摘要
运用色谱分离材料和手段,结合现代波谱分析技术,从乌头属植物玉龙乌头中首次分离鉴定了12个非生物碱成分:4-hydroxy-4-(5-(hydroxymethyl)furan-2-yl)butan-2-one(1),(E)-4-[5-(hydroxymethyl)furan-2-yl]but-3-en-2-one(2),5-羟甲基糠醛(3),E-3-carboxy-2-petene-dioate 5-methyl ester(4),Z-3-carboxy-2-petenedioate 5-methyl ester(5),对羟基反式肉桂酸(6),对羟基顺式肉桂酸(7),藜芦酸甲酯(8),环氧松柏醇(9),酪醇(10),连翘脂素(11)和β-sitosteryl-3-O-β-D-glucopyranoside-2'-O-palmitate(12).其中化合物1是一个新天然产物,其数据经2D NMR进行了归属并首次报道.
By variety of chromatographies over various materials, twelve non-alkaloid compounds,including 4-hydroxy-4- ( 5- (hydroxymethyl) furan-2-yl) butan-2-one ( 1 ), (E) -4- [ 5- (hydroxymethyl) furan- 2-yl ] but-3-en-2-one (2) , 5-hydroxymethyl furfural ( 3 ), (E) -3-carboxy-2-petene-dioate 5 -methyl ester ( 4 ), (Z) -3-carboxy-2-petenedioate 5-methyl ester ( 5 ), (E) -p-hydroxycinnamic acid ( 6 ), (Z) -p-hydroxycin- namic acid ( 7), methyl veratrate ( 8 ), epoxyconiferyl alcohol ( 9 ) ,p-tyrosol ( 10 ), phillygenin ( 11 ) and fl- sitosteryl-3-O-β-D-glucopyranoside-2'-O-palmitate (12),were isolated from the roots of Aconitum stapfianum for the first time.Their structures were elucidated on the basis of spectroscopic methods.Compound 1 is a new natural product, and its full NMR spectral assignments were accomplished by 2D NMR for the first time.
