Accumulation of major phenolic acids in oil palm roots and their antimicrobial activity to Ganoderma boninense

Chong K. P., . and Atong M., . and Rossall S., . (2011) Accumulation of major phenolic acids in oil palm roots and their antimicrobial activity to Ganoderma boninense. [Proceedings Paper]

This paper discusses the accumulation of phenolic acids in three different varieties of oil palm and in vitro antimicrobial activity against Ganoderma boninense. The phenolic acids detected in oil palm root tissue were syringic acid SA caffeic acid CA and 4-hydroxybenzoic acid 4- HBA. The in planta accumulation were monitored for four weeks and the in vitro antimicrobial activities of the phenolics against the pathogen for eleven days. The radial growths of the pathogen on 10 PDA and on oil palm root agar OPRA ameliorated with the three phenolics with range concentration of 50-110 ug mL- were recorded daily. AVROS variety was reported to have the highest amount of the three phenolic acids compare to varieties Ekona and Calabar. SA was found to be the most active in inhibiting the pathogen followed by CA and 4-HBA. The latter was virtually inactive both in 10 PDA and OPRA. Antifungal activity of SA and CA was detected which consistent with those detected in oil palm roots.

Abstract

This paper discusses the accumulation of phenolic acids in three different varieties of oil palm and in vitro antimicrobial activity against Ganoderma boninense. The phenolic acids detected in oil palm root tissue were syringic acid SA caffeic acid CA and 4-hydroxybenzoic acid 4- HBA. The in planta accumulation were monitored for four weeks and the in vitro antimicrobial activities of the phenolics against the pathogen for eleven days. The radial growths of the pathogen on 10 PDA and on oil palm root agar OPRA ameliorated with the three phenolics with range concentration of 50-110 ug mL- were recorded daily. AVROS variety was reported to have the highest amount of the three phenolic acids compare to varieties Ekona and Calabar. SA was found to be the most active in inhibiting the pathogen followed by CA and 4-HBA. The latter was virtually inactive both in 10 PDA and OPRA. Antifungal activity of SA and CA was detected which consistent with those detected in oil palm roots.
