Abstract
Bioactivity-directed fractionation of the CH2Cl2/MeOH (2:1, v/v) extract of the roots of Petiveria alliacea, using mutant yeast strains of Saccharomyc es cerevisiae and fungi Cladosporium cladosporioides and C. sphaerospermum led to the isolation of dipropyl disulphide (1), dibenzyl sulphide (2), dib enzyl disulphide (3), dibenzyl trisulphide (4), dibenzyl tetrasulphide (5), benzylhydroxymethyl sulphide (6) and di(benzyltrithio) methane (7). Of the se, 5-7 are new compounds and this is the first report of the natural occur rence of 2 and 3. (C) 2001 Elsevier Science Ltd. All rights reserved.
