Agarwood Oil

ABSTRACT: Agarwood oil is a highly prized type of oil due to its unique aroma. The oil is extracted from the fragrant resin found in the agarwood tree (trunk).  The unique aroma and quality of agarwood resin and oil are contributed by the presence of certain chemical compounds. In this work, analysis and comparison of the chemical compounds of agarwood oil from A. malaccensis, A. sub-integra and a mixture of both were conducted.  The essential oils were diluted in hexane (5%) prior to gas chromatography mass spectrometry (GCMS) analysis performed using Agilent GCMS 7890A coupled with MSD quadrupole detector 5975 C.  Separation of analytes by gas chromatography was carried out using a Hewlett Packard HP-5MS silica capillary column (30 m X 0.25 mm X 0.25 mm). A total of 107 compounds were identified from the three samples of agarwood oils. Fifty-five (55) components were identified in A. malaccensis sample which contributes to the largest portion of the total compounds. About 20% of the compounds identified were aromatic and sesquiterpenes which have been revealed to be the main active compounds of agarwood oils which also give the aroma and pleasant odour of agarwood. Different compositions or profile of chemical components were found in agarwood oils from the two different species. Two compounds were commonly identified in all three samples namely 3-phenyl-2-butanone and alpha-cubebene.  Further studies are needed to refine the results which later can be used to assist detection and authentication of agarwood as well as its scientific-based grading. ABSTRAK: Minyak gaharu merupakan sejenis minyak beraroma unik yang mendapat permintaan tinggi dan mahal. Minyak ini diekstrak daripada resin beraroma yang terbentuk di dalam batang pokok gaharu. Keunikan aroma dan kualiti resin dan minyak gaharu ini bergantung kepada kehadiran bahan kimia tertentu. Penyelidikan ini menjurus kepada analisis dan perbandingan bahan-bahan kimia yang terdapat dalam minyak gaharu daripada spesis A. malaccensis, A. sub-integra dan campuran kedua-duanya. Minyak gaharu dilarutkan di dalam 5% heksana sebelum dianalisis menggunakan kromatografi gas Agilent GCMS 7890A berserta spektormetri jisim (MSD quadrupole detector 5975 C). Kolum kapilari silika Hewlet Packard HP-5MS (30 m X 0.25 mm X 0.25 mm) digunakan untuk pemisahan bahan-bahan kimia tersebut. Sejumlah 107 kompaun dikenalpasti dalam ketiga-tiga sampel minyak gaharu tersebut dengan 55 kompaun didapati di dalam sample A. malaccensis. Ini merupakan bahagian terbesar daripada keseluruhan kompaun. Sebanyak 20 % daripada keseluruhan kompaun yang dikenalpasti adalah daripada kumpulan seskuiterpena dan bersifat aromatik, juga merupakan kumpulan yang bertanggungjawab memberi aroma yang unik kepada minyak gaharu. Setiap spesis didapati mempunyai komposisi atau profil bahan kimia yang tersendiri. Dua kompaun iaitu 3-phenyl-2-butanone dan alpha-cubebene ditemui dalam ketiga-tiga sample yang dianalisis. Kajian lanjut adalah perlu untuk memurnikan dapatan hasil penyelidikan yang berpotensi bagi membantu pengenalpastian gaharu berserta pembangunan penggredan gaharu yang lebih saintifik.

Gas Chromatography-Mass Spectrometry (GC-MS) is normally used for direct analysis of chemical components existing in herbal medicines. The medicinal plants are having numerous bioactive components which are identified even at less than 1ng by using GC-MS or LC-MS analysis. The aim of this study is to identify the secondary metabolites present in the leaves of B. tomentosa using gas chromatography-mass spectrometry (GC-MS) analysis. In the present study the ethanol extract of the leaves of Bauhinia tomentosa has been subjected to GC-MS analysis, while the mass spectra of the compounds found in the extract was matched with the National Institute of Standards and Technology (NIST) library. GC-MS analysis revealed the presence of 14 secondary metabolites. These compounds were identified by comparing their retention times and peak areas with those from the literature and by interpretation of the mass spectra. The major secondary metabolites were DL-.alpha.-tocopherol (14.84%), 2-[(trimethylsilyl oxy]-, methyl ester, 1-alpha,2-alpha.-epoxy-1-beta-methylcholesta-4,6-dien-3-one (12.93%), pentacosenoic acid (12.71%), phytol (10.28%), Ethyl Isoallocholate (8.197%), Spirost-8-en-11-one-3-hydroxy-,(3-beta,5 alpha,14 beta,20 beta, 22 beta,25R)-(8.162%), Urs-12-en-28-ol (6.675%), 1-Octadecyne (5.702%) and Cholest-8-en-3-beta-ol,Acetate (5.426%). The compounds having area less that 5% were considered of no significance. These findings suggest that the presence of these secondary metabolites may be the cause for the properties exhibited by Bauhinia tomentosa. Thus, presence of various bioactive compounds justifies the use of the leaf for various ailments by traditional practitioners.

Purpose: To study the differences in lipid-soluble compounds from naturally-fermented Rhizoma Pinelliae fermentata (BXQ) samples, and fermentation products of BXQ using pure cultures of Bacillus subtilis, Aspergillus niger, and Meyerozyma guillermondii. Methods: First, unfermented BXQ (CTFJ-Q), traditional, naturally-fermented BXQ (CTFJ-H), and fermentation products of BXQ using pure cultures of Bacillus subtilis (XJFJ), Aspergillus niger (MJFJ), and Meyerozyma guillermondii (JMJFJ) were obtained. Their lipid-soluble components were then analyzed using gas chromatography-mass spectrometry (GC-MS) technology and principal component analysis (PCA). Results: GC-MS results showed that there were 26, 24, 27, 31 and 32 types of chemical components in CTFJ-Q, CTFJ-H, XJFJ, MJFJ and JMJFJ, respectively. Furthermore, PCA revealed that samples obtained using fermentation with pure cultures of the three microorganisms had unique chemical components. Conclusion: These results suggest that the microorganisms used for fermentation greatly influence the lipid-soluble components of BXQ. This finding is considered beneficial for the optimization of BXQ fermentation process.

This research aims to isolate oil from patchouli (Pogostemon cablin Benth) and identify the chemical components of patchouli oil using Gas Chromatography-Mass Spectrometry (GC-MS). Patchouli plant samples were obtained from Welulu Village, Kolaka Regency, Southeast Sulawesi Province. Fresh patchouli leaves are dried in the sun for four days to a constant weight. Patchouli leaves water content is 77.41% (w/w). Dry patchouli leaves are distilled using the water and steam method for two hours. Water and oil distillates are separated using a separating funnel. Patchouli oil obtained was dried using Na2SO4 anhydrous and yield 0.73% (w/w). The results of GC-MS analysis showed that patchouli oil contained 13 chemical components compounds, namely β-patchoulene (4.56%), cedr-8-ene (1.24%), trans-caryophyllene (7.96%), α-guaiene (18.61%), seychellene (5.70%), patchoulene (2.88%), eremophilene (1.33%), azulene (8.74%), delta-guaiene (18.90%), cyclohexanone (1.10%), globulol (1.88%), veridiflorol (4.39%), and alcohol patchouli (22.7%).
