Use

Brefeldin A was isolated from Penicillium brefeldianum and recrystallised from aqueous MeOH/EtOAc or MeOH. Its solubility in H2O is 0.6mg/mL, 10mg/mL in MeOH and 24.9mg/mL in EtOH. The O-acetate recrystallises from Et2O/pentane and has m 130-131o, [] D +17o (c 0.95, MeOH). [Sigg Helv Chim Acta 47 1401 1964, UV and IR: H.rri et al.
