Polyprenol and Dolichol Content in the Seed Tissues of Elaeis guineensis Jacq. from Commercial Seeds

Abstract

Polyisoprenoid alcohols are found in the cells of all living organisms. This work aims to investigate their distribution in the seed tissues of oil palms in commercial and non-commercial companies using two-dimensional thin layer chromatography (2D-TLC). The distribution of dolichols and polyprenols found in oil palm plants varies depending on the region. There is no difference in the distribution of polysoprenoids between Socfin Indonesia (Socfindo) CI Ganoderma susceptible, Socfindo Lame, and Indonesian Oil Palm Research Institute (IOPRI) BSY2C seeds tissue (4.5 mg/g dry weight). The total polyprenol and dolichol in the seed tissues of oil palms from Socfindo MTG was higher than those from other oil palms: it was 6.1 mg/g dry weight and 4.7 mg/g dry weight, respectively. The highest polyisoprenoids concentration in the seed tissues of oil palms was found in those from Socfindo Yagambi. Polyprenol; longer chain lengths were observed in the oil palms of non-commercial (C75-C100) and dolichol of commercial seeds from IOPRI 05-73 (C70-C100). The seeds from Socfindo Yagambi were clearly separated from other samples, however, the seeds from commercial and non-commercial seeds (IOPRI B SMB and oil palm PT Harapan Sawita (OPHS) respectively were observed in one group. This study indicated that there are distinct groups of polyisoprenoid carbon chains randomly derived from cluster analysis in the origin of oil palm seeds.
