  1. Structural modification improved catechin antioxidant and lipid-solubility traits
    DFT computational study reveals how structural modifications of catechins enhance antioxidant activity and lipid solubility simultaneously, overcoming traditional polarity-bioavailability.
  2. Gallic acid ester activity changed with chain length and hydroxyl groups
    Systematic evaluation of 14 gallic acid ester derivatives reveals inverse relationship between alkyl chain length and antioxidant activity, while hydroxyl substitution maintains efficacy.
