两种生态型盐芥的芥子油苷比较

Comparison of glucosinolates in two Thellungiela salsuginea ecotypes

利用超效液相色谱系统在两种生态型盐芥—Shandong生态型(ecotype Shandong)和Xinjiang生态型(ecotype Xinjiang)中均检测到7种芥子油苷。幼苗时期,Shandong生态型的莲座叶的总芥子油苷含量显著高于Xinjiang生态型,成苗时期差异不显著,但组分中3MTP、I3M、4MOI3M、2PE的含量均是Shandong生态型显著高于Xinjiang生态型。两种生态型根的总芥子油苷含量差异不显著,但Shandong生态型根的3MSOP、Allyl含量显著高于Xinjiang生态型,而其I3M含量却显著低于Xinjiang生态型。

Seven glucosinolates in two Thellungiela salsuginea（ T. salsuginea） ecotypes（ ecotype Shandong and ecotype Xinjiang） were identified by ultra-performance liquid chromatography. The total content of glucosinolates in the leaves of ecotype Shandong was significantly higher than one of ecotype Xinjiang at the young vegetative stage whereas their difference became vague at the late vegetative stage.However,the content of 3MTP,I3 M,4MOI3M and 2PE in leaves of ecotype Shandong was significantly higher than one in ecotype Xinjiang at two different growth stages. The total contents of glucosinolates were similar in the roots of two T. salsuginea ecotypes,whereas the content of 3MSOP and Allyl in ecotype Shandong was significantly higher than one in ecotype Xinjiang and the content of I3 M in ecotype Xinjiang was significantly higher than the one in ecotype Shandong.
