摘要:
目的:分离鉴定竹叶兰干燥根茎中的化学成分.方法:乙醇提取,硅胶、Sephadex LH-20及ODS柱色谱分离,采用UV,NMR和MS等方法确定化合物的结构.结果:分得5个化合物,分别为7-羟基-2,4-二甲氧基-9,10-二氢菲(7-hydroxy-2,4-dimethoxy-9,10-dihydrophenanthreneⅠ), 4,7-二羟基-2-甲氧基-9,10-二氢菲(4,7-dihydroxy-2-methoxy-9,10-dihydrophenanthrene Ⅱ), 2,7-二羟基-4-甲氧基-9,10-二氢菲(2,7-dihydroxy-4-methoxy-9,10-dihydrophenanthrene Ⅲ), 7-羟基-2-甲氧基-菲-1,4-二酮(7-hydroxy-2-methoxy-phenanthrene-1,4-dione Ⅳ),和7-羟基-2-甲氧基-9,10-二氢菲-1,4二酮(7-hydroxy-2-methoxy-9,10-dihydrophenanthrene-1,4-dione Ⅴ).结论:5个菲类化合物均为首次从竹叶兰中分离得到.
