| Additional Infomation |
According to reports, turmeric contains octahydrocurcumin, and there is relevant data available.
1. Chemical background: - Octahydrocurcumin is a hydrogenated derivative of curcumin (the main active ingredient of curcumin); its structure differs from curcumin in that the conjugated double bond in the central heptadenone chain is completely saturated, thereby improving its chemical stability and water solubility[2][3] - It is the main in vivo metabolite of curcumin, formed by the reduction of curcumin double bonds by liver enzymes (such as aldehyde reductase)[2] 2. Mechanism of action: - Antioxidant mechanism: Octahydrocurcumin scavenge free radicals (DPPH, ABTS, superoxide anion) through its phenolic hydroxyl group (electron donor), and inhibit lipid peroxidation by chelating Fe²⁺ (a pro-oxidation metal ion)[3] - Anti-inflammatory mechanism: Octahydrocurcumin inhibits LPS-induced inflammation by inhibiting NF-κB activation - blocking the nuclear translocation of the p65 subunit, thereby reducing the inflammatory response. Transcription of pro-inflammatory cytokines (TNF-α, IL-6)[2] 3. Comparison of activities: - Antioxidant activity: octahydrocurcumin has weaker free radical scavenging activity than curcumin (e.g., DPPH IC₅₀ 8.5 μM vs. curcumin 2.8 μM), but stronger lipid peroxidation inhibitory activity (curcumin IC₅₀ 18.5 μM vs. octahydrocurcumin 12.3 μM)[3] - Anti-inflammatory activity: octahydrocurcumin has about 80% of the anti-inflammatory potency of curcumin (e.g., TNF-α IC₅₀ 15.2 μM vs. curcumin 12.8 μM), but better stability in biological systems[2] |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
