Antihemorrhagic principles were isolated from Hypericum erectum THUNB. (Hypericaceae) by a combination of countercurrent distribution and Sephadex LH-20 column chromatography, and identified as wedelolactone [5', 5, 6-trihydroxy-7'-methoxycumarino-(3', 4' : 3, 2)-coumaronel (1, 8, 9-trihydroxy-3-methoxy-6-oxo-6H-[z] benzofuro [3, 2-c] [z] benzopyran) and desmethylwedelolactone [5', 7', 5, 6-tetrahydroxyl-cumarino-(3', 4' : 3, 2)-coumarone] (1, 3, 8, 9-tetrahydroxy-6-oxo-6H-[z]-benzofuro [3, 2-c] [z] benzopyran).
