It was confirmed that korean scabby barley during the summer of 1963 was infected with Gibberella zeae. Feeding experiments showed that the diseased grain was toxic and induced emesis in pigs. The concentrated extracts which contained the emetic principle were prepared by refluxing the grain with methanol or water for 5 hours and then concentrating the filtrates and the washing in vacuum. Animal tests proved that methanol extraction for the emetic principle was more effective than extraction with water.
