Abstract

Phenolic acid content was studied in NaOH- and water-extracts from cashew leaves and from the associated humus profile. Free and bound forms of water-soluble phenolic acids were evaluated separately. Phenolic acid composition in the humus layers is to a high degree determined by the phenolic substances inherited from the leaves. Alkali- and water-extracts were dominated by gallic acid, because of the high contents of hydrolisable gallotannin in cashew leaves. Gallic, protocatechuic, p-hydroxybenzoic, cinnamic, p-coumaric and ferulic acids were derived from the leaves, whereas vanillic acid only occurred in the soil. Considerable proportions of the total phenolic acids are water-soluble and lost by leaching from the humus layers.
