通过硅胶,Sephadex LH-20葡聚糖凝胶,ODS反相柱色谱等分离技术对鸢尾科Iridaceae植物德国鸢尾Iris germanica根茎的化学成分进行分离纯化,采用理化性质及波谱分析方法对分离得到的化合物进行结构鉴定。从该植物根茎中分离得到21个化合物,分别鉴定为商陆素(1),5,3,3’-三羟基-7,4’-二甲氧基黄烷酮(2),5,7,4’-三羟基双氢黄酮(3),cirsiliol-4’-glucoside(4),3β,4’-dihydroxy-7,3’-dimethoxy flavornone-5-O-β-D-glucopyranoside(5),染料木素(6),irilin D(7),muningin(8),5,7,4’-三羟基-6,3’,5’-三甲氧基异黄酮(9),鸢尾苷元(10),野鸢尾苷元(11),鸢尾苷(12),野鸢尾苷(13),芒果苷(14),irisxanthone(15),焦谷氨酸(16),2,4’,6-trihydroxy-4-methoxybenzophenone-2-O-β-D-glucoside(17),茶叶花宁(18),草夹竹桃苷(19),β-谷甾醇(20),胡萝卜苷(21)。其中化合物1~9,16,17为首次从德国鸢尾中分离得到,化合物8,9为首次从鸢尾属植物中分离得到,化合物1,4,17为首次从鸢尾科植物中获得。
The chemical constituents from Iris germanica Iris germanica rhizome were isolated and purified by silica gel, Sephadex LH-20 Sephadex LH-20 Sephadex LH-20 column and ODS reverse phase column chromatography. The physicochemical properties and spectral analysis of isolated compounds Structural identification. Twenty-one compounds were isolated from the rhizomes of this plant and identified as melatonin (1), 5,3,3’-trihydroxy-7,4’-dimethoxyflavanone (2), 5,7 (3), cirsiliol-4’-glucoside (4), 3β, 4’-dihydroxy-7,3’-dimethoxy- flavornone-5-O- β-D-glucopyranoside (5) , Genistein (6), irilin D (7), muningin (8), 5,7,4’-trihydroxy-6,3 ’, 5’-trimethoxyisoflavone (9) 10), tectorigenin (11), tectorigen (12), wild tectorigen (13), mangiferin (14), irisxanthone (15), pyroglutamic acid (16), 2,4 ’, 6- trihydroxy-4-methoxybenzophenone-2-O-β-D-glucoside (17), tea Hua Ning (18), oleander glycosides (19), β-sitosterol (20), daucosterol (21). Compounds 1 to 9, 16 and 17 were isolated from Iris germanica for the first time. Compounds 8 and 9 were isolated from Iris for the first time. Compounds 1, 4 and 17 were isolated from Iris for the first time.
