title: A new bisxanthone from Hypericum japonicum.
abstract: A new bisxanthone, named jacarelhyperols D (1), was isolated from the whole plant of Hypericum japonicum. Its chemical structure was elucidated as 6-[1',5',6'-trihydroxy-2''-(alpha-hydroxy-alpha-methyl)ethyl-3'',4''-dihydrofuran (2'',3'',3',4') xanthone-3''-oxyl]-1,3,5-trihydroxy-xanthone on the basis of spectroscopic analysis.
