With about 120 species, Aglaia is one of the largest genera of the plant family Meliaceae (the mahogany plants). Various Aglaia species have been investigated since the 1960s for their phytochemical constituents and biological properties. This research objective was to find secondary metabolites that have activity as anti-breast cancer compounds from endemic Indonesian Aglaia, such as Aglaia angustifolia Miq. Two cholestan type steroids, stigmast-5en-3α-acetat (1), as a new steroid with α-sterochemistry of acetyl moiety at C-3 and 23a-homostigmast-5en-3β-ol (2), with unusual side chain were isolated for the first time from the stem bark of Aglaia angustifolia Miq or known as segara tree in Kalimantan. The chemical structures of two steroids were identified with spectroscopic data, including IR, NMR (1H, 13C, DEPT 135°, HMQC, HMBC, NOESY, 1H-1H COSY) and HRTOF-MS, as well as by comparing with previously reported spectral data. These two steroids were isolated for the first time from this genus. Steroids 1 and 2 were evaluated for cytotoxic activity against MCF-7 breast cancer cells and showed weak activity with IC50 values of 829.0 and 903.0 µg/mL, respectively.

ABSTRACT. Triterpenoid is a group of natural products with various remarkable activities, including cytotoxic. One of the sources for this type of compounds is Swietenia genus belong to Meliaceae family. This genus known to contains various secondary metabolites including limonoids, flavonoids, and triterpenoids. Especially for triterpenoid, there is limited report on isolation as well as biological activity from Swietenia genus, such as Swietenia mahagoni. In this research, three triterpenoid compounds have been successively isolated and identified from n-hexane extract, namely, (-)-leucophyllone (1), toonaciliatavarin E (2), and moronic acid (3). All isolated were assed against MCF-7 breast cancer and CV-1 normal kidney cell lines. The result showed that only moronic acid (3) performed moderate activity against two cells with IC50 of 63.10 and 48.04 µM, respectively. The other isolated compounds (1 and 2) showed weak cytotoxicity with IC50 > 500 µM. Based on preliminary structure activity relationship, revealed that pentacyclic triterpenoid (moronic acid, 3) showed stronger cytotoxicity compare with tetracyclic triterpenoids (-)-leucophyllone (1) and toonaciliatavarin E (2).

This study aims to determine physicochemical properties, and caffeine analysis of green bean coffee essential oil (GBCEO) and roasted bean coffee essential oil (RBCEO) by maceration and soxhlet extraction methods. The results indicated that RBCEO by maceration method have higher percentage of yield compared to GBCEO. By the same to soxhlet extraction method, RBCEO also showed higher percentage of yield compared to GBCEO. The refractive index of the GBCEOm and GBCEOs have a lower acid value compared to RBCEOm and RBCEOs. The specific gravity obtained for GBCEOm, RBCEOm, GBCEOs, and RBCEOs ranged from 0.87 to 0.97. The results showed that GBCEOm has the highest saponification value followed by RBCEOs. GBCEOm has the highest iodine value followed by RBCEOs, while RBCEOm and GBCEOs have a similar iodine value. The peroxide value showed that GBCEOs, and RBCEOs by soxhlet extraction method have higher peroxide value. The GC-MS analysis revealed that GBCEOm has higher caffeine followed by GBCEOs with the percentages area of 9.31% and 7.36% respectively. Meanwhile RBCEOm has lower caffeine followed by RBCEOs with the percentages area of 7.36% and 4.28% respectively. This finding showed that GBCEO shows higher caffeine compound compared with RBCEO.

Three sesquiterpenoids, guaianediol (1), alismol (2), and spathulenol (3), were isolated from the n-hexane and ethyl acetate extracts of the stem bark of Dysoxylum amooroides. The three compounds were found in D. amooroides species for the first time. The structures of the isolated compounds were identified and established based on an extensive spectroscopic analysis involving HR-TOF-ESI-MS, IR, and NMR data, as well as a comparison with the previously reported works of literature. Compounds 1-3 were further assessed for cytotoxic effects against MCF-7 breast cancer cells. Guaianediol (1) showed inactive activity with IC50 > 100 µM, alismol (2) showed weak activity with IC50 value of 82.1 µM and spathulenol (3) showed considerable activity with an IC50 value of 15.2 µM. A brief structure-activity relationship and comparison with the previous works were also discussed to understand better the role of guaiane- and aromadendrane-type sesquiterpenoids in the biological activity perspective.

Antimicrobial resistance (AMR) poses an urgent global health concern, prompting the need for alternative therapeutic agents. This study evaluated the antimicrobial potential of ethyl acetate extracts from five medicinal plant species (Memecylon edule, Garcinia dioica, Syzygium sp., Memecylon caeruleum, and Aporosa octandra) collected from the geothermal Jaboi Crater in Aceh, Indonesia. Phytochemical profiling was performed using thin layer chromatography (TLC), and antimicrobial activity was assessed via TLC-bioautography against Escherichia coli, Staphylococcus aureus, and Candida albicans. The results revealed the presence of phenolic and terpenoid compounds, with antibacterial activity observed only against E. coli. No inhibition was detected against S. aureus or C. albicans. The study highlights the selective antimicrobial potential of geothermal plant extracts and underscores the relevance of bioautography as a rapid screening tool. While preliminary, these findings support further investigation into geothermal flora as a source of antibacterial compounds and call for advanced studies to isolate active constituents and explore their mechanisms of action.
