified among which, we have Securinega virosa, Capsicum annuum, Anacardium occidentale and Vitellaria paradoxa. About cutaneous streptothricosis, 3 plants (Zea mays, Piliostigma thonningii and Parkia biglobosa) were cited for its treatment. Contagious bovine peripneumonia is treated by 3 plants (Tamarindus indica, Oxythenanthera abyssinica and Khaya senegalensis). Avian salmonellosis is also treated by 3 plants (Bridelia ferruginea, Cissus quadrangularis and Ocimum gratissimum). Concerning Blackleg and enterotoxemia, they are respectively treated by Aganope stulhmannii and Ocimum gratissimum.
