Three new phenolic glycosides named eriosemasides A-C, one novel (named eriosematin F) and four known phenolic constituents were isolated from the n- BuOH-soluble fraction of the roots of Eriosema tuberosum. Their structures were established by spectroscopic analyses and chemical methods. All the phenolic compounds were fungitoxic except the phenolic glycosides.
