  <abstract>Agarwood, a valuable resin from Aquilaria malaccensis, is threatened by overexploitation due  to high demand in the fragrance industry. This study aims to address sustainable production  challenges by investigating inoculation techniques to enhance agarwood formation. This study  aims to enhance agarwood production through inoculation techniques and analyze the resultant  chemical profiles of Agarwood (Aquilaria malaccensis). The primary objectives were to  inoculate agarwood trees using the Chemjet Technique, to analyze the chemical compounds of  agarwood chip wood using chromatography; and to compare the chemical profiles of  inoculated versus naturally occurring agarwood. A field study was conducted in a plantation in  Pahang, involving five Aquilaria malaccensis trees. One healthy tree served as a control, while  one wild tree acted as a standard reference. Three trees were inoculated using the Chemjet  method with Oudine formulation. After a 12-month inoculation period, resin accumulation was  observed and harvested. The resin and non-resinous wood were prepared for analysis using  Headspace Solid-Phase Microextraction (HS-SPME) followed by Gas Chromatography-Flame  Ionization Detection (GC-FID) and Gas Chromatography-Mass Spectrometry (GC-MS). The  findings revealed that inoculated trees exhibited uneven coloration with darker patches  localized in infected areas, indicating successful resin production. Chemical profiling  demonstrated significant variability in compound presence among individual trees. Wild  agarwood exhibited high levels of sesquiterpenes, with δ-Guaiene and α-Guaiene displaying  relative peak areas of 39.05% and 15.04%, respectively. In contrast, inoculated trees showed a  higher abundance of sesquiterpenoids, with Tree 1 exhibiting 10.03% Epi-α-Bisabolol, Tree 2  showing 7.87% Cyperotundone, and Tree 3 demonstrating 12.56% Rotundone. Notably,  terpenes such as δ-Guaiene and α-Caryophyllene were abundant across the trees suggest that  marker compound are present in high quality agarwood, whereas inoculated trees displayed a  broader range of compounds with lower peak intensities. Consistently, Caryophyllene oxide  emerged as a prevalent compound across all samples. This study suggests that inoculation  stimulates a more diverse chemical profile in agarwood, potentially as an adaptive response to  environmental stressors or pathogen attacks.</abstract>
