Abstract The isolation of 7,4'-dihydroxy-8-methylflavan (1) from the dichloromethane extract of Pancratium littorale stem was guided by an assay for free radical scavenging activity towards the 2,2-diphenyl-1-picryI-hydrazyl radical (DPPH). The structure of 1 was established by spectrometric methods including UV, EI mass spectrometry, H-1 and C-13-NMR. The free radical scavenging properties of 1 were quantified in solution using spectrophotometry. (C) 2001 Elsevier Science B.V. All rights reserved.
