To study the distribution law of epigoitrin in roots of Isatis indigotica of different breed types and provide a scientific basis for screening of high-quality Isatis indigotica breed.
Determined the contents of epigoitrin in tap root and lateral root of Chinese-cabbage-leaf Isatis, cabbage-leaf Isatis, mustard-leaf Isatis and tetraploid Isatis by HPLC. Also, compared the contents of epigoitin in xylem and phloem of Isatis indigotica.
Contents of epigoitrin in the tap root and lateral root of Isatis indigotica of the different breed types were significant different. In four breed types of Isatis indigotica, contents of epigoitrin in the tap root and phloem were higher than those in the lateral root and xylem, respectively.
Contents of epigoitrin in the lateral root of Isatis indigotica are higher than those of tap root and epigoitrin distributes mainly in phloem.
研究不同品种类型菘蓝根中表告依春的分布规律，为筛选优质菘蓝品种提供科学依据。
采用高效液相色谱法测定大白菜叶型菘蓝、甘蓝叶型菘蓝、芥菜叶型菘蓝和四倍体菘蓝主根和侧根中表告依春的含量，并比较菘蓝木质部和韧皮部中表告依春的含量。
不同品种类型菘蓝主根和侧根中表告依春的含量差异显著。在四种菘蓝品种类型中，主根和韧皮部中表告依春的含量分别高于侧根和木质部。
菘蓝侧根中表告依春的含量高于主根，且表告依春主要分布在韧皮部。
