“…Then, the 2 nd batch obtained sesquiterpenes of Humulane-1,6-dien-3-ol, Aristolene and 1,9-Dihydropyrene which are not identified in the 1 st batch and 3 rd batch. Besides that, this also can be proved in the previous study which is several different types of sesquiterpenes were found in agarwood of Aquilaria Sinensis species [11]. The soaking activity for pre-treatment also shows the effect towards the quality of agarwood oil.…”

Agarwood or its specific named, Aquilaria spp. is a precious tree in the world. It has been used widely in pharmaceutical industry, production of perfumes and incense raw material. In this study, the agarwood essential oil, species of Aquilaria maleccensis is being extracted by using hydrodistillation method. This study aims to analyse the present of chemical compound named sesquiterpenes in the agarwood essential oil. The effect of pre-treatment using soaking process on the agarwood within 7 days, 14 days and 21 days before proceed for hydrodistillation process had been done. The hydrodistillation process took 3 days before the sample of essential oil is collected. The sample is being analysed by using gas chromatography mass spectrometry (GC-MS). The result showed the existence of sesquiterpenes had been identified from all sample of three batches. However, different types of sesquiterpenes were identified for different batch. The highest sesquiterpenes content for 1 st batch is α-gurjunene with 2.95%, the 2 nd batch is ç-Himachalene with 0.292% and the 3 rd batch is same with the 1 st batch which is α-gurjunene with 0.356%. Keywords: agarwood, Aquilaria maleccensis, Sesquiterpenes, hydrodistillation, gas chromatography mass spectrometry Abstrak Gaharu atau nama spesifiknya, Aquilaria spp. adalah pokok yang sangat berharga di dunia. Ia banyak digunakan di dalam industri farmaseutikal, penghasilan minyak wangi dan bahan asas kemenyan. Dalam kajian ini, pati minyak gaharu, jenis Aquilaria maleccensis di ekstrak melalui kaedah penyulingan air. Tujuan kajian ini adalah untuk menganalisis kehadiran komponen kimia yang dinamakan sebagai sesquiterpenes di dalam pati minyak gaharu. Kesan pra rawatan menggunakan proses rendaman ke atas gaharu dilakukan antara 7 hari, 14 hari dan 21 hari sebelum dilanjutkan ke proses penyulingan air. Proses penyulingan air mengambil masa 3 hari sebelum sampel pati minyak gaharu diambil. Sampel tersebut tersebut seterusnya dianalisis menggunakan kromatografi gas spektrometri jisim (GC-MS). Keputusan menunjukkan kehadiran sesquiterpenes daripada ketiga-tiga kumpulan. Walau bagaimanapun, jenis sesquiterpenes berbeza dikenalpasti bagi setiap kumpulan. Kuantiti sesquiterpenes paling tinggi dalam kumpulan pertama ialah α-gurjunene iaitu 2.95%, kumpulan kedua ialah ç-Himachalene iaitu sebanyak 0.292% dan kumpulan ketiga adalah bersamaan dengan kumpulan pertama iaitu 0.356%.

“…The majority of the reported studies focused on A. sinensis. Sesquiterpenoids and 2-(2-phenylethyl)chromone derivatives (tested at 50 µg/mL) inhibited 12.3 to 61.9 % of acetylcholinesterase activity compared with tacrine (positive control), which inhibited approximately 70 % of the activity at 0.08 µg/mL (Li et al, 2015b;Yang et al, 2014a;Yang et al, 2014b). Neopetasane (1), an eremophilane sesquiterpene, showed the strongest inhibition (61.9 %) (Yang et al, 2014a).…”

“…The sesquiterpenoid 12,15-dioxo-α-selinene (121) showed the largest inhibition zone(20.02 ± 0.12 mm) for S. aureus, and (5S, 7S, 9S, 10S)-(+)-9-hydroxy-selina-3,11-dien-12-al (122) showed the largest inhibition zone (18.02 ± 0.07 mm) for R. solanacearum (Li et al, 2015b). Both compounds were tested at 10 mg/mL.…”

The resinous portion of the Aquilaria tree is called agarwood, a valuable non-timber product being used as medicine and incenses in Asia, Middle East, and Europe. Driven by high demand, the wild resources of agarwood-producing trees have been greatly threatened. This fragrant product contains many aromatic substances and is obtained from the pathological conditions of the wood of living trees. The knowledge regarding the technology for inducing agarwood and its continuous formation in the tree is still limited. To conserve the wild Aquilaria spp. and to supply sustainable amount of agarwood, cultivation of Aquilaria trees in combination with induction through artifi cial technique is seen as the best approach. In this chapter we will discuss the fundamentals of agarwood formation in the producing trees, the molecular pathway in its synthesis, current methods applied for agarwood induction in cultivated trees, and fi nally the factors infl uencing agarwood yield and quality.
