Physico-Chemical Properties of Cajeput Oil's from

Asteromyrtus brasii,is one of the cajuput oil tree species in Wasur National Park, Merauke, Papua. However, theinformation on the chemical compound and physical properties (qualities) of cajuput oil produced from this species is, stilllimited.Thisresearchaimedtomeasurethechemicalcompoundandphysicalpropertiesof cajuputoildistilledfromthe leaves of trees which grow at the Wasur National Park.Chemical compound analysis is using Gas Chromatography and Mass Spectrometer method (GC-MS method).The analysis on the physical properties was applied to the cajuput oil distilled using steam method. The distillation lasted for 4-5 hours, and every interval of 30 minutes the distilled cajuput oil collected cumulatively and the total collected oil was examined for the yield and phsyco-chemical properties.Thequalitiesof theoverallcajuputoilfrom treeleavescouldn'tsatisfythestandard(SNI06-39542006) because of the specivic gravity is below 0.9 and optical rotation of 9.8. Analysis result with GC-MS show there are 29 peak, with 5 of the them has the higher intensity identified as 1,8 cineole (34,88% concentration),Trans-.Beta.Ionon-5,6-Epoxide (21,26%), Formamide (CAS) Methanamide (11,20%), Acetic acid (CAS) Ethylic acid (8,14%) andAlphapinene(4,39%).
