Abstract:

目的:研究藏产鳞腺杜鹃地上部分的化学成分。方法:利用多种色谱方法对其成分进行分离纯化,通过理化性质及NMR、MS波谱数据解析鉴定化合物的结构。结果:从中分离得到18个化合物,分别鉴定为:何帕醇-B(1),羽扇豆醇(2),熊果酸(3),扁蓄苷(4),槲皮素(5),杨梅素(6),金丝桃苷(7),杨梅素-3'-O-β-D-吡喃木糖苷(8),(+)-花旗松素-3-O-α-L-吡喃阿拉伯糖苷(9),(+)-花旗松素-3-O-β-D-吡喃葡萄糖苷(10),lyoniside(11),confluentin(12),2-(4-hydroxyphenyl)-ethyltriacontanoate(13),2,6-二甲氧基-4-羟基苯酚-1-O-β-D-吡喃葡萄糖苷(14),(-)-2-羟基-5-(2-羟乙基)苯-O-β-D-吡喃葡萄糖苷(15),(-)-isolariciresinol(16),isofraxoside(17),2,4,6-trihydroxacetophenone-3,5-di-C-β-D-glucoside(18)。结论:化合物1,13-18为首次从杜鹃花属植物中分离得到,其余化合物均为首次从该种植物中分离得到。
