    Analysis and Evaluation of Fatty Acid in Rattan Tea by Highly Selective and Sensitive HPLC- FLD-MS Method Coupled with Pre-Column Fluorescent Labeling
    摘要:
    藤椰茶作为预防和治疗许多慢性疾病的最有前景的膳食补充剂之一,受到广泛关注。游离脂肪酸在人体中作为必需营养素起着重要作用。首次使用对甲苯磺酸2-(萘-1-基-苯氨基)-乙基酯作为前柱荧光衍生化试剂,利用高效液相色谱-大气化学电离质谱(APCI/MS)技术,研究了藤椰茶中31种游离脂肪酸的含量。结果表明,低的检出限(0.52-1.53 ng mL-1)为游离脂肪酸的微量分析和评估提供了保障。实验的回收率在88.9%-103.6%之间。本研究的结果显示,藤椰茶中游离脂肪酸含量最高的月份是四月。共发现了13种游离脂肪酸,其中包括生命必需的C18:2w6、C18:3w3、w6和C20:4w6。所开发的方法展示了系统检测药用植物生物活性成分的强大潜力。

    amino acids for the stereospecificity. Recombinant EHA25900 oxidized 18:2n-6 sequentially to 9R-hydroperoxy-10(E),12(Z)-octadecadienoic acid (9R-HPODE) and to a 9R(10)-allene oxide. 9S- and 9R-DOX-AOS catalyze abstraction of the pro-R hydrogen at C-11, but the direction of oxygen insertion differs. A comparison between twelve 9-DOX domains of 9S- and 9R-DOX-AOS revealed conserved amino acid differences
