Distribution of polyprenols and dolichols from fruits and rinds of Barringtonia racemosa, Thespesia populnea, and Xylocarpus granatum

This present study describes the distribution and pattern of polyprenols and dolichols from fruits and rinds of selected mangrove plants namely Barringtonia racemosa, Thespesia populnea, and Xylocarpus granatum that were analysed using two-plate thin layer chromatography (2P-TLC) method. In the fruits and rinds organs, two-types the pattern of polyprenols and dolichols were obtained. Type-I, having the prevalence of dolichols over polyprenols, was detected in fruits of B. racemosa and X. granatum fruits and rinds. Type-II, the occurrence of both polyprenols and dolichols, was traced in fruits and rinds of T. populnea and rinds of B. racemosa. In all tissues of fruits and rinds of B. racemosa, T. populnea, and X. granatum were occurred chain length of dolichol (C₅₀-C₁₁₀, C₆₀-C₁₁₀), (C₆₅-C₁₀₀, C₈₀-C₉₅), and (C₈₀-C₉₀, C₈₀-C₉₀), respectively. Whereas the polyprenol occurred only in fruits and rinds of T. Populnea (C₆₅-C₉₀, C₅₅-C₆₅), and B. racemosa rinds (C₆₀-C₁₁₀). The composition of polyisoprenoid in fruits as well as rinds of B. racemosa, T. populnea, and X. granatum is first study to extend our previous finding of the profile and characterization of polyisoprenoid in mangrove plants.
