摘　　要：以牡丹雄蕊为材料,研究了不同溶剂提取物的抗氧化活性,并对其酚类成分进行分析。分别选择水、70%甲醇、70%乙醇、50%丙酮作为提取溶剂,测定提取物的DPPH自由基清除能力、总黄酮和总酚含量,对酚类组分进行了分析。结果表明,70%的甲醇提取物具有良好的抗氧化能力,没食子酸、芦丁、槲皮素是其中的主要酚类成分。研究为牡丹雄蕊资源的开发提供了一定的参考。Antioxidant activity and phenolic compounds in different solvent extracts of peony stamens were studied in the present study. Solvents, sucha as water, 70% methanol, 70% ethanol, and 50% acetone was employed as extraction solvent, and DPPH radical scavenging capacity, total flavones, total phenolic content were compared and analyzed. Result showed that the extract from 70% methanol had the better antioxidant activity than that of other solvents. In addition, gallic acid, rutin and quercetin were of the main phenolic compounds in peony stamen. These results provided an instruction for the development of peony stamens resources.
