Abstract
Agroclavine was converted to setoclavine and isosetoclavine in crude extracts from Claviceps sp. SD 58. The ratio of setoclavine to isosetoclavine was 0.95. The conversion with boiled crude extract was 68% of the conversion with unboiled extract. In a thioglycolate-iron (II) system at 40 degrees for 5 hr, 45.5% of agroclavine was converted to setoclavine and isosetoclavine. At 70 degrees for 4 hr in the thioglycolate-iron (II) system, 4% of 4-dimethylallyltryptophan was converted to clavicipitic acid.
