交趾黄檀心材的黄酮类和三萜类成分

Flavonoid and Triterpenoid Compounds from the Heartwood of Dalbergia cochinchinensis

摘要:

为研究交趾黄檀（Dalbergia cochinchinensis）的化学成分，采用有机溶剂提取、萃取及多种色谱分离技术，从其心材中分离得到5个新黄酮和7个其他类型成分。根据理化性质和波谱数据，其结构分别鉴定为：7-hydroxy-2'，3'，4'-trimethoxyisoflavan（1）、6，4'-dihydroxy-7-methoxyflavan（2）、R-dalbergiphenol（3）、R-4-methoxydalbergione（4）、mimosifoliol（5）、R-5-O-methyllatifolin（6）、R-latifolin（7）、maackiain（8）、secundiflorol Ι（9）、3，9-dimethoxy-6H-benzofufo[3，2-c]chromen-6-one（10）、mucodianin C（11）、lup-（20）29-ene-2α，3α-diol（12）。化合物1、5、8~12为首次从交趾黄檀植物中分离得到。

Abstract:

To investigate the chemical constituents of Dalbergia cochinchinensi, five neoflavonoids and seven other compounds were isolated from its heartwood by various methods, such as organic solvent extraction, fractionation and chromatographic separation techniques. Based on physical and chemical properties and spectral data, their structures were identified as 7-hydroxy-2',3',4'-trimethoxyisoflavan (1), 6,4'-dihydroxy-7-methoxy-flavan (2), R-dalbergiphenol (3), R-4-methoxydalbergione (4), mimosifoliol (5), R-5-O-methyllatifolin (6), R-latifolin (7), maackiain (8), secundiflorol Ι (9), 3,9-dimethoxy-6H-benzofufo[3,2-c]chromen-6-one (10), muco-dianin C (11), lup-(20)29-ene-2α,3α-diol (12). Compounds 1, 5 and 8-12 were isolated from D. cochinchinensi for the first time.
