Antioxidant Effects of Some Ginger Constituents 总被引:26,自引:0,他引:26
The nonvolatile fraction of the dichloromethane extract of ginger rhizomes exhibited a strong antioxidative activity using linoleic acid as the substrate in ethanol-phosphate buffer solution. The fraction was purified by chromatographic techniques to provide five gingerol related compounds and eight diarylheptanoids. Among them, 12 compounds exhibited higher activity than α-tocopherol. The activity was probably dependent upon side chain structures and substitution patterns on the benzene ring. 相似文献
