Abstract:
AIM: To evaluate the antioxidant properties in vitro of Longxuejie Capsule (Sanguis draconis) (LC). METHODS: The antioxidant activities of Longxuejie Capsules were investigated by employing several external assay systems, including 1,1-diphenyl-2-picrylhydrazyl (DPPH?)/peroxide anion/hydroxyl radical-scavenging, reducing power assay system, peroxidation of polyunsaturated fatty acid from yolk lipoprotein induced by Fe~ 2+ method, and ?-carotene/linoleic acid assay system. RESULTS: The LC showed scavenging activity against free radicals, such as DPPH?, peroxide anion and hydroxyl radicals. LC also exhibited effective reducing power and powerful inhibitory effects on peroxidation of polyunsaturated fatty acid from yolk lipoprotein induced by Fe~ 2+ . Furthermore, LC showed markedly inhibitory effect on ?-carotene/linoleic acid assay system. CONCLUSION: Longxuejie Capsule has obvious antioxidant activities in vitro
