Abstract

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 compoundwas established as 1,5-epoxy-3-hydroxy-1-(3,4-dihydroxy-5-methoxy-phenyl)-7-(3,4-dihydroxy-phenyl) heptane (1) on the basis of MS, 1D and 2D-NMR experiments.

摘要:通过活性跟踪,从生姜(Zingiber officinale Roscoe)中分离得到一个新的具抗氧化作用的二苯基环氧庚烷类成分,由其质谱、1D和2D-NMR等光谱数据,鉴定其结构为1,5-环氧-3-羟基-1-(3,4-二羟基-5-甲氧基苯基)-7-(3,4-二羟基苯基)庚烷 (1)。
