Compounds that bring about growth in soybean callus were extracted from yeast and malt extracts. In the former most of the activity is due to a compound that co‐chromatographed with zeatinriboside. This substance is also present in malt extract and coconut milk, together with a component which has the same elution volume as zeatin. Partition chromatography on Sephadex LH‐20 revealed the presence of an extremely active unidentified substance in both malt extract and coconut milk. Indications are that this compound is not diphenylurea.
