【摘要】 利用硅胶柱色谱、凝胶柱色谱、MCI柱色谱对红光树属植物红光树枝叶的70%丙酮提取物进行分离纯化,并通过¹H NMR、¹³C NMR等波谱技术进行结构鉴定,共分离鉴定了14个黄酮类化合物。分别为pinocembrin （1）、eriodictyol （2）、naringenin （3）、dihydroquercetin （4）、dihydrokaempferol（5）、5,7,3′,4′-tetrahydroxy-3-methoxyflavone（6）、quercetin（7）、luteolin（8）、（-）-epicatechin（9）、biochanin A（10）、tectorigenin（11）,2′,5,7-trihydroxy-4′-metoxyisoflavone（12）、5,7-dihydroxychromone（13）、7-hydroxychromone（14）。除了化合物4和10,其余12个化合物均首次从红光树属植物中分离得到。更多还原

【Abstract】 This research focused on the chemical constituents of Knema furfuracea. From the 70% acetone extract, fourteen flavonoids were separated and purified by the column chromatography. By means of spectroscopic analysis, the compounds were identified as pinocembrin(1), eriodictyol(2), naringenin(3), dihydroquercetin(4), dihydrokaempferol(5), 5,7,3’,4’-tetrahydroxy-3-methoxyflavone(6), quercetin(7), luteolin(8),(-)-epicatechin(9), biochanin A(10), tectorigenin(11), 2’,5,7-trihydroxy-4’-metoxyisoflavone(12), 5,7-dihydroxychromone(13), and 7-hydroxychromone(14). The 12 compounds were isolated from Knema furfuracea leaves for the first time, with compound( 4) and(10) excluded.更多还原
