On biotransformation of bisphenol A by cultured suspension cells of Eucalyptus perriniana, three new biotransformation products, 2,2-bis(4-β-d-glucopyranosyloxyphenyl)propane, 2-(4-β-d-glucopyranosyloxy-3-hydroxyphenyl)-2-(4-β-d-glucopyranosyloxyphen yl)propane and 2-(4-β-d-glucopyranosyloxy-3-hydroxyphenyl)-2-(3-β-d-glucopyranosyloxy-4-h ydroxyphenyl)propane were isolated after three days incubation. Cultured suspension cells of E. perriniana are capable of regioselective hydroxylation and glycosylation of bisphenol A.
