摘要
为了研究杜鹃兰Cremastra appendiculata干燥假鳞茎95%乙醇提取物的化学成分,采用多种色谱方法进行分离纯化,通过波谱数据及核对文献鉴定化合物结构。从其石油醚和乙酸乙酯萃取部位分离得到13个化合物,分别是4,4'-二甲氧基-9,9’10,10’-四氢-(1,1’-双菲)-2,2’,7,7'-四醇(1),4,4’,7,7’-四羟基.2,2'-二甲氧基.1,1’-双菲(2),3,5-二羟基-2,4-二甲氧基菲(3),大黄素甲醚(4),大黄酚(5),大黄素(6),芫花素(7),槲皮素(8),槲皮素3'-O-β-D-吡喃葡萄糖苷(9),3-甲氧基-4-羟基苯乙醇(10),丁香酸(II),香草醛(12),对羟基苯甲醛(13)。化合物1~3,5~12为首次从该属植物中分离得到。
Compounds were isolated through various chromatographic techniques and their structures were identified by spec- troscopic data analysis and comparison with those reported in the literatures. Thirteen compounds were obtained from the petroleum ether and ethyl acetate extracts. Their structures were identified as 4,4'-dimethoxy-9,9', 10,10'-tetrahydro- ( 1,1'-biphenanthrene ) -2, 2', 7,7 '-tetrol ( 1 ), 4,4', 7,7'-tetrahydroxy -2,2 '-dimethoxy- 1,1 '-biphenanthrene ( 2 ), 3, 5 -dihydroxy-2, 4 -dimethoxyphenanthrene (3), physcion (4), chrysophanol (5), emodin (6), genkwanin (7), quereetin (8), quercetin 3'-O-β-O-glucopyranoside (9), 3-methoxy-4-hydroxy phenylethanol (10) , syringic acid ( 11 ), vani]lin ( 12), and p-hydroxybenzaldehyde ( 13 ) , respectively. Com- pounds 1-3 and 5-12 are reported from this genus for the first time.
