Antioxidant effects of compounds 1, 2, 3, 5, 6, and 7 from PHT on Cu²⁺-mediated apoB-100 fragmentation. a The fragmentation of apoB-100 through analysis via SDS-PAGE. Five µM of each sample was run on an SDS-PAGE and BHT (2 µM) was used as a positive control. b Intensities of the apoB-100 bands are indicated as mean optical densities (absorbance units/mm²) ± SD values of three independent experiments. ^#p < 0.01 vs. native LDL; *p < 0.05, **p < 0.01 vs. ox-LDL using the Student’s t-test
