To investigate the chemical constituents from the shoot of Phyllostachys edulis.Normal-phase, reversed-phase silica gel, Sephadex LH-20 porous polymer gel column and HPLC chromatography were used for isolation. Spectroscopic methods (13C-NMR, 1H-NMR, DEPT and EI-MS) were used for identification.Eleven compounds were isolated and elucidated, which were skimmin(I), liquiritienin(II),1-(4-hydroxy-3-methoxyphenyl)-1-propanone(III), syringicaldehyde(IV), vanillin(V), isoliquiritigenin(VI), 4-hydroxybenzoic acid(VII), methyl p-hydroxy benzeneacetate (VIII), 5,7-dihydroxy-8-methoxyflavone (IX), daucosterol(X) and β-sitosterol(X).All the compounds are obtained from this plant for the first time, and compounds VI, VIII and IX are firstly isolated from the plants of this genus.
