Abstract: A new flavonoloside which was isolated from Magnolia biondii Pamp,collected in Henan Provinee was found for the first time. Its chemical component was determined to be 4',5,7-trihydroxy-flavonol-β-7-O-(6"-P-coumoroyl)-D-Glucosyloside by using various NMR spectra(including PBB,APT,NOEDS,COSY,HETCOR,HMQC and HMBC etc.) and is named Biondnod A.

Key words: Magnolia biondii Pamp., Biondnoid A, NMR
