“…Resin is a type of volatile chemical substance that permeates the heartwood of Agarwood trees [1]- [4]. This high resin formation resulting for a good quality of Agarwood oils [2], [5]- [7]. Agarwood oil is one of the most useful oils with a major use for everything from perfumery, medical industry, fragrances and also religious ceremonies [8]- [11].…”

The paper interprets data distribution by using boxplot pre-processing in classify the quality of Agarwood oil for eleven chemical substances into four different qualities. The varieties usage of Agarwood oil makes it considered as an expensive and valuable product on the essential oil market. Perfumes, fragrances, incense, aromatherapy, and traditional medicine are the most popular Agarwood oil applications. However, the classification of Agarwood oil grades does not yet have standard grading method. This because it has been graded manually into different qualities by using human sensory evaluation. Boxplot analysis involving eleven chemical subtances that will be focusing in this study by concerned the quality for low, medium low, medium high and high. ɤ-eudesmol, ar-curcumene, β-dihydro agarofuran, ϒ-cadinene, α-agarofuran, allo aromadendrene epoxide, valerianol, α-guaiene, 10-epi-ɤ-eudesmol, β-agarofuran, and dihydrocollumellarin compounds are the selected significant compounds that represent the input for boxplot. Agarwood oil consist 660 data samples from low, medium low, medium high, and high quality. The result in this study showed that the four selected significant compounds (ɤ-eudesmol, 10-epi-ɤ-eudesmol, β-agarofuran, and dihydrocollumellarin) are important as a marker for Agarwood oil quality classification. The identification of chemical substances on high quality done as reference for future research studies.

Agarwood (Aquilaria Malaccensis) oil stands out as one of the most valuable and highly sought-after oils with a hefty price tag due to its widespread use of fragrances, incense, perfumes, ceremonial practices, medicinal applications and as a symbol of luxury. However, nowadays the conventional method that rely on color alone has its limitations as it yields varying results depending on individual panelists' experiences. Hence, the quality identification system of Agarwood oil using its chemical compounds had been proposed in this study to enhance the precision of the Agarwood oil grades thus addressing the shortcomings of traditional methods. This study indicates that the primary chemical compounds of Agarwood oil encompass ɤ-Eudesmol, ar-curcumene, β-dihydroagarofuran, ϒ-cadinene, α-agarofuran, allo-aromadendrene epoxide, valerianol, α-guaiene, 10-epi-ɤ-eudesmol, β-agarofuran and dihydrocollumellarin. This study employed artificial neural network analysis with the implementation of Levenberg-Marquardt algorithm to identify the Agarwood oil grades. The study's findings revealed that this modeling system of five grades got 100% accuracies with mean square error of 0.14338×10-08. Notably, this lowest mean square error (MSE) value falls within the best hidden neuron 3. These study outcomes play a pivotal role in highlighting the Levenberg Marquardt- artificial neural network (LM-ANN) modeling that contribute to the successful of Agarwood oil quality identification using its chemical compounds.

“…Spreng, has been selected from the wild population and used as a scion for grafting cultivation. These excellent clones, namely "Qi-Nan", have the characteristics of more easily induced agarwood and high-quality agarwood [6][7][8][9]. For ordinary A. sinensis, it is almost impossible to obtain agarwood with more than 10% of the alcohol soluble extractive content only with the drilling method over one year, but this special agarwood germplasm of A. sinensis can have more than 40% of the alcohol soluble extractive content with the same inducing method [6].…”

In recent years, some new Qi-Nan clones of Aquilaria sinensis, which have the characteristics of easily induced and high-quality agarwood, have been selected and propagated by grafting seedlings. To date, research on the grafting of Qi-Nan seedlings is limited. In this study, the effects of grafting on physiological characteristics and endophytic fungi of seedlings within a short period after grafting were studied by means of histochemical observations, physiological index determinations and Illumina sequencing. The results showed that the grafting healing time of ordinary A. sinensis was at least 10 days shorter than that of Qi-Nan, according to the degree of lignification of callus, and the tissue basis for the healing was the interxylary phloem. The MDA content of Qi-Nan peaked earlier than that of ordinary A. sinensis. The contents of JA and ABA peaked earlier in ordinary A. sinensis, and the SA content was significantly higher than that of Qi-Nan at 20–40 days; on average, it was 17.33% higher than that of Qi-Nan. A total of 5 phyla, 28 classes, 84 orders, 197 families, 489 genera and 842 species of endophytic fungi were identified before and after grafting. After grafting, the abundance and diversity of endophytic fungi in ordinary A. sinensis and Qi-Nan decreased, and the endophytic fungi were significantly different before and after grafting. In ordinary A. sinensis, before grafting, Dothideomycetes was the dominant class, and after grafting, Sordariomycetes was the dominant class. The dominant class of Qi-Nan before and after grafting was Dothideomycetes. The dominant genus of ordinary A. sinensis before grafting was Devriesia, and after grafting, it was Fusarium; that of Qi-Nan before grafting was Hyweljonesia and after grafting was Arthopyrenia. Functional genes of the endophytic fungi were mostly related to carbohydrate metabolism and energy metabolism, which may be the reason why endophytic fungi promote agarwood formation in Aquilaria trees. The findings suggest that the healing of the grafting interface in A. sinensis seedlings was the result of multiple factors, and endophytic fungi of Qi-Nan scion changed after grafting.
