Tetuin is the name originally allocated to a chemical constituent of the seeds of Oroxylum indicum, the Indian trumpetflower,^[1] 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,^[2] and were unable to find baicalein glycosides in the seeds.^[3] Nevertheless, modern authors have used the name tetuin as a trivial name for baicalein 6-O-glucoside.^[4]
