Study About Agarwood Oil (Aquilaria crassna Pierre) in Phu Quoc Island National Park, Vietnam | Chapter 01 | Research Aspects in Biological Science Vol. 1

 In order of decreasing degrees of resin buildup, the results of Agarwood quantity could be divided into three groups: high group 66, 59, 58; average group 20, 50, 13, 26; and low group 32, 15, 324 and 311. Branch 66 yielded the maximum quantity, 0.235 ml/kg in the laboratory and 0.895 ml/kg in industry.

The overall components of 20 years Agarwood oil were found to be 84 compounds, with the majority of sesquiterpenes such as -Eudesmol, -Eudesmol, -Tumerone, -Selinene, -Selinene and a substantial number of fat acids such as Tetradecanoic acid and Hexadecanoic acid.

Because they have a high number of sesquiterpen components and dark colour products, Branches 66 gathered in the dry season provide good Agarwood oil.

Many criteria must be considered while measuring the quality of Agarwood oil; however, in this experiment, two aspects were evaluated: colour of essential oils and chemical compositions. The colour was graded on a scale of 1 to 7, and the GC-MS method was used to identify the components in essential oils from four different species (3 high resins and 1 average resin). The overall composition of 20-year-old Agarwood oil was discovered to contain 84 compounds, mostly sesquiterpenes like -Eudesmol, -Eudesmol, -Tumerone, -Selinene, -Selinene, and a substantial number of fat acids like Tetradecanoic acid and Hexadecanoic acid. Additional, the study showed that no difference in results between two scales.

The genetic diversity results were compared to the genetic chloroplast genome diversity of the Aquilaria crassna plant groupings that produce aloe wood in different ways. We've discovered a link between the Aquilaria crassna plant groups' origins. Except for the tree with code M106, all of the other tree groupings have a common ancestor. However, they have differing resin-accumulation capabilities, indicating that genetic factors do not play a significant role in the production of aloe wood.

The 400bp DNA found in plant groups that accumulate a lot of resin is part of a gene called Matk. It exists in the chloroplast genome of plants, and this discovery aided in the development of a directive with promising possibilities for the hunt for plants capable of accumulating large amounts of resin.

Furthermore, we confirmed that the aldose reductase gene exists in Aquilaria crassna plants, and that it is involved in the production of aloe wood. However, the expression levels of genes in Aquilaria crassna plants differ. We also mentioned a symbiotic fungus on the Aquilaria crassna tree that boosts the potential to accumulate resin like aloe wood, as well as Penicillium and Aspergilus fungi. In addition, the fungus was discovered in the Thysanophora sp. and Eupenicillium sp. lines.
