芒鸡脚参(Orthosiphon aristatus)是来源于南亚的药用植物,具有利尿活性。作者分析了芒鸡脚参不同部位苯丙素类(phenylpropanoids)成分的分布,结果表明二种咖啡酸酯和黄酮在花中含量最高。例如主要成分迷迭香酸(rosmarinic acid)在鲜花中含量超过16gmol/g,其中花萼和花托中含量最高,可达20μmol/g,新鲜叶和茎中含量仅为0.8/μmol/g。植物根和地上部分皆含有全类型的咖啡酸酯。新鲜植物根中咖啡酸衍生物的含量比茎和叶中高(如迷迭香酸含量为2μmol/g)。根不含黄酮类化合物。从芒鸡脚参每个部位都分离出新的
Orthosiphon aristatus is a medicinal plant from South Asia that has diuretic activity. The authors analyzed the distribution of phenylpropanoids in different parts of Mangzi foot ginseng. The results showed that the contents of the two caffeic acid esters and flavonoids were highest in flowers. For example, the main component of rosmarinic acid is more than 16gmol/g in flowers, and the highest content in flowers and torus is 20μmol/g, and the content in fresh leaves and stems is only 0.8/μmol/g. Plant roots and above-ground parts contain all types of caffeic acid esters. The content of caffeic acid derivatives in the roots of fresh plants was higher than in stems and leaves (eg, rosmarinic acid content was 2 μmol/g). The root contains no flavonoids.
