| 摘 要： | 以活性追踪为指导分离和纯化了月季花中具有1,1-二苯基-2-三硝基苯肼(DPPH)自由基清除活性的成分. 从月季花中分离得到了10个黄酮类化合物, 采用光谱法对其结构进行了表征, 并对它们的自由基清除活性进行了评价. 结果表明, 化合物1为新化合物, 化合物1, 2, 4和9具有较强的清除DPPH自由基的活性.

| Abstract: | In order to separate and purify the chemical constituents from Rosa chinensis Jacq., which have DPPH· scavenging capacity, dried Rosa chinensis flowers were extracted three times with 95% ethanol under reflux. This extract was then fractionated by column chromatography over silica gel, MCI gel, Sephadex LH-20, etc. A new compoundquercetin 3-O-(2",6"-digalloyl)-β-D-glucoside, 1] and nine known compounds (2-10) were isolated from Rosa chinensis Jacq. and identified using spectroscopic methods. Their antioxidant activity was assayed using DPPH· experiments. The results indicated that compounds 1, 2, 4 and 9 had good antioxidant activity. |
