Vanillic acid 4-O-β-D-glucopyranoside	Structural Classification Simple Phenylpropanols Rubiaceae Phenylpropanoids Plants Gardenia jasminoides Ellis Source Classification	HIV Integrase
Vanillic acid 4-O-β-D-glucopyranoside is a vanillic acid glycoside with moderate antioxidant activity. Vanillic acid 4-O-β-D-glucopyranoside scavenges DPPH free radicals and superoxide anion radicals, and inhibits AAPH-induced lipid peroxidation in the linoleic acid system. The IC₅₀ value of Vanillic acid 4-O-β-D-glucopyranoside against HIV-1 integrase is >100 μg/mL, indicating that it is not an effective HIV-1 integrase inhibitor. Vanillic acid 4-O-β-D-glucopyranoside is isolable from the ethyl acetate extract of Gardeniae Fructus.
