title: Isolation of virus-cell fusion inhibitory components from the stem bark of Styrax japonica S. et Z.
abstract: Five compounds, styraxjaponoside A (1), matairesinoside (2), egonol glucoside (3), dihydrodehydrodiconiferyl alcohol 9'-O-glucoside (4), and styraxjaponoside B (5) were isolated from the stem bark of Styrax japonica. Among them, compounds 1 and 5 showed significantly high virus-cell fusion inhibitory activity. In addition, compound 5 exhibited almost equivalent virus-cell fusion inhibitory activity to that of dextran sulfate, which is used as a positive control.
