用高效液相色谱法研究了含有原生质体的豆胚叶中叶绿素a(Chl)形成过程中叶绿素内酯(Chlide)的不同酯类化合物的变化规律。在将光活性香叶素(Pchlide)还原为Chlide后，在Chlide植物醇形成之前，还检测到了Chlide香叶醇、Chlide二氢香叶醇和Chlide四氢香叶醇三种中间体，即正品Chl。在含有原生质体的叶片中，Chlide转化为Chl的速度比含有黄体的叶片要快得多。
The time course of the different esters of chlorophyllide (Chlide) during the formation of chlorophyll a (Chl) in embryonic bean leaves containing proplastids was investigated by HPLC. After the reduction of photoactive Pchlide (Pchlide) to Chlide, three intermediates, i.e. Chlide geranylgeraniol, Chlide dihydrogeranylgeraniol and Chlide tetrahydrogeranylgeraniol were detected before the formation of Chlide phytol, i.e. authentic Chl. The transformation of Chlide to Chl was found to be much faster in leaves containing proplastids than in etiolated leaves with etioplasts.
