Replication Data for: Repellent activities against four Ascomycota species and Reticulitermes flavipes of acetonic extractives from sapwood to inner heartwood fractions of Cedrus Atlantica

The radial repartition of water/acetone extractives within the selected Atlas cedar tree (bark, sapwood, transition wood, outer heartwood and inner heartwood), at different tree height levels, were screened. HPLC analyses were performed, especially to characterized flavonoid compounds of these extractives fractions. The radial variation of the extractive composition obtained, highlighted the phenomenon of heartwood formation. Hypotheses on the metabolic pathways involved in the heartwood formation process of cedar wood were suggested, especially based on the occurrence and the radial evolution of (-)-catechin, (+)-taxifolin and flavan compounds. Then, the fungicidal and anti-termitic activities of the extracts were tested. The water/acetone extractives from the studied Cedrus atlantica showed a strong repellent activity against termites and a moderate antifungal activity against crops and fruits pathogens. Even if the sampling in this study was limited to a single tree, the results seem to bring out a potential valorisation of the extractives of the Atlas cedar, as wood preservatives and/or as biocontrol products against pathogens of ligneous agricultural crops.
