- Abstract
The ethanolic extracts of eight soft corals and five sponges were screened for antifungal activity (AU) against pathogenic fungi infected corals. The data revealed that the AUs, recorded by different crude extracts (ethanol and ethyl acetate) of soft corals, ranged between 0.0 and 49.0, which was achieved by the extract of S. gracile against A. fumigatus. In addition, the values of AUs, recorded by different crude extracts (ethanol and ethyl acetate) of sponge species, revealed that the AU ranged between 0.0 and 36.0, which was achieved by extract of Suberea mollis Row against P. auratiogriseum. Cleary, our findings proved that both ethanolic and ethyl acetate extracts of soft corals (S. polydactyla, S. gracile, S. glaucum, S. trocheliophorum, S. ehrenbergi, and X. macrospiculata) were the most effective extracts that exhibited the most potent AUs. Moreover, the most effective extracts were tested to determine the MICs against the most affected fungi and the lowest effective MIC was 10 mg/mL against several pathogenic fungi. On the other hand, the GC/MS profiles of the most effective extracts were: fatty acids and their derivatives, terpenoid (Nootkaton-11,12-epoxide, caryophyllene, geranyl-a-terpinene, etc.), steroid (corticosterone, cis-calamenene, etc.), and others. An additional trail proved the efficacy of palmitic acid (as a potent example of bioactive constituents found in crude extracts) when was compared to Treflucan.
