摘要(Abstract):

降香为我国Ⅱ级珍稀濒危保护植物降香黄檀的心材,资源稀缺,价格昂贵。为寻找降香药材替代品,该课题组综合运用硅胶、Sephadex LH-20和半制备高效液相色谱等色谱技术方法,对其同属植物阔叶黄檀心材的70%乙醇提取物进行系统化学成分研究,结果从该植物中分离鉴定出新黄酮类成分16个,包括8个黄檀酚类(1~8)、3个黄檀醌类(9~11)、2个黄檀内酯类(12,13)、2个苯酰苯类(14,15)、1个其他类型新黄酮(16),其中化合物3,7,11为首次从黄檀属植物中分离得到,化合物2,4,5,6,8,14,15为首次从阔叶黄檀中分离得到,且16个新黄酮类成分中有10个与文献报道的降香药材中新黄酮类成分相同。
Dalbergiae Odoriferae Lignum is derived from heartwood of Dalbergia odorifera,which is national Ⅱ level of rare and endangered protective plants in China. Its resources are scarce and its price is high. In order to find substitutes of D. odorifera,the chemical constituents of 70% ethanol extract of heartwood of D. catifolia were systematically studied by using silica gel,Sephadex LH-20 column chromatography,and semi-preparative HPLC. Sixteen neoflavanoids were isolated and identified as eight dalbergiphenols( 1-8),three dalbergiones( 9-11),two dalbergins( 12,13),two benzophenones( 14,15) and one other type neoflavanoids( 16) based on spectroscopic data analyses and/or comparing the spectroscopic data with those in literature. Among them,compounds 3,7 and 11 were isolated from the genus Dalbergia for the first time,and compounds 2,4-6,8,14 and 15 were isolated from the D. latifolia for the first time. Ten neoflavonoids were both discovered from D. latifolia and D. odorifera.
