摘要 Aim To study the chemical constituents from the stems of Xylosma controversum Clos. Methods The constituents were isolated by solvent extraction, repeated chromatography with silica gel, Sephadex LH-20, and RP-18 columns. The structures were elucidated by spectral analysis. Results Thirteen compounds were isolated and their structures were identified as (-)-syringaresinol (1), syringaresinol-4-O-β-D-glucopyranoside (2), syringaresinol-4,4′-bis-O-β-D-glucopyranoside (3), (±)-catechin (4), catechin-3-O- β-D-glucopyranoside (5), catechin-5-O-β-D-glucopyranoside (6), 1,3-bis-(4-hydroxy-3,5-dimethoxyphenyl)-1,3-propanediol (7), (R)-(+)-chaulmoogric acid (8), friedelin (9), uracile (10), benzoic acid (11), vaniUic acid (12), and 4-hydroxybenzoic acid (13). Conclusion All the compounds described above were isolated from this genus for the first time. 目的对南岭柞木Xylosma controversum Clos茎的化学成分进行研究。方法应用各种色谱方法分离,应用波谱技术确定结构。结果分离鉴定了13个化合物,分别是:(-)-丁香树脂酚(1),丁香树脂酚-4-O-β-D-葡萄糖苷(2),丁香树脂酚-4,4'-O-β-D-双葡萄糖苷(3),(±)-儿茶素(4),儿茶素-3-O-β-D-葡萄糖苷(5),儿茶素-5-O-β-D-葡萄糖苷(6),1,3-bis(4-hydroxy-3,5-dimethoxyphenyl)-1,3-propanediol(7),(R)-(+)-大风子油酸(8),木栓酮(9),尿嘧啶(10),苯甲酸(11)香草酸(12),对羟基苯甲酸(13)。结论以上化合物均为首次从柞木属植物中分离得到。
