Abstract
An HPLC method is described for the analytical separation of two novel diketopiperazine isomers isolated from a fungal culture, Tolypocladiu m sp. (SCF-0729). Separation was achieved on a highperformance polyvin yl alcohol silica gel column with a 1-chlorobutane: methanol gradient system. Selectivity, retention and resolution obtained with this suppo rt were all highly reproducible. Direct scale up of analytical methodo logy allowed for the preparative separation of this isomeric pair.
