Objective: To study the antioxidant activity part and chemical components from Rosa roxburghii fruit. Method: The free radical scavenging capacity in different parts of R. roxburghii fruit was tested and evaluated by DPPH method. The chemical components in antioxidant activity parts were isolated and purified by silica gel column chromatography
gel column choromatography and high performance liquid chromatography (HPLC). Their structures were identified by analysis of physical and spectral data. Result: The results showed that the ethyl acetate extracts had better DPPH radical-scavenging capacity than positive control ascorbic acid. Five compounds were isolated from this antioxidant activity part:kaji-ichigoside (1)
euscaphic acid (2)
rosamultin (3)
arjunetin (4)
1-β hydroxyl euscaphic acid (5)
respectively. Conclusion: Compounds 4 and 5 were isolated from the plant for the first time.
