摘要
目的:研究铁皮石斛的化学成分。方法:利用硅胶、凝胶柱色谱及制备高效液相色谱等方法进行分离,根据波谱数据和理化性质鉴定其结构。结果:从铁皮石斛中分离得到了20个化合物,分别鉴定为3,4′-二羟基-5-甲氧基联苄(1),二氢白藜芦醇(2),dendromoniliside E(3),denbinobin(4),2,4,7-三羟基-9,10-二氢菲(5),钩状石斛素(6),(-)-loliolide(7),腺苷(8),尿苷(9),鸟苷(10),蔗糖(11),5-羟甲基糠醛(12),反式阿魏酸二十八烷基酯(13),对羟基反式肉桂酸三十烷基酯(14),对羟基顺式肉桂酸三十烷基酯(15),胡萝卜苷(16),β-谷甾醇(17),十六烷酸(18),三十一烷醇(19)及十七烷酸(20)。结论:化合物1~20均为首次在铁皮石斛中分离得到。
The column chromatography on silica gel,sephadex LH-20 preparative HPLC were used to separate and purify the compounds from the stems of Dendrobium candidum.Twenty compounds were isolated and identified as 3,4′-dihydroxy-5-methoxybibenzyl(1),dihydroresveratrol(2),dendromoniliside E(3),denbinobin(4),2,4,7-trihydroxy-9,10-dihydrophenanthrene(5),aduncin(6),(-)-loliolide(7),adenosine(8),uridine(9),guanosine(10),sucrose(11),5-hydroxymethyl-furaldehyde(12),n-octacostyl ferulate(13),defuscin(14),n-triacontyl cis-p-coumarate(15),daucosterol(16),β-sitosterol(17),hexadecanoic acid(18),hentriacontane(19),and heptadecanoic acid(20).Their structures were elucidated on the basis of spectroscopic data and physicochemical properties.All of the compounds were isolated from this plant for the first time.
