Description	Endogenous cytokinins (CKs), auxins, and abscisic acid (ABA) were identified and quantified in 11 red algae collected from the Brazilian coast. Seaweed materials were extracted, purified by solid-phase extraction followed by immunoaffinity chromatography, and analyzed by liquid chromatography-tandem mass spectrometry. Isoprenoid CKs were detected in all species, aromatic CKs were not detected in any of the samples. The CK profile of Chondracanthus teedei (Mert. ex Roth) Kütz. was distinct in comparison to other species with para-topolin derivatives detected in low concentrations. The main auxins present in all species were free indole-3-acetic acid and indole-3-acetamide. ABA was present in all species analyzed except for Hypnea nigrescens Grev. ex J. Agardh. No ABA conjugates were detected in any species. These results confirm that plant hormones were common constituents in red seaweeds, with this being the first report of the occurrence of ABA in Rhodophyta.
