Abstract

Identification of wood species that are difficult to distinguish from their anatomical structure can be done through phytochemical (extractive substance) profiling. This research aimed to analyze the phytochemical profile as a sorter for three species of mangrove wood from Indramayu and Cilacap Regencies, Indonesia, using the liquid chromatography-mass spectrum. The phytochemical markers of taxonomic were the dominant compounds only found in one wood species. The results showed that the three types of wood are dominated by phytochemicals dissolved in ethanol. The results of LCMS analysis of the ethanol extract showed that the phytochemical markers were triterpenoid, flavonoid, and fatty acyls glycoside groups for Rhizophora apiculata, steroid and naphthalene groups for Bruguiera gymnorhiza, and alkaloid as well as fatty amide group for Bruguiera cylindrica. The dominant compounds that characterize these can be used in sorting between mangrove wood species. Keywords: characterizer, compound, mangrove, phytochemicals

Abstract

Agarwood leaves (Aquilaria malaccensis), a non-timber forest products, shows significant potential as a source of antidiabetic compounds. This study aims to evaluate the antidiabetic activity of agarwood leaves and their cytotoxicity on pancreatic beta-cells, as well as predict their compound bioactivity through an in silico approach. The leaves were extracted using ethanol, water, and a mixture of ethanol–water with the assistance of ultrasound irradiation. The extracts were then tested in vitro for their antidiabetic potential by assessing their ability to inhibit the alpha-glucosidase enzyme and their effect on insulin secretion, as well as their cytotoxicity on BRIN-BD11 pancreatic beta-cells. The phytocompounds in the extract were identified using liquid chromatography-mass spectrometry, and their binding behavior was studied by in silico molecular docking. Among the three, the ethanol–water extract showed the highest extraction yield. Cytotoxicity assays revealed that the ethanol–water extract was cytotoxic at high concentrations (1000 µg/mL), but safe at lower concentrations. The alpha-glucosidase inhibition was relatively weak. Nevertheless, the extracts significantly stimulated insulin secretion in BRIN-BD11 cells up to fivefold compared to untreated cells. In silico studies indicated that xanthone glycoside, flavonoid glycoside, and coumarin compounds exhibit strong binding affinities to multiple insulin-secretion-related proteins. These findings suggest that agarwood leaf extract, particularly ethanol–water extract, possesses promising antidiabetic activity through an insulinotropic mechanism. Keywords: agarwood, alpha-glucosidase, insulinotropic, molecular docking

Abstract

Penelitian ini bertujuan untuk menganalisis dimensi serat dan nilai turunan serat kayu gmelina (Gmelina arborea Roxb.) dan waru (Hibiscus tiliaceus L.) serta membandingkan karakteristik anatomi serat kedua jenis kayu tersebut. Sampel kayu dimaserasi menggunakan metode Schultze dan diamati secara mikroskopis pada pembesaran 40× dan 100×. Parameter yang diukur meliputi panjang serat, diameter serat, diameter lumen, dan tebal dinding sel. Data dimensi serat digunakan untuk menghitung nilai turunan serat berupa Runkel ratio, flexibility ratio, felting power, Muhlsteph ratio, dan coefficient of rigidity. Hasil penelitian menunjukkan bahwa kayu gmelina memiliki panjang serat 1251,65 µm, diameter serat 31,10 µm, diameter lumen 18,26 µm, dan tebal dinding sel 6,42 µm, sedangkan kayu waru memiliki panjang serat 1083,96 µm, diameter serat 22,69 µm, diameter lumen 15,72 µm, dan tebal dinding sel 3,48 µm. Nilai turunan serat kayu gmelina berturut-turut adalah Runkel ratio 0,70, flexibility ratio 0,59, felting power 40,24, Muhlsteph ratio 31,10, dan coefficient of rigidity 0,21, sedangkan kayu waru memiliki nilai Runkel ratio 0,44, flexibility ratio 0,69, felting power 47,77, Muhlsteph ratio 51,97, dan coefficient of rigidity 0,15. Berdasarkan total nilai turunan dimensi serat, kayu waru memperoleh skor 250 dan termasuk kelas kualitas II, sedangkan kayu gmelina memperoleh skor 200 dan termasuk kelas kualitas III. Hasil penelitian menunjukkan bahwa kayu waru memiliki serat yang lebih fleksibel dengan lumen relatif lebih besar dan dinding sel lebih tipis, sedangkan kayu gmelina memiliki serat yang lebih besar namun lebih kaku akibat dinding sel yang lebih tebal.
