酚酸含量进行了研究，从腰果叶和相关的腐殖质配置文件的NaOH和水提取物。游离和结合形式的水溶性酚酸分别进行了评价。腐殖层中的酚酸组成在很大程度上取决于叶片中的酚类物质。碱抽提物和水抽提物中均以没食子酸为主，这是因为腰果叶中水解性没食子单宁含量较高。没食子酸，原儿茶酸，对羟基苯甲酸，肉桂酸，对香豆酸和阿魏酸来自于叶子，而香草酸只发生在土壤中。总酚酸的相当大的比例是水溶性的，并通过从腐殖质层中沥滤而损失。
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.
