Based on DPPH radical scavenging activity and lipid peroxidation inhibitory activity, the MeOH extracts of 139 crude drugs were screened in order to search for antioxidants. Among tested samples, the extracts from the seed of Nelumbo nucifera, the fruit of Terminalia chebula var. gangetia, the root of Salvia miltiorhiza, the fruit of Ziziphus jujuba var. innermis, the root bark of Paeonia moutan, the fruit of Rubus coreanus, the fruit of Zanthoxylum schinifolium, the lignum of Caesalpinia sappan, the leaf of Pinus densiflora, the rhizome of Alpinia officinarum, the fruit of Syzygium aromaticum, the ramulus and uncus of Uncaria rhynchophylla, the root bark of Lycium chinense, and the fruit of Alpinia katsumadai showed a relatively strong antioxidative activity. Furthermore, the BuOH fraction from the extract of N. nucifera showed a potent activity in each assay. The isolation of bioactive compounds has been carried out and will be reported in the next paper.
