To understand the influence of environmental factors on the metabolic diversity of phytochemical compounds from extracts of leaves and bark of Anacardium occidentale, collected in two different geographic areas, ultra-performance liquid chromatography and mass spectrometry were used, as well as the composition of physicochemical properties of both soils at the collection site (“Lavras da Mangabeira” and “Crato”). It was possible to observe physicochemical differences between the soils of the two collection areas and some similarities. Both present granulometry with a sandy texture, with high values of total sand, with acid pH, and variation in porosity rates. The micronutrients with the highest accumulation in the soil, with emphasis on the predominance of P (Phosphorus) and Al (Aluminium) mainly in the 20–40 cm layer in Crato. Thirty-three phytochemical compounds were identified in the leaf and bark extracts, of which 28 were present in the leaves and 20 in the bark part. Of this total, 13 were present in at least one of the parts of the plant (leaf or bark), and most were present in both Crato and Lavras da Mangabeira, presenting mainly phenolic acids, flavonoids and tannins in all extracts evaluated. Both extracts showed similarities between the groups of compounds. Taken together, this study may be relevant to assess environmental influences on the production of secondary metabolites.
