Isolation of Gregatin A from Phialophora gregata by Preparative High-Pressure Liquid Chromatography.
A method was developed for the production and purification of gregatin A from Phialophora gregata NRRL 13198 cultured on rice at 20 degrees C for 28 days. Liquid extraction followed by high-pressure liquid chromatography afforded 247.0 mg of crystalline gregatin A per kg of rice.
