Tetuin is the name originally allocated to a chemical constituent of the seeds of Oroxylum indicum, the Indian trumpetflower, known as टेटु tetu in Marathi. The original authors identified this chemical as the 6-O-glucoside of baicalein, a flavone, a type of flavonoid. Their identification was probably incorrect, as subsequent authors were able to demonstrate that baicalein 6-O-glucoside has different properties to the original tetuin from O. indicum seeds, and were unable to find baicalein glycosides in the seeds. Nevertheless, modern authors have used the name tetuin as a trivial name for baicalein 6-O-glucoside.
