Objective To study the chemical constituents of the extraction of bamboo leaves of Phyllostachys nigra(Lodd.ex Lindl.) Munro var.henonis(Mitf.) Stepf.ex Rendle.Methods The compounds were isolated by chromatography on silica gel column,Sephadex LH-20,open ODS column and identified on the basis of physico-chemical constants and spectral analysis.Results Twelve compounds were isolated from EtOAc soluble fraction and n-BuOH soluble fraction of this plant and identified as β-sitosterol(1),tricin(2),daucosterol(3),butanedioic acid(4),5-methyluracil(5),tricin-7-O-β-D-glucopyranoside(6),vitexin(7),tricin-7-O-neohesperidoside(8),orientin(9),isoorientin(10),uracil(11),thymidine(12).Conclusions Compounds 4,5,6,8,11,12 are obtained from this genus for the first time.
