title: Scavenging effects of phenylpropanoid glycosides on superoxide and its antioxidation effect.
abstract: The antioxidative activities of six phenylpropaniod glycosides (PPG) extracted from Pedicularis striata and Pedicularis lasiophrys for inhibiting the lipid peroxidation induced by Fe2+/ascorbic acid in mouse liver microsome may be related to the number and steric position of phenolic hydroxyl groups (PHG) they possess (32.5 mumol.L-1 to 65.0 mumol.L-1). The scavenging effects of PPG for superoxide produced by NBT/PMS/NADH system may be related to both the number of PHG and their conjugated system (16.0 mumol.L-1 to 65.0 mumol.L-1).
