摘　　要：为研究不同品种山楂不同组织部位的抗氧化成分及活性,该文以3种山楂属果实(大山楂、小山楂和山里红)为原料,通过测定不同组织部位的总酚、总黄酮、原花青素以及单宁含量和抗氧化活性指标(DPPH自由基、ABTS阳离子自由基清除能力以及还原能力),综合评价山楂属果实的抗氧化性能。结果表明,3种山楂果实的果皮具有较高的总酚、总黄酮、原花青素以及单宁含量,并且具有较强的抗氧化活性;大山楂和小山楂果皮和果肉含有较高的总酚、总黄酮含量,并且表现出了较强的抗氧化活性;山楂属果实不同组织中总酚、总黄酮含量与抗氧化活性之间呈现极显著的正相关关系。因此,山楂果皮和果肉可作为天然抗氧化物质的潜在来源,应用前景广泛。To analyze the antioxidant components and activities of different tissue in varieties of hawthorn,three hawthorn varieties were characterized concerning for their antioxidant capacities and antioxidant compounds such as phenolic,flavonoid,tannin and anthocyanin.Antioxidant capacity was measured using the DPPH,ABTS and reducing power assays.The results showed that the peel of all cultivars had the best antioxidant capacities,reflected the highest content of total phenolics,flavonoids,and anthocyanins found in this part.The peel and pulp of big hawthorn and small hawthorn contained higher total phenolics and total flavonoids.There were positive significant correlations be-tween the total phenolics,total flavonoids and antioxidant activity in different tissues of hawthorn fruits.The results obtained in this study in-dicated that the peel and pulp of hawthorn had a potential to be used as a natural antioxidant agent.
