Diosmetin powder is a flavonoid compound commonly found in the peel and pulp of citrus fruits, including oranges, lemons, limes, and grapefruits. Besides citrus fruits, it is also found in plants such as persimmons, oregano, chamomile, and saffron. As a natural flavonoid, it possesses strong antioxidant activity and exhibits specific scavenging effects on DPPH and O2. The scavenging rate increases with concentration, demonstrating a dose-response relationship. After mixing with 1,1-diphenyl-2-trinitrophenylphthalic acid free radicals, the absorbance of Diosmetin at 517 nm was compared with and without the additive. The absorbance decreased, indicating a single electron pairing phenomenon with DPPH and a reduction in the DPPH state of the element. This change demonstrates its ability to scavenge DPPH free radicals, exhibiting strong antioxidant activity, and being more active than VTC.
