The phytochemical studies of Eschweilera longipes have led to the identification of ten triterpenoids: fridelin, fridelinol, alpha-amirin, beta-amirin, 3beta-O-cinamoyl-alpha-amirin, 3beta-O-cinamoyl-beta-amirin, alpha-amirenone, beta-amirenone, 3-alpha-hidroxi-lupeol, 3-alpha-hidroxi-taraxasterol, along with b-sitosterol, stigmasterol, alpha -tocopherol and tocotrienol. The structures of these compounds were identified by analysis of IR, ¹H and 13C NMR data and comparison with values of literature.
