8-Hydroxygenistein
8-Hydroxygenistein (8-OHG) is an antioxidant that can effectively scavenge nitric oxide (NO) and superoxide anion (O₂⁻). 8-Hydroxygenistein belongs to ortho-dihydroxy isoflavones (ODI) and is abundantly present in dark soy sauce and light soy sauce. Its antioxidant activity is stronger than that of its parent compound genistein (HY-14596). The content of 8-Hydroxygenistein is positively correlated with the antioxidant capacity of soy sauce (r = 0.959), and it remains highly stable even after being heated in boiling water for 60 minutes. During the brewing and storage of soy sauce, 8-Hydroxygenistein effectively prevents oxidative damage, making it promising for use in food antioxidant research.

ROS/oxidative-stress fluorescent staining
ROS/oxidative-stress fluorescent staining uses cell-permeant fluorogenic probes that become fluorescent after oxidation inside cells or tissues; commonly used examples include DCFH-DA/DCFDA for broad cellular oxidant detection, DHE for superoxide-related signal detection, MitoSOX for mitochondrial superoxide-related signal detection, and CellROX probes for oxidative-stress-associated fluorescence readouts. The assay detects probe oxidation rather than a single ROS species unless the probe and analysis method have been chemically validated for that species. DCFH-DA enters cells, is deacetylated by intracellular esterases to DCFH, and produces fluorescent DCF after oxidation, so the readout is used as an operational measure of total cellular oxidative stress rather than a species-specific ROS measurement. DHE and MitoSOX can report superoxide-related oxidation, but red fluorescence alone can include non-specific ethidium-like oxidation products; HPLC or optimized spectral approaches are
