    Three compounds, vanillic acid, p-hydroxylcinnamic acid, p-hydroxybenzaldehyde have been isolated from the ethylacetate extract of Sparganium stoloniferum Buch.-Ham roots using silica gel open column chromatography, preparative thin-layer chromatography (pTLC) and reverse phase high performance liquid chromatography. The structures of the compounds were established on the basis of IR, extensive 1D NMR, and MS analyses. The ethylacetate (EtOAc) extract, vanillic acid, and p-hydroxybenzaldehyde showed α-glucosidase inhibition activity of 72.71%, 20.13%, and 30.42%, at the concentration of 10 ㎍/mL, respectively. The EtOAc extract exhibited strong antioxidant activity with an IC<SUB>50</SUB> value of 24.37 ㎍/mL against DPPH radical scavenging activity, the vanillic acid, p-hydroxylcinnamic acid, and p-hydroxybenzaldehyde with an IC<SUB>50</SUB> value of 2.10 μM, 1.59 μM, and 2.72 μM against DPPH, respectively.
