Phytochemical and Antimicrobial Properties of Oil Extracts from the Seeds of Ricinodendron heudelotii

Objectives: Dacryodes edulis is a versatile plant in many African countries, as its various parts are employed to treat several diseases. Like most plants used in traditional medicine, the possible mechanism by which D. edulis functions is still unknown. This study was designed to investigate the components of the plant seed with a view of justifying its use as traditional medicine. Methods: The seed oil of D. edulis was exhaustively extracted with a Soxhlet extractor from 500 g seeds and 200 g seeds of D. edulis using ethanol and petroleum ether as solvent, respectively. The extraction solvent was removed to obtain the oil which was then subjected to antimicrobial activity test to determine its activity against the following clinical isolates namely Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus cereus, and Escherichia coli using gentamycin as positive control. Phytochemical screening and gas chromatography-mass spectrometry (GC-MS) analyses were carried out following standard methods Results: Ethanolic extract resulted in a higher percentage of oil yield (11.6%) than petroleum ether (5.3%). D. edulis seed oil showed remarkable activity against Gram-negative and Gram-positive isolates: E. coli, Bacillus spp, and S. aureus but not against P. aeruginosa. The presence of saponins, quinones, cardiac glycosides, terpenoids, and phenol was confirmed during qualitative phytochemical screening, and the preliminary results from GC-MS analysis show the presence of terpinen-4-ol, 4,6,6-trimethyl bicyclo[3.1.1]hept-3-en-2-one, ethyl 14-methyl-hexadecanoate, methyl 19-methyl-eicosanoate, squalene, C-14 to C-18 fatty acids, and their esters. Conclusion: The study, therefore, confirms that the use of D. edulis as component of traditional medicine may be justified.

The effect of three African medicinal herbs used as feed additive on the growth and survival of Nile tilapia (Oreochromis niloticus) was studied. Four isoproteins (32%) and isolipid (13%) diets, namely RC (control diet or 0% plant), 3% B. vulgaris, 3% K. africana and 3% R. heudelotti, were manufactured. One hundred and eighty (180) Nile tilapia fry with an initial average weight of 0.15 ± 0.01 g were randomly distributed in 12 plastic tanks (50 L / tank) at a density of 15 fish per tank and fed three times (8.00 h am, 1.00 h pm and 5.00 h pm) per day for 90 days. For the parameters studied (average weight gain (AWG), feed conversion ratio (FCR), specific growth rate (SGR) and survival rate (SR)) no significant difference was observed between diets at the end of the experiment. Furthermore, the addition of 3% K. africana or B. vulgaris or R. heudelotti had no impact on the dry matter, ash, crude protein and whole-body fat content of Nile tilapia fry. This study showed that 3% B. vulgaris or K. africana or R. heudelotti has no adverse effect on the growth, survival and whole-body composition of Nile tilapia fry.

Ricinodendron heudelotii, Vitex doniana, and Cleome gynandra are three indigenous species of Benin/West Africa. This review focuses on the physicochemical characteristics of their seeds and the nutritional and functional properties of their oils. In this systematic review, scientific articles and reports were used to collect information. The minima, maxima, and mean values were considered and converted into a dry basis and/or the same units by using the international system of units when needed to allow comparison. Seeds of Ricinodendron, Vitex and Cleome fat contents were 51.83 g/100 g dw, 28.55 g/100 g dw and 27.35 g/100 g dw, respectively. The three seed oils contained 58.54% to 87% mono and polyunsaturated fatty acids. Ricinodendron seed oil contained a conjugated polyunsaturated fatty acid α‐eleostearic acid (49.3%–51.1%). Data varied from one author to another due to the methods used. R. heudelotii seeds oil is traditionally used for the treatment of several diseases. Its oil showed phytochemical and antimicrobial properties suggesting its possible use in pharmaceutical industries. Ricinodendron and Vitex seed oil should not be used for cooking at high temperatures or frying because of their high and medium levels of unsaturation.
