Analysis of polyisoprenoids in the leaves and roots of Aegiceras floridum and Lumnitzera littorea

Abstract

A. floridum and L. littorea are the members of significant mangroves which are abundant in Indonesia that has been reported to have biological properties. The pattern and existence of polyisoprenoid alcohols (polyprenols/dehydrodolichol and dolichols) inthe leaves and roots of A. floridum and L. littorea were investigated using a convenient two-plate thin layer chromatography method. The polyprenols and dolichols distribution was determined and classified into two groups. Group-I, having a dominating of dolichols over dehydrodolichols, was found in the roots of L. littorea with one dolichol family (C90-C95). Type-II, showing the existence of both dehydrodolichols and dolichols, was observed in the leaves A. floridum (with polyprenol and dolichol chain length C 60 -C 80 and C 90 -C 95 , respectively). Furthermore detected in leaves of L. Littorea, polyprenol and dolichol occurred longer chain length (C 60 -C 140 and C 70 -C 140 , respectively) and roots of A. floridum with a chain length of dolichol (C 75 -C 100 ) few longer that polyprenol (C85-C95). The composition of polyisoprenoids in leaves and roots tissues of A. floridum and L. littorea is the first description to extend our previous finding on the occurrence polyisoprenoids in mangrove plants.
