title: Radical scavengers from the entomogenous deuteromycete Beauveria amorpha.
abstract: The culture medium of Beauveria amorpha Hohn. exhibited strong radical scavenging properties. Activity-directed fractionation assisted by a radical scavenging assay on TLC afforded two active compounds which were identified as 6-methyl-2,4-dihydroxyphenyl 4-O-methyl-beta-D-glucopyranoside (1) and (-)-terredionol (2). Compound 1 displays radical scavenging and lipid peroxidation inhibitory activity comparable to those of TroloxC, ascorbic acid or quercetin.
