Taxoquinone is an antioxidant derived from Metasequoia glyptostroboides and belongs to the diterpenoid class of compounds. At a concentration of 150 μg/mL, Taxoquinone exhibits a maximum inhibition of DPPH radicals of 81.29%, demonstrating superior antioxidant activity compared to Ascorbic acid and α-tocopherol at the same concentration[1].
