Investigation
of Agarwood Compounds in Aquilaria malaccensis & Aquilaria Rostrata
Chipwood by Using Solid Phase Microextraction by Daoud Tajeldeinn Ahmaed in BJSTR
Abstract
The aim of this study was to characterize and profile the chemical constituents of Aquilaria malaccensis & Aquilaria rostrata
chip wood
by using solid phase micro extraction. In this study high grade of agar
wood chip wood was investigated. Two types of extraction performed
by SPME; were direct extraction of smoke which coating fiber adsorbs
analyte directly from sample matrix and headspace volatile of incense;
that adsorbs analyte indirectly from the matrix. By using 50/30 μm
divinylbenzene-carboxen-polydimethysiloxane (DVB-CAR-PDMS) fiber.
As a result at least 100 compounds were identified in incense smoke,
whereas in headspace volatile more than 70 compounds. The gas
chromatography (GC) was tagged on, to extract and analyze volatile
compounds. The average area percentages of these compounds were
calculated by using factor analysis of PCA. The major compounds
extracted from Aquilaria malaccensis chip wood by using headspace
volatile
of incense were kessane (29.229), α-guaiene (24.683) and
β-dihydroagarofuran (11.391), while β-selinene (0.976), caryophllene
oxide (0.968),
α-muurolene (0.887) and epoxy bulnesene (0.859) were major compound
obtained by using direct extraction of smoke.The main compounds extracted from Aquilaria rostrata chip wood
by using headspace volatile of incense were β-dihydroagarofuran (53),
khusiol (0.929) and ϒ-gurjunene (0.820) whereas by using direct
extraction of smoke were α-gurjunene (5.54), β -caryophllene (3.89), and
α-guaiene (2.7). Hence, this research proves that characterization of
agarwood by using headspace volatile of incense and direct extraction
of smoke can acts as indicator before further extraction and correlate
agarwood compound from incense smoke and volatile compound with
agarwood oil.
