Abstract:
Kandelia, a genus belonging to Rhizophoraceae has been reported to have two distinct species: K. candel and K. obovata. Mangrove plants are known to produce secondary metabolite mostly derived from isoprenoid (triterpenoid and phytosterol). Isoprenoid composition of leaves and roots of K. candel (L.) Druce and K. obovata Sheue, Liu & Yong were investigated and compared. Triterpenoid and phytosterol profile of both species was analyzed using Gas Chromatography with Flame Ionization Detector (GC-FID). Both species displayed difference composition either in the leaves or roots. In the leaves of K. candel, eight isoprenoids detected, with dominating of -amyrin, a member of triterpenoid. The ratio between triterpenoid and phytosterol was 73.2%:26.8%. By contrast, phytosterol dominated the isoprenoid proportional in the roots of K. candel (91.7%). Similar results were found in the K. obovata leaves and roots, a predominated phytosterol over triterpenoid, 59.6%, and 97.9%, respectively.
The present work suggested diversity composition of isoprenoid in both Kandelia.
