本研究采用2，2-二苯基-1-苦基肼(DPPH)法测定了白头翁果实精油(EO)和不同提取物的总酚和类黄酮类化合物的含量及抗氧化活性。结果表明，脱臭提取物比脱臭提取物具有更强的抗氧化活性。甲醇提取物(IC50 = 36.7 µg·ml−1)对自由基的清除能力最强，而EO的清除活性最弱，其IC50 = 为3326.7 µg·ml−1。脱臭原料甲醇提取物的亚组分富含酚类和类黄酮类物质，其次是脱臭甲醇提取物和热水提取物。提取物的抗氧化活性与总酚和总黄酮类含量呈正相关。图形摘要
This study was designed to examine the total phenolic and flavonoid levels and the antioxidant activities of the essential oil (EO) and various extracts obtained from fruits of Ammodaucus leucotrichus using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. According to the results obtained, the odorized extracts exhibited stronger antioxidant activity than the desodorized extracts. The highest radical-scavenging activity was shown by the odorized water soluble (OdMW) of the methanol extract (IC50 = 36.7 µg.ml−1), whereas the EO showed the weakest activity potential with an IC50 = 3326.7 µg.ml−1. As well as the radical-scavenging activity of the extracts, they were evaluated in terms of their total phenolic and flavonoid contents. The subfractions of methanol extracts from odorized material were found to be rich in phenolics and flavonoids, followed by the subfractions of desodorized methanol extracts and the hot water extracts. Finally, a positive correlation was observed between the antioxidant activity and total phenolic and flavonoid levels of the extracts. GRAPHICAL ABSTRACT
