中文摘要 | 高雄區農業改良場旗南分場自1988年7月設置有機試驗田至今已逾20年,而毗鄰之有機試驗田也逾7年。由於國內對有機蔬菜抗氧化能力方面研究成果較少,本試驗即以此20年及7年長期有機試驗田2008年秋作的小果番茄與甘藍及2009年春作的甜玉米為研究對象,分析其抗氧化能力與抗氧化物質含量,並與折衷區、慣行區之分析資料進行比較。2008年秋作之清除DPPH自由基能力分析結果顯示,甘藍僅輪作系統1(R1)之7年有機區顯著優於慣行區。小果番茄則以7年及20年有機區之「聖運」和「金玉」兩品種均顯著優於慣行區。氧自由基吸收能力(ORAC)分析結果呈現甘藍以R1之7年與20年有機區及輪作系統2(R2)之20年有機區表現最佳,與慣行區具顯著差異。小果番茄分析結果,有機區表現亦佳,與慣行區具顯著差異。總多酚含量方面,甘藍以R1之7年有機區總多酚含量最高,且與慣行區具顯著差異;小果番茄「聖運」以7年有機區表現顯著優於慣行區。大致上,有機區之總多酚含量均高於慣行區,然以統計分析結果來看,部份處理間之差異並不顯著。類胡蘿蔔素與茄紅素含量方面,小果番茄「聖運」各處理之兩物質含量均無顯著差異;而「金玉」分析結果,有機區表現略佳,但差異不顯著。2009春作甜玉米分析結果,在抗氧化力及總多酚含量方面,有機區則均無顯著優勢。作物種類或品種的差異以及其所含的抗氧化物質的數量對於抗氧化能力的強弱均具有相當程度的影響。 |
英文摘要 | A long-term experiment field of organic farming (OF) has been set at Chinan branch station of Kaohsiung District Agricultural Research and Extension Station (KDARES) since July 1988, and another organic field close to the long-term experiment field has also been set more than seven years. Owing to little information about anti-oxidative activity of organic vegetables published domestically, in this article, organic tomatoes and cabbages from autumn season 2008 and organic sweet corns from spring season 2009 were used to analyze the anti-oxidative activity and the content of anti-oxidative substances. Besides, vegetables from intermediate farming (IF) and conventional farming (CF) were used to be the control. In the result of anti-oxidative activity of DPPH (1, 1-diphenyl- 2-picrylhydrazyl) free radical scavenging effect, the 7-year organic cabbage of crop rotation system 1 (R1) and 20-year and 7-year organic tomatoes of both rotation system showed better than those of CF. In the result of oxygen radical absorbance capacity (ORAC), the organic cabbage and tomatoes were better than those of CF. The organic cabbage and tomatoes had higher amount in total poly-phenolic content, but only the 7-year organic treatment showed obvious difference. The Organic tomatoes were not obviously better than those of CF in the analyses of β-carotene and lycopene. In the analysis on sweet corn, there was no obvious advantage in organic sweet corn corresponding to those of CF in the anti-oxidative activity of DPPH assay and ORAC and total poly-phenolic content. In the conclusion, both the sorts of crop and the amount of anti-oxidative substances would affect the anti-oxidative activity. |
