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.
降香来源于降香檀的心材，降香檀是中国国家二级珍稀濒危保护植物。其资源稀缺，价格高昂。为寻找降香的替代品，采用硅胶、葡聚糖凝胶LH - 20柱色谱和半制备高效液相色谱法，对阔叶黄檀心材70%乙醇提取物的化学成分进行了系统研究。通过光谱数据分析和/或将光谱数据与文献中的数据进行比较，分离并鉴定出16种新黄酮类化合物，分别为8种降香酚（1 - 8）、3种降香酮（9 - 11）、2种降香素（12,13）、2种二苯甲酮（14,15）和1种其他类型的新黄酮类化合物（16）。其中，化合物3、7和11首次从黄檀属植物中分离得到，化合物2、4 - 6、8、14和15首次从阔叶黄檀中分离得到。从阔叶黄檀和降香檀中均发现了10种新黄酮类化合物。
