Two preformed alk(en)ylresorcinols, 5-n-heptadecenylresorcinol and 5-n-pentadecylresorcinol, were identified in ‘Kensington Pride’ mango fruit peel. The alk(en)ylresorcinols had antifungal activity against C. gloeosporioides, as determined from thin layer chromatography bioassays. Soil-applied activators of plant defence (Acibenzolar at 150 mg L-1, and soluble potassium silicate at 200 and 1000 mg L-1) did not influence concentrations of 5-n-heptadecenylresorcinol or 5-n-pentadecyl¬resorcinol in mango peel when applied 2 months after fruit set and one month later. Concentrations of both alk(en)ylresorcinols were high 2 months after fruit set but levels declined by 50% within 1 month (2 months before commercial harvest) and did not change significantly from commercial harvest until eating-ripe.
