摘  要:研究臭椿Ailanthus altissima皮的化学成分。采用硅胶,Sephadex LH-20,ODS,HPLC等色谱方法,从臭椿干皮95%乙醇提取物中分离得到11个化合物,通过理化性质和波谱数据鉴定为木脂素类化合物,分别为(+)-新橄榄树脂素(1),prunustosanan AI(2),(7S,8R)-4,7,9,9'-四羟基-3,3'-二甲氧基-8-O-4'-新木脂素(3),(7R,8S)-4,7,9,9'-四羟基-3,3'-二甲氧基-8-O-4'-新木脂素(4),(7S,8R)-1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-hydroxypropyl)-2,6-dimethoxyphenoxy]-1,3-propanediol(5),pinnatifidanin B V(6),pinnatifidanin B VI(7),(7R,7'R,7″S,8S,8'S,8″S)-4',4″-dihydroxy-3,3',3″,5-tetramethoxy-7,9':7',9-diepoxy-4,8″-oxy-8,8'-sesquineolignin-7″,9″-diol(8),hedyotol D(9),5-(2-propenyl)-7-methoxy-2-(3,4-methylenediovxyphenyl)benzofuran(10),(7R,8S,7'E)-guaiacyl-glycerol-β-O-4'-sinapyl ether(11)。化合物均为首次从该植物中分离得到。Eleven lignans were isolated from the ethanol extract of the barks of Ailanthus altissima through various column chroma- tography methods including silica gel, Sephadex LH-20, ODS and HPLC. By physical, chemical and comprehensive spectroscopic methods, their structures were identified as ( + ) -neoolivil ( 1 ), prunustosanan AI ( 2 ), ( 7S, 8R) -guaiacyl-glycerol-β-O-4'-neolignan (3), (TR, 8S) -guaiacyl-glycerol-β-O-4'-neolignan ( 4), (7S, 8R) -1- (4-hydroxy-3-methoxyphenyl) -2- [ 4- (3-hydroxypropyl) -2,6-di- methoxyphenoxy 1-1,3-propanediol (5), pinnatifidanin B V ( 6 ), pinnatifidanin B VI ( 7 ), ( 7R, 7'R, 7"S, 8S, 8' S, 8"S ) -4', 4"-di- hydroxy-3,3', 3", 5-tetramethoxy-7,9' : 7', 9-diepoxy-4,8"-oxy-8,8 '-sesquineolignan-7", 9"-diol (8), hedyotol D (9), 5- (2-propenyl) - 7-methoxy-2- (3,4-methylenediovxyphenyl) benzofuran ( 10 ), and ( 7R, 8S, 7' E) -guaiacyl-glycerol-β-O-4'-sinapyl ether ( 11 ). All of these compounds were isolated from this plant for the first time.
