Distribution of polyisoprenoids in various tissues of Bintaro (Cerbera manghas)

Bintaro (Cerbera manghas L, Apocynaceae) is a mangrove plant that has been described to have several important biological properties and pharmacological activities. In this study, the vegetative organs (leaves, roots, and stems) and the generative tissues (flowers and fruits) were analysed using two-plate thin layer chromatography to investigate the polyisoprenoid (polyprenol or dehydrodolichol and dolichol) profiles. It was found that in the vegetative tissues, there was two types (I and II) of polyprenols and dolichols detected. Type-I having a prevalence of dolichols over dehydrodolichols, was traced in the roots and stems, and type-II, having an occurrence of both polyprenols and dolichols, was found in the leaves. In contrast, in the generative organs only type-I was detected. Taken together, four out of five tissues tested showed a predominance of dolichols over polyprenols, suggesting the existence of polyprenol reductase in C. manghas. The varying polyisoprenoids in the different tissues of C. manghas indicating that these compounds have chemotaxonomic significance in C. manghas.Bintaro (Cerbera manghas L, Apocynaceae) is a mangrove plant that has been described to have several important biological properties and pharmacological activities.
