Abstract

After the pandemic of COVID-19, there has been a growing interest in food safety concerns. Besides consuming wild-type animals, another focus is the synthetic compounds used in food preparation. Various reports show that antioxidant mechanisms might be closely related to decreasing the risk of disease infection. On 18 March 2020, Malaysia had the first Movement Control Order (MCO) that all communities must stay home. Public also questions whether natural food, mainly traditional Chinese medicine, can act as an antioxidant agent. Therefore, spectrophotometric procedures for determining the antioxidant capacities of selected samples were conducted. This method is based on scavenging 2, 2 diphenyl 1-picryl hydroxyl (DPPH) by adding a radical species or an antioxidant that decolourises the DPPH solution. This study aimed to compare, using the DPPH assay, the antioxidant level of Kappaphycus alvarezii to other traditional Chinese medicines (TCM) such as Andrographis paniculata, Lycium chinense and Ziziphus jujube. This study characterises the antioxidant activity of traditional Chinese medicines associated with carotenoid and total chlorophyll content from seaweed. Antioxidant analysis has shown that the highest antioxidant property was observed in the solvent extract of L. chinense. The DPPH assay provides an easy and rapid way to evaluate potential antioxidants in selected samples.
测定阿尔瓦雷斯海藻的抗氧化活性、叶绿素和类胡萝卜素含量:海藻与传统中药的比较
COVID-19 大流行之后,人们对食品安全问题的关注与日俱增。除了食用野生动物外,另一个关注点是食品制作过程中使用的合成化合物。各种报告显示,抗氧化机制可能与降低疾病感染风险密切相关。2020 年 3 月 18 日,马来西亚发布了首个 "运动控制令"(MCO),要求所有社区必须留在家中。公众还质疑以中药为主的天然食品是否能起到抗氧化剂的作用。因此,研究人员采用分光光度法测定了部分样本的抗氧化能力。这种方法是通过加入能使 DPPH 溶液脱色的自由基或抗氧化剂来清除 2,2-二苯基-1-吡啶羟基(DPPH)。本研究的目的是利用 DPPH 法,比较白花蛇舌草与穿心莲、枸杞子和酸枣仁等其他传统中药的抗氧化水平。本研究分析了与海藻中类胡萝卜素和总叶绿素含量相关的中药抗氧化活性。抗氧化分析表明,枸杞的溶剂提取物具有最高的抗氧化性。DPPH 分析法为评估所选样品中潜在的抗氧化剂提供了一种简便、快速的方法。
