a Agarose gel electrophoretic patterns of supercoiled pBR322 plasmid DNA converted into the open circular by AAPH in the presence or absence of samples (10 μM). b The effects of samples on supercoiled pBR322 plasmid DNAconverted into the open circular by AAPH in the presence or absence of samples(10 μM). Lane 1: control (native pBR322 DNA, without AAPH); Lane 2: AAPH; Lane 3: AAPH + isoeugenol; Lane 4: AAPH + shikonin; Lane 5: AAPH + baicalein; Lane 6: AAPH + rosmarinic acid; Lane 7: AAPH + dihydromyricetin. The density of the supercoiled DNA form was quantified by Quantity One (Bio-Rad). Data are the average of three determinations; C open circular, S supercoil, AAPH 2,2′-azobis(2-methylpropionamidine)dihydrochloride
