From the plants of the antidrug medication Heantos 4, 10 phthalide derivatives, 5 carbohydrate derivatives, 6 fatty acids, 2 acetylenic compounds, 9 oligosaccharide esters as well as 10 other structures have been isolated. Their structures have been elucidated by the mass, NMR spectroscopy and comparison with published data. A survey on biological activities of isolated compounds showed a good agreement between their activities and the affectivities of Heantos 4, such as tonic, tranquilizing, antidepressing and neuro-protecting effects.
