摘　　要：探讨地肤全草及其分离纯化的阿魏酸衍生物的体外抗氧化活性。采用1,1-二苯基-2-苦味偕腙肼自由基(·DPPH)法、Fe3+还原力测定试验,通过与维生素C和水杨酸对照,考察地肤子、叶和根茎以及从地肤分离纯化的阿魏酸衍生物的抗氧化活性。地肤叶和根茎提取物的抗氧化活性略弱于地肤子提取物,分离出的两种阿魏酸衍生物的抗氧化活性略低于维生素C的活性,明显高于水杨酸的抗氧化活性。地肤全草及从地肤分离纯化的阿魏酸衍生物均具有良好的抗氧化活性,具有潜在的开发利用价值。The present study was to investigate the antioxidant activity of the whole herbs of Kochia scoparia and theirs ferulic acid derivatives in vitro through 1,1-diphenyl-2-picryhydrazyl free radical（DPPH·） and Fe3＋reduction ability experiments. The antioxidant activity of extracts and ferulic acid derivatives were also compared with vitamin C and salicylic acid. The results showed that the antioxidant activity of extracts from the whole herbs of Kochia scoparia was slightly weaker than that of extracts from the fruits of Kochia scoparia,while the antioxidant activity of N-trans-feruloylmethoxytyramine and N-trans-feruloyltyramine which isolated from Kochia scoparia were slightly weaker than that of vitamin C but better than salicylic acid.It was concluded that the whole herbs of Kochia scoparia and ferulic acid derivatives had preferable antioxidant activity in vitro,which provided the theory basis for the further development of the whole herbs of Kochia scoparia and ferulic acid derivatives.
