The present study appraised the inhibitory role of ethanol (PDEE) and ethyl acetate (PDEAE) extracts of Phoenix dactyliferaL. against three molecularly identified fungi: Fusarium oxysporum, Botrytis cinerea, and Rhizoctonia solani. HPLC analysis revealed that gallic acid was the major phenolic compound in both extracts: (PDEE: 1721.90 μg/g) and (PDEAE: 101.53 μg/g). The major flavonoids in PDEE are rutin, kaempferol, and quercetin, whereas PDEAE contains kaempferol, naringenin, and quercetin. The GC-MS showed 11-octadecenoic acid methyl ester (26.25%) is the highest compound in PDEE, while diisooctyl phthalate (18.82%) is the most important compound in PDEAE. At 50 μg/mL, the inhibition percentage of PDEAE initiated the highest growth inhibition of F. oxysporum(49.63%) and R. solani(71.43%). Meanwhile, PDEE at 200 μg/mL initiated an inhibition value of 77.78% for B. cinerea. As a result, PDEAE is considered more effective than PDEE in controlling the growth of selected isolates. |
