Kögl, Haagen Smit and Erxleben (1934) confirmed the finding of Salkowski and Salkowski in 1895 that urine contained B-indolyl acid, and found that this substance accounted for a portion of the activity of urine in promoting the growth of plants not accounted for by auxcntriolic acid and auxenolonic acid. Majima and Hoshino (1924) had already developed a method for the synthesis of B-indolyl-acetic acid so that it became evident to the authors that sufficient amounts of B-indolyl acetic could be made readily available for plant growth hormone studies.
