Iridoids are secondary metabolites with several biological activities. They are often found in species of the genus Tabebuia Gomes ex A.P. de Candolle. Tabebuia aurea (Silva Manso) Benth. & Hook. F. ex S. Moore, Bignoniaceae, is used to treat snake bites in traditional medicine. This study aimed to isolate the specioside - an the iridoid glycoside - from T. aurea, as well as investigate its potential biological properties, including anti-inflammatory, antibacterial, antibiofilm, cytotoxic, anti-Trichomonas vaginalis and antitrypanosomal activities. Specioside inhibited leucocyte recruitment into the peritoneal cavity in mice injected with carrageenan, data that demonstrated its anti-inflammatory potential. However, the additional evaluated biological properties were negligible
