Analysis of essential oil of eaglewood tree (Aquilaria agallocha Roxb.) by gas chromatography mass spectrometry BJP

Investigation of Agarwood Compounds in Aquilaria malaccensis & Aquilaria Rostrata Chipwood by Using Solid Phase Microextraction

“…Many of compounds detected in the main chromatograms of these sample were pyrolysis products especially in the smoke sample, while their present in the incense volatile are less and that can be resulted from the increased temperature which applied to burned sample, these products as toluene, furfural, o-xylem, benzaldehyde, phenol, p-methylanisol, salicylaldehyde, acetophenone, P-cresol, nonanal, naphthalene and vanillin; some of the sesquiterpenes are also can be pyrolyzed products from the resin. These finding also confirmed by Isihara (1993) and many of these pyrolyzed form are also reported by Pripdeevech (2011) in his study for the oil of agarwood [16,18,[29][30][31][32] The present of 2-butanone -4-phenyl are significant in the smoke sample only, while aromadendrene, elemol, dihydro β-agarofuran and ɤ-selinene are presented in the volatile sample more than smokes in both species of Aquilaria malaccensis & Aquilaria rostrata kessane has not reported before since the early studies on agarwood were carried out in the lower capacity of the used GCMS instrument today some of the investigation used 20 eV, and not, as usual, at 70 eV beside the uses of the more advance NIST library as search tool to identify the compounds [32][33][34].…”

Mathematical modeling for extraction of essential oil from Aquilaria crassna by hydrodistillation and quality of agarwood oil

“…The comminuted wood (3,000 g) was soaked in distilled water (27,000 g) for up to 7 d (Liu et al, 2008;Bhuiyan et al, 2009) in order to break down the parenchymatous and oil glands. This ratio of agarwood to distilled water (1:9) is usually applied in the industrial production of agarwood oil.…”

“…However, hexadecanoic acid or palmitic acid and 1,5-diphenyl-3-pentanone are not the fragrant agents. Agarospirol was the compound Table I Parameters of kinetic model at various temperatures Bhuiyan et al, 2009). Therefore, agarospirol should be a marker compound of the agarwood oil from A. crassna.…”

Endophytic actinomycetes isolated from Aquilaria crassna Pierre ex Lec and screening of plant growth promoters production

“…This plant harvested annually in Indonesia ranged from less than 30,000 to more than 100,000 plants felled (Soehartono and Newton 2001) and it has also been used in pharmaceutical industries. The oil obtained from this plant has been consumed as a stimulant, cardiac tonic and carminative (Bhuiyan et al 2009). The stem of this plant has been used in the treatment of cough, acroparalysis, courap, asthma and it also shown to inhibit the immediate hypersensitivity reaction by inhibition of histamine release from mast cells (Kim et al 1997).…”
