The antioxidant activities of various extracts (methanol, hexane, dichloro-methane, ethyl acetate, n-butanol water) of Rhus typhina fruits and leaves were investigated using different methods and the main phenolic compounds were analyzed by LC-MS. The ethyl acetate extracts from fruits and leaves of R. typhina exhibited the highest DPPH, hydroxyl radical and nitrite scavenging activity, reducing potential and protein protection ability. The phenolic and flavonoïd contents were highest in the ethyl acetate fraction. The LC-MS analysis showed that the contents of luteolin and luteolin-7-O-glucuronide in leaves are little higher (34.49 and 32.69%, respectively) than that (32.49 and 27.89%, respectively) in the fruits, the content of rutin in fruits (16.73%) is higher than that (7.79%) in the leaves. These results implied that the leaves of R. typhina might serve as a natural source of antioxidant using as the food additive for its good nutrition as well as the fruits of Rhus typhina.
Key words: Antioxidant, free radical scavenging ability, LC-MS, Rhus typhina fruits and leaves, , ,
