Bentrad, N., Gaceb-Terrak, R., Benmalek, Y., & Rahmania, F. (2017). STUDIES ON CHEMICAL COMPOSITION AND ANTIMICROBIAL ACTIVITIES OF BIOACTIVE MOLECULES FROM DATE PALM (PHOENIX DACTYLIFERA L.) POLLENS AND SEEDS. African Journal of Traditional, Complementary and Alternative Medicines, 14(3), 242-256. https://doi.org/10.21010/ajtcam.v14i3.26
traditions as alternative medicines. The chemical profiling of some plant extracts and essential oils related to different
plants were followed to unveil their most active components. In this paper, Phoenix dactilyfera L was selected as a host
plant to investigate the composition of different organs with different cultivars.
Materials and method: The antibacterial and antifungal activities of the extracts have been tested using different
techniques, including optical density and GC/MS analyses of the natural extracts.
Results: GC/MS analysis revealed the presence of abundant oleic (36.69%) and lauric (20.49%) acids in date seeds.
However,the pollen contains a high amount of palmitic (22.27 %), linoleic (33.4%) and linolenic (17.055%) acids.
Moreover, the largest inhibition zone is obtained with the organic extract of Deglet Nour which showed a strong
antibacterial activity against Escherichia coli and pollen extract showed also a strong inhibition against Escherichia
coli, Staphylococcus aureus, S. aureus MRSA and Enterococcus faecalis. Aqueous extracts of date palm seeds of and
pollen seem to have a fongitoxique activity from a concentration of 6 mg.mL-1 and 12mg.mL-1 of cyanidine; as well as
the organic extracts of pollen with a concentration of 90 μg.mL-1 induce an inhibition to the growth of five special
forms of Fusarium oxysporum.
Conclusion: The bioactive compounds of date palm can be used for drug development and in the food industry.
