为探明长春花叶片中生物碱的动态变化和生物碱合成途径中的关键酶基因的表达量,利用高效液相色谱技术(HPLC)测定了5对真叶期、开花前期、出现花蕾期、出现开花期、成熟期1和成熟期2等6个生长阶段的长春花幼嫩、中等成熟、成熟三种叶片的生物碱(文多灵、长春质碱、长春碱)的含量.幼嫩叶片中文多灵、长春质碱和成熟叶片中长春碱的含量...
In order to clarify the dynamic change of three alkaloids(TIAs including vindoline,catharanthine and vinblastine) and the expression of the associated biosynthetic genes in the Catharathus Roseus leaves(young,medium and old) at different growing stages,high performance liquid chromatography was applied to determine the contents of TIAs at the leaf period,pre-floweringperiod,bud stage,flowering period,fully-mature period 1 and fully-mature period 2 in five pairs of leaves from Catharathus Roseus.In addition,...
