    AbstractThe antioxidant activities of each extract from two Juncaceae plants were determined by using DPPH free radical scavenging method. The experimental results indicated that EtOAc extract of Juncus effusus L. had the strongest antioxidation activiies. The antioxidant activities offour compounds isolated from this plant were tested. The results showed that thecompound 3 displayed modrate scavenging DPPH free radical activities compared with BHT.
