| 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 compound[quercetin 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. |
