Objective: This research aimed to determine the antioxidant activity of cream-containing Agarwood leaf extract using the DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical. Method: The sample was extracted by 70% ethanol and formulated at concentrations of 1% weight/volume (w/v), 3% w/v, and 5% w/v. Physical characteristics and antioxidant activity were evaluated. Results: The results showed that the agarwood leaf extract cream in all concentrations fulfilled all the requirements related to physical characteristics of good topical preparations, including organoleptic, homogeneity, pH, spreadability, and adhesion. The IC50 values of the agarwood leaf extract cream at the concentrations of 1% w/v, 3% w/v, and 5% w/v were 68.371, 62.602, and 57.756 ppm, respectively.

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.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Investigation of Agarwood Compounds in Aquilaria malaccensis \u0026 Aquilaria Rostrata Chipwood by Using Solid Phase Microextraction","attachmentId":54991143,"attachmentType":"pdf","work_url":"https://www.academia.edu/35129641/Investigation_of_Agarwood_Compounds_in_Aquilaria_malaccensis_and_Aquilaria_Rostrata_Chipwood_by_Using_Solid_Phase_Microextraction","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/35129641/Investigation_of_Agarwood_Compounds_in_Aquilaria_malaccensis_and_Aquilaria_Rostrata_Chipwood_by_Using_Solid_Phase_Microextraction"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="30041822" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/30041822/Comparison_of_phytochemicals_present_in_Aquilaria_malaccensis_Lam_Agarwood_and_Gyrinops_walla_Gaertn">Comparison of phytochemicals present in Aquilaria malaccensis Lam.

A. malaccensis produces resin called agarwood that has a high economic value in perfumery industry. G. walla also produces a resin similar to agarwood. Thus, screening of phytochemicals present in A. malaccensis and G. walla would be important. Stem samples of test species were collected and air dried. After that they were size reduced and phytochemicals were extracted using soxhlet extractor with two different solvents. Extracts were concentrated using rotary evaporator and concentrated samples were subjected to Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Obtained chromatograms were used to identify and compare the phytochemical constituents. Dichloromethane found to be better solvent than acetone to extract phytochemicals. Phytochemical composition of A. malaccensis and G. walla are not similar even though they share some phytochemicals in common. Major compounds that are responsible for the fragrance of agarwood are absent in both stem samples when collected in immature stages. This study could be extended to further optimize phytochemical extraction procedure, screening protocol and GC-MS programme.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Comparison of phytochemicals present in Aquilaria malaccensis Lam.

Antioxidants are compounds that can inhibit free radical reactions in the body. Free radicals have an impact on the pathogenesis of several diseases in humans due to oxidative stress in cells. The purpose of this study was to determine the class of secondary metabolites of agarwood bark and antioxidant activity and to compare the value of IC50 (Inhibitory concentrations) of the methanol extract of agarwood bark with the IC50 of vitamin C in the DPPH method using UV-Vis spectrophotometry. The methanol extract of agarwood bark was macerated using methanol, then determined the content of secondary metabolites of Simplicia. The determination of antioxidant activity was carried out on the methanol extract of agarwood bark with the addition of DPPH at various concentrations.
