The objective of this study was to investigate antioxidant and anti-inflammatory activity of cabbage phytochemicals.
Color coordinates were evaluated by colorimetry, and the antioxidant and anti-inflammatory activities were analyzed by spectrophotometer for some common cabbage varieties.
Red heads had the highest total antioxidant contents followed by Savoy, Chinese and green heads. The Chinese variety had the highest ABTS (2,2-azino-di-(3-ethylbenzthiazoline-sulfonic acid) antioxidant activity, was 5.72 μmol TE/g fw (Trolox equivalent). The green variety had the highest DPPH (free radical scavenging activity) antioxidant activity, which was 91.2 μmol TE/g fw. The red variety had the highest FRAP (ferric reducing antioxidant power) antioxidant activity, which was 80.8 μmol TE/g fw. The total phenol amounts were 17.2-32.6 mM trolox equivalent antioxidant capacity (TEAC) and the total flavonoid amounts were 40.0-74.2 mg quercetin per gram. Methanolic extracts of different cabbage heads showed different anti-inflammatory activity values. Chinese, Savoy and green heads had the highest anti-inflammatory activity, while red heads had the lowest.
The results suggest that these varieties of cabbage heads could contribute as sources of important antioxidant and anti-inflammatory related to the prevention of chronic diseases associated to oxidative stress, such as in cancer and coronary artery disease.
本研究的目的是调查甘蓝植物化学物质的抗氧化和抗炎活性。
通过比色法评估颜色坐标，并使用分光光度计分析一些常见甘蓝品种的抗氧化和抗炎活性。
紫甘蓝的总抗氧化剂含量最高，其次是皱叶甘蓝、中国甘蓝和绿甘蓝。中国甘蓝品种的ABTS（2,2-联氮-二（3-乙基苯并噻唑啉-6-磺酸））抗氧化活性最高，为5.72 μmol TE/g fw（Trolox当量）。绿甘蓝品种的DPPH（自由基清除活性）抗氧化活性最高，为91.2 μmol TE/g fw。紫甘蓝品种的FRAP（铁还原抗氧化能力）抗氧化活性最高，为80.8 μmol TE/g fw。总酚含量为17.2 - 32.6 mM trolox当量抗氧化能力（TEAC），总黄酮含量为每克40.0 - 74.2 mg槲皮素。不同甘蓝头的甲醇提取物显示出不同的抗炎活性值。中国甘蓝、皱叶甘蓝和绿甘蓝的抗炎活性最高，而紫甘蓝的抗炎活性最低。
结果表明，这些甘蓝品种可作为重要抗氧化剂和抗炎剂的来源有助于预防与氧化应激相关的慢性疾病，如癌症和冠状动脉疾病。
