Le fenugrec (Trigonella foenum-graecum L.) est une herbacée annuelle appartenant de la famille des fabacées. Il se trouve partout dans le monde, mais il est d'origine méditerranéen. Cette plante est connue par ses propriétés médicinales, thérapeutiques et nutritionnelles très importantes vu les utilisations traditionnelles et les activités pharmacologiques des composés phytochimiques présents dans les extraits des graines de cette plante (huiles essentielles, saponines et flavonoïdes…).Abstract Fenugreek (Trigonella foenum-graecumL.) is an annual herb be longing to the family Fabaceae. It is everywhere, but it is of Mediterranean origin. This plant is known for its very important medicinal, therapeutic and nutritional properties traditional uses and pharmacological activities of the phytochemicals present in the extracts made from the seeds of this plant (essential oils, saponins and flavonoids...).

Background: This work has the objective to biocontrol the bayoud disease of date palm caused by the fungus Fusarium oxysporum f. sp. albedinis (Foa), is the major disease in Algerian palm groves of south western region. This in vivo biocontrol was done on date palm variety Deglet-Nour, using two antagonistic fungi species, Trichoderma harzianum and Aspergillus flavus.Methods: Twenty Foa isolates obtained from isolation of the spines carrying the typical symptoms of Bayoud disease were used. Two strains T. harzianum and A. flavus, were isolated from rhizosphere soils of the date palm trees. Using the greenhouse screening test, which was carried out on 3-4 month-old date palm seedlings at the rate of 5 ml of inoculum suspension.Result: A statistical analysis showed a significant (P less than 0.05), difference of Deglet-Nour seedlings reactions against Foa isolates and antagonistic fungi were observed. All date palm trees present susceptibility against Foa until the total mortality of seedlings. The biocontrol test showed that two antagonists showed different reaction, with the complete resistance for seedlings treated by T. harzianum with the mortality rate (rm%) reduced at 100%, while, the second antagonist A. flavus reduced the rm% at 25%. We can apply of these antagonistic fungi to protect our groves contaminated by Bayoud disease and also contain this susceptible commercial variety.

Propolis is a resinous substance that bees use todefend their colonies against any pathogen. It has beenused in traditional medicine since ancient times because ofits therapeutic properties. Pollen analysis of propolis of AinTrid has shown that the region of Ain Trid is rich in plantspecies visited by bees (31 genus identified) and that themajority of these species are considered as medicinal plants,which gives propolis an important place in wound healing.The study of the wound healing activity is carried out in vivoon theWistar rats divided into 3 groups: group 1 treated withpropolis ointment, group 2 treated with commercial cream,and group 3 considered as untreated. The duration of treatmentwas estimated to be 23 days. The results obtainedshowed that the group treated by propolis ointment showeda high cure rate, in which the percentage of wound closurereached up to 94.93% ± 5.29 in the group 1, while in thegroup 2 arrived to 79.97% ± 13.01, and in group 3 was72.55% ± 19.94. The results demonstrated also that the numberof days required to contract 50% of wound area wasdifferent among the groups, in the 12th day in group 1,16th day in group 2, and 18th day post wounding in group 3.These results have shown that propolis can be prepared andused in traditional medicine as a natural ointment for thetreatment of skin diseases in our region.
