摘要

目的:研究泽兰花地上部位的抗氧化成分。方法:采用多种色谱技术对白花苜蓿乙醇提取物进行分离纯化。根据各种光谱数据，对分离化合物的结构进行了分析。对分离得到的化合物进行ABTS+自由基清除的抗氧化活性评价。结果:共分离得到11个化合物，分别为顺式异辛诺酮-4- o -β- d -葡萄糖苷(1)、桃核苷(2)、2,6-二甲氧基对对苯二酚-1- o -β- d -葡萄糖苷(3)、3-(β- d -葡萄糖苷)-4-甲氧基苯甲酸(4)、3 ' - o -β- d -葡萄糖苷-葡萄糖苷甲酯(5)、3 ' - o -β- d -葡萄糖苷-葡萄糖苷甲酯(6)、铅柏酸(7)、铅柏碱A(8)、铅柏碱C(9)、丁香-4- o -β- d -葡萄糖苷甲酯(10)和2-甲基-5-羟色酮(11)。化合物2、3、5对ABTS+具有明显的清除作用。结论:化合物1 ~ 4、10、11为首次从该植物中分离得到。化合物2、3和5具有显著的抗氧化作用。

[Chemical Constituents of the Aerial Parts from Plumbago zeylanica].

Objective: To study the anti-oxidative constituents of the aerial parts of Plumbago zeylanica.

Methods: The ethanol extract of Plumbago zeylanica was separated and purified by various chromatographic techniques. On the basis of various spectroscopic data, the structures of isolated compounds were elucidated. ABTS+radical scavenging were carried out in antioxidant activity evaluation of the isolated compounds.

Results: Eleven compounds were isolated and identified as cis-isoshinanolone-4-O-β-D-glucopyranoside( 1),tachioside( 2),2,6-dimethoxy-p-hydroquinone-1-O-β-D-glucopyranoside( 3),3-( β-D-glucopyranosyloxy)-4-methoxybenzoic acid( 4),3’-O-β-D-glucopyranosyloxy-plumbagic acid( 5),3’-O-β-D-glucopyranosyloxy-plumbagic acid methyl ester( 6),plumbagic acid( 7),plumbagine A( 8),plumbagine C( 9),syringate-4-O-β-D-glucopyranoside( 10) and 2-methyl-5-hydroxychromone( 11). Compounds 2,3,and5 displayed significant scavenging effect on ABTS+.

Conclusion: Compounds 1 ~ 4,10,11 are obtained from this plant for the first time. Compounds 2,3,and 5 show significant anti-oxidative effects.
