摘要:

研究红果樫木叶的化学成分, 运用大孔树脂、硅胶、Sephadex LH-20和半制备色谱等多种色谱技术从红果樫木叶70%乙醇提取物中分离得到4个木脂素类化合物。运用1H NMR(核磁共振)、13C NMR和MS(质谱)波谱学数据等分别鉴定为4, 4'-dihydroxy-3, 3', 5, 5'-trtramethoxy-7, 9':7', 9-diepoxylignane(1), 4'-hydroxy-3, 4, 5, 3'-trtramethoxy-7, 9':7', 9-diepoxylignane(2), 4', 4″-dihydroxy-3, 3', 3″, 5, 5', 5″ -hexamethoxy-7, 9':7', 9-diepoxy-4, 8″-oxy-8, 8'-sesquineolignan-7″, 9″-diol(3)和4', 4″-dihydroxy-3, 3', 3″, 5, 5'-pentamethoxy-7, 9':7', 9-diepoxy-4, 8″-oxy-8, 8'-sesquineolignan-7″, 9″-diol(4)。化合物1~4均首次从樫木属植物中分离得到。使用DPPH(1, 1-二苯基-2-三硝基苯肼)自由基清除率测定化合物的抗氧化活性, 结果显示木脂素类化合物1~4具有良好的DPPH自由基清除能力。

Abstract:

To study the constituents of the leaves of Dysoxylum gotadhora, the 70% ethanol extract was separated using macroporous resin column chromatography, silica gel column chromatography, Sephadex LH-20 gel column chromatography, combined with semi-preparative HPLC and other methods. Four compounds 4,4'-dihydroxy-3,3',5,5'-trtramethoxy-7,9':7',9-diepoxylignane (1), 4'-hydroxy-3,4,5,3'-trtramethoxy-7,9':7',9-diepoxylignane (2), 4',4″-dihydroxy-3,3',3″,5,5',5″ -hexamethoxy-7,9':7',9-diepoxy-4,8″-oxy-8,8'-sesquineolignan-7″,9″-diol (3), 4',4″-dihydroxy-3,3',3″,5,5'-pentamethoxy-7,9':7',9-diepoxy-4,8″-oxy-8,8'-sesquineo lignan -7″,9″-diol (4) were isolated. Their structures were established by 1H NMR, 13C NMR and MS spectroscopy techniques. Compounds 1 to 4 were obtained from the genus Dysoxylum for the first time. DPPH(1,1-diphenyl-2-picryhydrazyl radical 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl) radical scavenging rate were used to determine the antioxidant activity. The results show that lignans have significant DPPH free radical scavenging ability.

Key words: Dysoxylum gotadhora, chemical constituents, structure identification
