目的研究毛竹竹叶提取物中的化学成分。方法采用硅胶柱、Sephadex LH-20、开放式ODS柱色谱分离,根据理化常数和波谱分析对化合物进行鉴定。结果 从该植物的 EtOAc 可溶性部分和 n-BuOH 可溶性部分中分离得到 12 种化合物,鉴定为 β-谷甾醇(1)、三辛(2)、胡萝卜素(3)、丁二酸。 酸(4),5-甲基尿嘧啶(5),tricin-7-O-β-D-吡喃葡萄糖苷(6),牡荆素(7),tricin-7-O-新橙皮苷(8),荭草苷(9),异荭草苷(10),尿嘧啶(11),胸苷(12)。 结论 得到化合物4,5,6,8,11,12 首次从该属中分离出来。
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.
