摘要
在竹叶及其提取物中检出了一种特殊的非蛋白氨基酸δ－ＯＨ－Ｌｙｓ，为了解其生物学意义，用化学发光法和电子自旋共振法（ＥＳＲ）对δ－ＯＨ－Ｌｙｓ和Ｌｙｓ清除超氧阴离子自由基（Ｏ２－）的能力作了比较，结果表明赖氨酸在δ位羟化以后，抗活性氧自由基的活性有了显著提高。
A kind of specific non protein amino acid,δ OH Lys ,was detected out both from bamboo leaves and their extracts. Its biologic significance of antioxidation was investigated by Chemiluminescence and ESR. The results showed that the scavenging capacity of this hydroxyl lysine on O · 2 - was much stronger than lysine.
