摘　　要：对甜茶素加工副产物进行成分分析及活性研究,分析加工副产物中的甜茶素、总黄酮以及总酚含量,并测定甜茶素纯品以及副产物的抗氧化、抗过敏活性,抗氧化活性评价指标为:还原能力、OH.自由基及DPPH.自由基清除能力,抗过敏活性评价指标为:透明质酸酶抑制能力。结果表明:甜茶素加工副产物具有强抗氧化、抗过敏活性,其总酚含量达75.34%,回收率52.48%,不含甜茶素;SPSS相关性分析表明,甜茶的抗氧化、抗过敏活性与副产物中多酚含量存在极显著相关性,与甜茶素含量无显著相关性。The contents of rubusoside, total flavonoid and total phenol from rubusoside by-product have been analyzed. Antioxidant activity of rubusoside standard and its by-product was determined in terms of reducing power and scavenging acticity of· DPPH and. OH, anti-allergy activity was determined by Elson-Morgan. The result shows thai： by-product containing total phenol 75.34 %, the recovery rate is 52.48 %, which have high antioxidant and antiallergic activity. Antioxidant and anti-allergic capacity of sweet tea have significant correlation with the content of total phenol from by-product, which have no significant correlation with the content of rubusoside.
