The specificity of two separate tonoplast permeases transporting oleanolic acid glycosides was investigated in vacuoles isolated from leaf protoplasts of marigold (Calendula officinalis) with the use of chemically synthesized analogs. The results indicate that the proper structure of both parts of oleanolic acid monoglycoside, i.e. aglycon and the sugar moiety, are required for binding to a specific tonoplast carrier.
利用化学合成类似物，在从金盏花（金盏菊）叶片原生质体分离的液泡中，研究了两种单独的液泡膜渗透酶转运齐墩果酸糖苷的特异性。结果表明，齐墩果酸单糖苷的两个部分，即苷元和糖部分的适当结构，是与特定液泡膜载体结合所必需的。
