姜黄叶水蒸馏精油的化学成分。通过GC-MS进行分析。鉴定出 23 种化合物，占总油量的 94.29%。使用 2,2-二苯基-1-三硝基苯肼 (DPPH) 和超氧自由基清除测定法评估了芳香茶油和各种提取物的抗氧化活性。油和甲醇提取物显示出有效的DPPH自由基清除活性（IC50分别为14.45和16.58μg/ml），高于丁基羟基苯甲醚（IC50=18.27μg/ml）。该提取物还表现出显着的超氧自由基清除活性（IC50=22.6-45.27μg/ml），并且甲醇提取物的活性优于所有其他提取物（IC50=22.6μg/ml）。此外，测定了总酚化合物的量，与其他提取物相比，乙酸乙酯提取物中其含量最高。结果表明，芳香茶的油和提取物可以作为食品工业中使用的重要抗氧化剂生物资源。 (C) 2010 Elsevier Ltd. 保留所有权利。
The chemical composition of the hydro-distilled essential oil from leaves of Curcuma aromatica Salisb. was analysed by GC-MS. Twenty-three compounds representing 94.29% of the total oil were identified. The antioxidant activities of the oil and various extracts of C. aromatica were evaluated by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide radical-scavenging assays. The oil and methanol extract showed potent DPPH radical-scavenging activities (IC50 = 14.45 and 16.58 mu g/ml, respectively), which were higher than butylated hydroxyanisole (IC50 = 18.27 mu g/ml). The extracts also exhibited remarkable superoxide radical-scavenging activities (IC50 = 22.6-45.27 mu g/ml) and the activity in the methanol extract was superior to all other extracts (IC50 = 22.6 mu g/ml). Furthermore, the amount of total phenolic compounds was determined and its content in ethyl acetate extract was the highest as compared to other extracts. The results indicate that the oil and extracts of C. aromatica could serve as an important bio-resource of antioxidants for using in the food industries. (C) 2010 Elsevier Ltd. All rights reserved.
