La composition chimique de l'huile essentielle extraite des feuilles fraîches de Lantana camara Linn. récoltées sur le campus d'Abomey-Calavi (Bénin) a été étudiée par chromatographie en phase gazeuse couplée avec la spectrométrie de masse (CG et CG/SM). Quarante et un constituants, représentant 94,76 % de l'huile essentielle de Lantana camara, ont été identifiés. Les composés majoritaires sont : b-caryophyllène 18,5 % ; sabinène 13,1 % ; a-humulène 10 % ; 1,8-cinéole 9 % ; d-guaiene 5,0 %. Cette huile, testée sur des microorganismes (bactéries et champignons) et les tiques (Amblyoma variegatum), s'est révélée très efficace.

Twenty four (24) dairy ewes at the 4th stage of lactation were used to assess the milk production and serum prolactin level of ewes treated with leaf’s powder of Spondias mombin. The lactating ewes were selected and divided into 4 groups of 6 ewes per group: control group (no fed powder of Spondias mombin), Galactin group (no fed powder of Spondias mombin but treated with lactogenic drug) and groups treated with powder of Spondias mombin (group single dose and group double dose). The parameters measured include daily milk production, body weight of lambs and ewes. The resulted outcomes indicate that ewes that received powder of S. mombin and Galactin produced more milk than controls. The average daily increases in milk production were 9.92%, 14.25% and 18.88% in single dose, double dose and Galactin groups, respectively compared to control group. Lamb weight gain was also significantly higher than that in the control group. The treatments did not influence body weight of ewe. The daily weight gain of 93.12; 97.47; 99.07; 86.76 g/day were found in single dose, double dose, Galactin and control groups, respectively. The results of the blood analysis of hormone showed that serum prolactin levels increased in the group treated with powder and Galactin compared to control group.

Tomato is an important horticultural product cultivated worldwide and a major crop subject of studies. The present study therefore aims to review the state of the art of research on tomato. To do this, search was carried out in scientific databases (Science Direct, Scopus, PubMed and Agora), A suitable scientific research works were selected and analyzed. From the results, it appears that tomato is a fruit vegetable, belongs to Solanaceae family and cultivated in many countries of the world and in various climates. Its production can be done in field, but also under controlled conditions by using of artificial lighting, heaters, as well as fertigation to produce high quality tomatoes. Nutritionally, regular intake of tomato fruit increase levels of carotenoids, lycopene, vitamin C, and polyphenols compounds in the daily diet. Regarding the preservation of tomato, research papers mentioned that tomato, like any plant, is subject to agronomic constraints, such as abiotic (light, water supply, salinity, floor structure) and biotic constraints (bacterial, fungal and viruses’ attacks). Mechanical damage also influenced external quality traits of tomato. Finally, this review paper presents a brief overview of some recent studies concerning the control of tomato diseases, the valorization of tomato fruits, as well as the using of tomato waste as a bioresource for lycopene extraction. However, it would be interesting that future investigations revolve around the search for more alternatives methods to control bacterial, fungal or virus attacks, such as the use of natural compounds, in particular those from plant origin.
