  Dihydropyranocoumarins from roots of Peucedanum japonicum

  摘要：

  Two new angular-type dihydropyranocoumarins, peujaponisin and (-)-visnadin, were isolated from the roots of Pencedanum japonicum and the structures determined as 3'(S)-senecioyloxy-4'(S)-isovaleryloxy-3',4'-dihydroseselin and 3'(S)-2-methylbutyryloxy-4'(S)-acetoxy-3',4'-dihydroseselin, respectively, by spectroscopic analysis and chemical reactions.
