Cinnamomum Schaeffer is an aromatic, and woody plant species. This genus was famous because of “Cinnamon”, with distinguished economic significance as herbs and medicinal plant. There are few studies and limited information on Cinnamomum in Sabah, especially in phytochemical and taxonomical study, which indicate only little we know about this genus. Thus, the main justification for this study is to increase our understanding on this plant group. As well to updates and support a continuous efforts on phytochemical and taxonomical documentation of Cinnamomum spp. With objectives, To extract crudes and interpret phytochemical profiles. To extract essential oil and identify the volatile chemical constituents of selected Cinnamomum in Sabah. and to study and provide “Species Identification Key” for Cinnamomum spp. (Lauraceae) in Sabah. The methods used in this study comprise, chemotaxonomy assessment, Lab work, HPTLC, H-NMR and GC-MS. Not only that literature reviews and herbarium studies, fields sampling, taxonomical appraisal. As Result, Cinnamomum profiles for sample S.1, S.2, S.3, and S.4 perceived significant consistency and similarities in chromatographic bands of HPTLC results visualized under UV 366 nm, White RT and Molybdo derivatives and equivalent spectrum peaks developed between 7.0δ-8.0δ dan 3.0δ-5.0δ, which possibly represents aromatic, amides, esters, phenol and alkanes compounds based on Proton NMR Chemical Shift comparison for four C. burmanni samples collected from Sabah. The essential oil analysis via GC-MS have revealed 16 compounds above 3% for C. iners , with a major compounds alpha-Cadinene with 20.52%, follow by 10- epi-cis-Dracunculifoliol 15.98%, Sesquisabinene at 14.90%, Lavandulol 11.20%, whereas 16 compounds above 3% also for C. burmanni samples, and major identified compounds were Cinnamyl formate with 91.48%, follow by Hex-1-en-3-yl acetate 41.95%, and Selina-4(15),7(11)-diene for 10.70 %, Myrcenol 9.85% Nopol 9.33%. Not only that, 20 species of Cinnamomum were recognized in Sabah includes three possible new recorded species. Apart from that map distribution and identification key were provided for the use and future reference of Cinnamomum species in Sabah.
