摘要
介绍了银杏叶中烷基酚化合物的分离过程 ,并鉴定出烷基酚化合物单体 3类 6种 ,其中银杏酸类化合物 2种 ,白果酚类化合物 3种 ,白果二酚类化合物 1种。这些化合物经UV、IR、MS、1HNMR、13CNMR等波谱鉴定为 :3 (8 十五碳烯基 )苯酚 ;3 [4(Z) ,7(Z) 十七碳二烯基 ]苯酚 ;3 (10 十七碳烯基 )苯酚 ;6 (8 十五碳烯基 )水杨酸 ;6 (10 十七碳烯基 )水杨酸 ;5 (8 十五碳烯基 )间苯二酚。
A method for the extraction and isolation of alkylphenols in Ginkgo biloba leaves was introduced.Through silica gel column separation,TLC and HPLC preparations,six monomers were acquired.By UV,IR,MS, 1 H NMR and 13 C NMR,the structures of these compounds were determined,and were confirmed by comparison with literature.The structures of these compounds were identifited as:3 (8 pentadecenyl)phenol,3 \[4( Z ),7( Z ) heptadecadienyl\]phenol,3 (10 heptadecenyl)phenol,6 (8 pentadecenyl)salicylic acid,6 (10 heptadecenyl)salicylic acid and 5 (8 pentadecenyl)resorcinol.The position of the double bonds in compound 3 [4( Z ),7( Z ) heptadecadienyl]phenol was determined from the GC MS spectrum of its oxide and methylated products.
