Abstract

This study aims to determine the ratio of turmeric rhizome extract (TE) and tamarind leaf extract (TLE), which is suitable for the time of induction and the highest antioxidant synergism. The TE:TLE ratio examined was 10:1; 10:1.5 and 10:2. The chosen variable was the amount of peroxide. Observations carried out for 7 hours at one-hour intervals using ferric thiocyanate (FTC) method and thiobarbituric acid (TBA) method. Relationship between the time and absorbance were depicted to show the induction time and synergism in antioxidants. The results showed that all TE and TLE ratios had antioxidants that inhibited lipid oxidation reactions at the stage of initiation and propagation. TE and TLE ratios 10:1, 10:1.5 and 10:2 had induction time, respectively 2.9577; 3.0206 and 3.1882 hours with FTC method, 3.6116; 3.706 and 3.8722 h with the TBA method. Synergism in antioxidants was 103.534; 106.924 and 110.705 % with the FTC method, and 102.9393; 109.522 and 115.969 % with TBA. The highest antioxidant synergism in both methods was shown by the ratio of TE:TLE = 10:2. Key word: Turmeric, tamarind leaves, induction time, synergism antioxidant

姜黄和罗望子叶提取物比例与诱导时间和抗氧化活性协同作用的关系

本研究旨在确定姜黄根茎提取物（TE）和罗望子叶提取物（TLE）的比例，该比例适合诱导时间和最高的抗氧化协同作用。TE与TLE的比值为10:1；10:1.5和10:2。选择的变量是过氧化物的量。使用硫氰酸铁（FTC）法和硫代巴比妥酸（TBA）法每隔一小时进行7小时的观察。时间和吸光度之间的关系显示了抗氧化剂的诱导时间和协同作用。结果表明，所有TE和TLE比例在起始和繁殖阶段都具有抑制脂质氧化反应的抗氧化剂。TE和TLE比值分别为10:1、10:1.5和10:2，诱导时间分别为2.9577；FTC法分别为3.0206和3.1882小时，3.6116；3.706和3.8722小时。抗氧化剂的协同作用为103.534；FTC法分别为106.924和110.705%，102.9393；TBA分别为109.522和115.969%。两种方法中抗氧化协同作用最高的是TE:TLE=10:2。关键词：姜黄、罗望子叶、诱导时间、协同抗氧化
