title: Bisxanthones from Hypericum japonicum: inhibitors of PAF-induced hypotension.
abstract: The CHCl3-soluble part (HJ) of the MeOH extract from Hypericum japonicum afforded new bisxanthones, jacarelhyperols A (1) and B (2). The structures were elucidated by spectral methods. These compounds and HJ showed significant inhibitory effects against PAF-induced hypotension by an in vivo evaluation method, which can reveal the pharmacological action of the test material.
