Abstract
FOR marinobufagin, first isolated by Abel and Maeht1 from Bufo marinus and afterwards by Deulofeu and Mendive2 from B. paracnemis, Slotta and Neisser3 suggested the formula C27H38O6, at variance with C24H32O5 accepted by Jensen in many of his papers. They supposed that mar inobuf agin could contain one propionyl group.
