Gaharu（沉香）是一种芳香木材，通常来自沉香属（百里香科）的患病木材，通常在树上出现深色斑块或条纹。由于其强烈，独特的香味和药用特性，gaharu油是非常有价值的香料成分和香。Gaharu可以分为各种等级; A级，B级，C级和D级，它们通常根据物理特性，Gaharu形成及其独特的气味进行分级。较低的等级，如C级，通常被蒸馏以获得gaharu油。作为一个正在进行的研究的一部分，一些马来西亚gaharu油的化学分析和评价其潜在的有益特性; gaharu油从不同来源进行了分析和比较，通过GC和GC-MS。识别的化学成分是基于计算的保留指数和质谱数据与文献值的比较。对这些油的检查表明，在GC图谱、浓度和化学成分方面存在一些变化和差异。大部分的精油配置文件是复杂的，并由倍半萜类化合物及其氧化衍生物。然而，检测到常见的化合物，如3-苯基丁酮、α-愈创木烯、β-沉香呋喃、α-沉香呋喃、沉香螺醇和jinkoh-eremol。
Gaharu (agarwood) is a fragrant wood that is usually derived from the diseased timber of the genus Aquilaria (Thymelaeceae) and often occurs as dark coloured patches or streaks in the tree. Due to its strong, unique scent and medicinal properties, gaharu oil is greatly valued as perfumery ingredient and incense. Gaharu may be classified into various grades; Grade A, B, C and D and they are often graded according to the physical properties, gaharu formation and its unique scent. The lower grades such as Grade C are often distilled to obtain gaharu oils. As part of an on-going research on the chemical profiling of some Malaysian gaharu oils and evaluation of their potential beneficial properties; gaharu oils obtained from different sources were analysed and compared by GC and GC-MS. Identification of the chemical components was based on comparison of calculated retention indices and mass spectral data with literature values. Examination of the oils showed some variations and differences in terms of GC profiles, concentration and chemical components. Majority of the essential oil profiles were complex and made up of sesquiterpenoids and their oxygenated derivatives. However, common occurrences of chemical compounds such as 3-phenyl-butanone, α-guaiene, β-agarofuran, α-agarofuran, agarospirol and jinkoh-eremol were detected.
