在优化的实验条件下，大规模分离纯化得到了菊苣酸含量为28%的产品。

Under the optimum conditions , the content of cichoric acid in product comes up to28 % . 3 .

为此，我们对根进行了离体培养研究，以期从中获得高含量的菊苣酸。

Therefore , we study culture of root in vitro , with a view to gain high level of cichoric acid .

我们对紫锥菊的各用药部位，叶片、叶柄、根、全草进行菊苣酸含量比较，发现紫锥菊根中菊苣酸含量最高。

We analyzed content of cichoric acid which from leaf , petiole , root and the whole plant , and found that of root is highest .

方法：用薄层色谱法鉴别甘草、桔梗、紫花松果菊，用高效液相色谱法测定甘草酸和菊苣酸的含量。

Method : Glycyrrhiza uralensis , Platycodon grandiflorum and Echinaceae purpurea were identified by TLC , and the content of Glycyrrhizic acid and Cichoric acid were determined by HPLC .

具有免疫活性的菊苣酸是紫锥菊制品质量控制的主要标准之一，紫锥菊可通过刺激机体的免疫系统而增强机体对细菌和病毒感染的抵抗力，具有抗生素样作用。

Cichoric acid is one of the main standards for the quality of Echinacea purpurea . It can stimulate the immune system and strengthen the resistance against bacterial and viral infection with antibiotic-like effect .

目前，由于缺乏简单、有效的方法大规模制备高含量的菊苣酸，所以，国内市场上仅有低含量的菊苣酸销售。

Currently , there is only low content of cichoric acid on sale in the market of China . For the lack of a simple and efficient approach to produce highly purified cichoric acid in large quantities .

本研究以紫锥菊种子为材料获得试管苗，再以试管苗的根为外植体直接诱导产生不定根，并对影响不定根生长和菊苣酸含量的一些因素进行了系统的考察。

In this study , we acquire test-tube plantlets with Echinacea purpurea seeds in vitro , roots from which were induced to adventitious roots directly . Effects of different physical and chemical factors on adventitious root culture and content of cichoric acid were investigated .
