摘 要:目的对地黄叶的化学成分进行分离与结构鉴定。方法采用DiaionHP-20,ToyopeaAHW-40,SephadexLH-20,MCIGelCHP-20,硅胶等多种柱色谱技术进行分离纯化,并根据化合物的波谱数据和理化性质进行结构鉴定。结果从地黄叶的50%含水丙酮组织破碎提取物中分离并鉴定了27个化合物的结构,分别为对羟基苯甲酸(1),龙胆酸(2),6,7-二羟基香豆素(3),对羟基苯乙醇(4),3,4-二羟基苯乙醇(5),原儿茶酸(6),1,2,4-苯三酚(7),香叶木素(8),木樨草素-7—O-β-D-葡萄糖醛酸苷(9),芹菜素(10),2β,3β,19a-三羟基齐墩果-12-烯-13,28-二羧酸(11),2a,3β-二羟基齐墩果-12-烯-28-酸(12),glutinolicacid(13),β-hydroxyacteoside(14),松果菊苷(15),焦地黄苯乙醇苷B,(16),毛蕊花糖苷(17),异毛蕊花糖苷(18),筋骨草醇(19),梓醇(20),8-表番木鳖酸(21),木樨草素(22),齐墩果酸(23),熊果酸(24),齐墩果酮酸(25),β-谷甾醇(26),胡萝卜苷(27)。结论化合物1~14,23~25为首次从该植物中分离得到。OBJECTIVE To study the chemical constituents in the leaves of Rehmannia glutinosa Libosch. METHODS The compounds were isolated and purified by Diaion HP-20, Toyopearl HW-40, Sephadex LH-20, MCI Gel CHP-20, and silica gel column chromatography, and the structures were elucidated on the basis of spectral data and physiochemical properties. RE- SULTS Twenty-seven compounds were obtained from the 50% acetone extract, and their structures were identified as p- hydroxybenzoic acid ( 1 ) , gentisic acid ( 2 ) , 6,7-dihydroxycoumarin ( 3 ) , p-hydroxyphenylethyl alcohol (4) , 3,4-dihydroxyphe- nylethyl alcohol ( 5 ) , protocatechuic acid ( 6 ) , 1,2,4-trihydroxybenzene ( 7 ) , diosmetin ( 8 ) , luteolin-7-O-β-D-glucuronide ( 9 ) , apigenin ( 10 ) , 2/3, 3,8, 19a-trihydroxyolean-12-ene-13,28-dioic acid ( 11 ) , 2a, 3,8-dihydroxyolean-12-ene-28-oic acid (12) , glutinolic acid ( 13 ) , /3-hydroxyacteoside ( 14 ) , echinacoside ( 15 ) , jionoside B1 ( 16 ) , acteoside ( 17 ) , isoacteoside ( 18 ) , ajugol ( 19 ) , catalpol ( 20 ) , 8-epiloganic acid ( 21 ) , luteolin ( 22 ) , oleanolic acid ( 23 ) , ursolic acid ( 24 ) , oleanonic acid(25) , β-sitosterol(26) and daucosterol(27). CONCLUSION Compounds 1 -14 and 23 -25 are isolated from this plant for the first time.
