Antioxidative Constituents from Dendrobii Herba(Stems of Dendrobium spp.)[Reference: WebLink
METHODS AND RESULTS:
Ten phenolic compounds; gigantol, moscatilin, Tristin, crepidatin, 4-hydroxy-3,3',4',5-tetramethoxybibenzyl, 2,4,8-trimethoxyphenanthrene-3,7-diol, confusarin, moscatin, medioresinol and syringaresinol were isolated from Dendrobii Herba (stems of Dendrobium spp.), which is used as one of the important crude drugs for tonics, antipyretics and stomach agents, and their structures were elucidated on the basis of spectroscopic data.
All of these compounds showed stronger antioxidative activity than BHA by the ferric thiocyanate method.
