摘要
以38%vol芦荟白酒为实验材料,对其功能性成分芦荟多糖、芦荟多酚、芦荟大黄素、维生素C和氨基酸进行了全面检测与分析。通过金属螯合力、羟基自由基清除力、超氧阴离子自由基清除力对芦荟白酒的体外抗氧化效果进行了评价。结果表明,芦荟白酒中芦荟多糖的含量高达(523.24±14.95)μg/mL,同时还含有氨基酸(63.4±4.3)μg/mL、维生素C(42.2±5.1)μg/mL和芦荟多酚(4.67±0.10)μg/mL等功能性成分,芦荟大黄素则未检出。研究表明,芦荟白酒具有较强金属鳌和能力、羟基自由基清除能力和一定程度的超氧阴离子自由基清除能力,且抗氧化能力与功能性成分的含量存在明显的量效关系。
The functional ingredients of aloe-polysaccharide, aloe-polyphenol, aloe-emodin, vitamin C and amino acids in 38%vol aloe liquor were measured. Meanwhile, the in vitro antioxidant activity of aloe liquor was evaluated by metal chelating ability, hydroxyl radical scavenging ability and superoxide anion radical scavenging ability. The result showed that the polysaccharide in aloe liquor reached up to （523.24±14.95） μg/ml, and the content of other functional components, such as amino acid, vitamin C in aloe liquor was （63.4±4.3） μg/ml, （42.2±5.1） μg/ml and （4.67±0.10） μg/ml, respectively. But aloe emodin was not detected. Aloe liquor showed strong metal chelating capability, hydroxyl radical scavenging capacity and a cer- tain degree of superoxide anion radical scavenging capacity. There were obvious dose-effect relationship between antioxidant capacity and the con- tent of functional components.
