Antioxidant Phenylpropanoid Glycosides from Buddleja Davidii
As a part of our ongoing search for antioxidative constituents from the genus Buddleja, we investigated the antioxidative activities of the solvent-partitioned fractions from the EtOH extract of the whole plant of Buddleja davidii. The n-BuOH-soluble fraction of the plant showed stronger antioxidative activity than that of the other fractions 7.39±0.04 μg/mL, IC50 in hydroxyl radical inhibitory activity test) which prompted us to carryout phytochemical studies on this plant.
The compounds 1–10 could lead to compounds for the treatment of oxidative stress-related human diseases. However, a further in vivo study would help in exploring the pharmacological properties of these compounds.
