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