%X A new phloroglucinol diglycoside 1, together with eight known compounds, were isolated from Hypericum japonicum Thunb. The structure of the new compound 1 was determined by spectroscopic methods to be 4,6-dimethyl-5-O-[¦Á-L-rhamnopyranosyl-(1¡ú6)-¦Á-D-glucopyranosyl] multifidol. Different solvent extracts of Hypericum japonicum Thunb. were tested for in vivo antihypoxic activity using mice, with the EtOAc extract showing better activity.
