目的研究宽苞水柏枝Myricaria bracteata的化学成分。方法应用多种色谱技术进行分离纯化,根据化合物的理化性质和波谱数据鉴定化合物的结构。结果从宽苞水柏枝嫩枝95%乙醇提取物的醋酸乙酯萃取部位和大孔树脂30%乙醇洗脱部分中分离得到14个化合物,分别鉴定为丁香脂素(1)、(-)-南烛木脂酚(2)、(-)-异落叶松脂素(3)、Ν-反式阿魏酰基酪胺(4)、Ν-反式阿魏酰基-3-甲氧基酪胺(5)、Ν-反式阿魏酰基-2′-甲氧基酪胺(6)、山柰酚-3-O-β-D-吡喃葡萄糖醛酸-6″-甲酯(7)、槲皮素-3-O-β-D-吡喃葡萄糖醛酸-6″-甲酯(8)、槲皮苷(9)、鼠李柠檬素(10)、没食子酸(11)、没食子酸甲酯(12)、E-咖啡酸(13)、E-阿魏酸(14)。结论化合物1~6、14为首次从该属植物中分离得到,化合物7、8、12、13为首次从该植物中分离得到。
Aim To study the chemical constituents of Myricaria bracteata Methods A variety of chromatographic techniques were used for the isolation and purification. The structures of the compounds were identified based on the physicochemical properties and spectral data of the compounds. Results Fourteen compounds were isolated from the ethyl acetate extract of 95% ethanol extract of broadleaf Shuppok branch and 30% ethanol of macroporous resin. The compounds were identified as melatonin (1), - (-) - Lactoneol (3), N-trans Feruloyl tyramine (4), N-trans Feruloyl-3-methoxy tyramine (5), N-trans-feruloyl-2’-methoxytyrosamine (6), and kaempferol-3-O-β-D-glucopyranosidic acid- , Quercetin-3-O-β-D-glucopyranosoleate-6 "-methyl ester (8), quercitrin (9), murin LIC (10), gallic acid (11) Methyl acid ester (12), E-caffeic acid (13), E-ferulic acid (14). Conclusion Compounds 1-6, 14 were isolated from this genus for the first time. Compounds 7, 8, 12 and 13 were isolated from this plant for the first time.
