A New Antioxidant Cyclic Diarylheptanoid from the Rhizomes of Zingiber officinale

生姜中一新的抗氧化二苯基环氧庚烷成分(英文)

The bioassay was directed to the fractionation of the methanol extract of the rhizomes of Zingiber officinale Roscoe leading to the isolation of a new antioxidant cyclic diarylheptanoid. The structure of the new compound was established as 1, 5-epoxy-3-hydroxy-1-(3,4-dihydroxy-5-methoxy-phenyl)-7-(3,4-dihydroxyphenyl) heptane (1) on the basis of MS, 1D and 2D-NMR experiments.
