摘要
通过系统的植物化学分离分析方法,研究骆驼蹄瓣中的萜类化学成分。运用硅胶柱色谱、凝胶柱色谱(Sephadex LH-20)对乙酸乙酯部位进行分离纯化,然后通过现代波谱学鉴定方法(1H-NMR,13C-NMR,MS)和结合文献数据分析确定化合物的结构。从乙酸乙酯部位分离并鉴定13个化合物,结构分别为1-羟基茅苍术醇(1),茅苍术醇(2),白术内酰胺(3),β-桉叶醇(4),5α-氢过氧基-β-桉叶醇(5),12-羟基-2-酮基-1-瓦伦烯(6),毛脉五味子醇A(7),(6S,7E)-6-羟基-4,7-大柱烯-3,9-二酮(8),3-羟基-5α,6α-环氧-β-紫罗兰酮(9),(3S,5R,6S,7E)-3,5,6-三羟基-7-大柱烯-9-酮(10),(6R,7E,9R)-9-羟基-4,7-大柱烯-3-酮(11),(S)-3-羟基-β-紫罗兰酮(12),布卢门醇A(13)。其中化合物1~7为倍半萜,8~13为大柱烷类降倍半萜,以上化合物均为首次从骆驼蹄瓣中分离得到,化合物1为新的天然产物。
This study was to investigate the chemical constituents of the aerial part of Zygophyllum fabago,by phytochemical methods. The compounds were isolated by silica gel and Sephadex LH-20 column chromatographies from the Et OAc extract. Their structures were characterized by various spectroscopic data(1H-NMR,13C-NMR,MS) and comparison with the literature. As a result,thirteen compounds were isolated and their structures were identified as 1-hydroxyhinesol( 1),hinesol( 2),atractylenolactam( 3),β-eudesmol( 4),5α-hydroperoxy-β-eudesmol( 5),12-hydroxy-valenc-1( 10)-en-2-one( 6),pubinernoid A( 7),( 6S,7E)-6-hydroxy-4,7-megastigmadien-3,9-dione( 8),3-hydroxy-5α,6α-epoxy-β-ionone( 9),( 3S,5R,6S,7E)-3,5,6-trihydroxy-7-megastigmen-9-one( 10),( 6R,7E,9R)-9-hydroxy-4,7-megastigmadien-3-one( 11),( S)-3-hydroxy-β-ionone( 12),and blumenol A( 13). Compounds 1-7 were sesquiterpenoids and 8-13 were megastigmane type norsesquiterpenoids. All the compounds were obtained from Z. fabago for the first time,and compound 1 was a new natural product.
