Abstract

Curcuma zedoaria Rosc (Zingiberaceae), known as white turmeric or temu putih, is commonly used as traditional medicine in Indonesia. The toxicity of this herb needs to be studied to improve its application. This study aimed to evaluate the toxicity of the crude ethanol extract of temu putih rhizome against brine shrimp (Artemia salina) larvae and zebrafish (Danio rerio) embryos and to analyze the potential active compounds contained in the extract. The crude ethanol extract showed a 50% lethal concentration value (LC50) at 588 ppm against brine shrimp larvae and 224 ppm against zebrafish embryos. Based on the gas chromatography-mass spectrometry analysis, the suspected active compounds that play a role in the toxicity were epicurzerenone, curzerene, and curzerenone, while 2,4,6-trimethylacetophenone was the predominant compound.

Abstract

Antioxidants can prevent reactive oxygen-associated diseases, which trigger carcinogenesis, cardiovascular disease, and premature aging. India and Africa have mostly practiced sausage trees (Kigelia africana) as traditional medicine, whereas Indonesia is still limited. The research aims to determine the phytochemistry and bioactivity of the n-hexane fractions from crude methanol extract of the leaves and bark of the sausage tree as antioxidants and their toxicity. The sausage tree is derived from Waterpark Platinum Riau. The sausage trees were macerated with methanol and fractionated by n-hexane and ethyl acetate. All samples were tested for their antioxidant to 1,1-diphenyl-2-picrylhydrazyl (DPPH) and cytotoxicity to Artemia salina Leach larvae. Phytochemical results of methanol crude extract, n-hexane, and ethyl acetate fractions of leaves and sausage bark showed the presence of all secondary metabolites except alkaloids in the n-hexane fraction. Antioxidant and cytotoxic activity of stem and leaf bark ethyl acetate fraction was stronger than crude methanol extract and n-hexane fraction. Based on LC-MS/MS data, the secondary metabolite components that have contributed strongly antioxidant activity of this study are flavonoid compounds such as kaempferol and the derivatives, lignans (cubebin), and steroids (pregnant).

Abstract

Diabetes mellitus (DM) is a chronic metabolic disease distinguished by disrupted glucose metabolism, causing elevated blood sugar levels. One of the latest therapeutic strategies involves inhibiting dipeptidyl peptidase-4 (DPP-4) to regulate glucose metabolism. Emodin, a bioactive compound, has shown potential as a DPP-4 inhibitor, but its efficacy requires further research. This study aims to identify and assess emodin and its derivatives as potential DPP-4 inhibitors through a comprehensive in silico and in vitro analysis. Molecular docking analysis revealed that 3-ρ-toluoyl emodin (ρTE) had the lowest binding energy (-111.4 kcal/mol) among the tested compounds. Furthermore, in vitro testing showed consistent results in silico, indicating that ρTE had significant inhibitory activity with an IC50 value of 1.37 μM. Pharmacokinetic and physicochemical evaluations confirmed ρTE’s potential as a safe antidiabetic drug candidate. The research findings indicate that ρTE holds potential as a promising drug candidate for further development.

Abstract

Temulawak (Curcuma xanthorrhiza) dan temuputih (Curcuma zedoaria) termasuk tanaman herbal yang mempunyai potensi sebagai antitumor dan antikanker. Beberapa obat antikanker dan ekstrak herbal telah dilaporkan memiliki toksisitas yang tinggi dan menyebabkan malformasi pada embrio ikan zebra (Danio rerio). Penelitian ini bertujuan membandingkan toksisitas ekstrak etanol C. xanthorrhiza, C. zedoaria, dan campurannya (rasio 1:6) terhadap embrio ikan zebra. Rimpang C. xanthorrhiza dan C. zedoaria diekstrak dengan cara maserasi dalam etanol 80%. Ekstrak diuji toksisitas akut dengan embrio ikan zebra menggunakan metode OECD Guidelines for the Testing of Chemicals No. 236 (2013). Nilai lethal concentration 50 (LC50) campuran ekstrak adalah 82.9 ppm, berada di antara nilai LC50 masing-masing ekstrak (16.9 untuk C. xanthorrhiza dan 112.1 untuk C. zedoaria). Tingkat menetas embrio rendah pada ekstrak C. xanthorrhiza tetapi tinggi pada ekstrak C. zedoaria dan ekstrak campuran. Kelainan notokorda dan edema kantong kuning telur tinggi pada ekstrak C. xanthorrhiza tetapi rendah pada ekstrak C. zedoaria dan ekstrak campuran. Kelainan sirkulasi darah rendah pada ekstrak C. zedoaria tetapi tinggi pada ekstrak campuran. Edema perikardium dan koagulasi darah merupakan malformasi mayor pada semua ekstrak. Dapat disimpulkan bahwa campuran ekstrak etanol temulawak dan temuputih menyebabkan malformasi edema perikardium, koagulasi darah, dan secara sinergis menghambat sirkulasi darah, yang berkaitan dengan potensi antikanker. Selain itu, ekstrak campuran dapat menurunkan hambatan menetas, malformasi notokorda, dan edema kantong kuning telur.

Abstract

Coptotermes curvignathus is a termite pest that attacks buildings, plantations, and forests. Controlling this pest requires environmentally friendly natural materials. The bintaro plant (Cerbera odollam) are known in Indonesia as natural insecticides and traditional medicines because of their strong toxic properties, so they have the potential to be used in termite control. This study evaluated the efficacy of C. odollam leaf and fruit peel extracts as natural termiticides and their effectiveness against subterranean termite C. curvignathus. The extraction process used three solvents with different polarities: n-hexane, acetone, and ethanol. Anti-termite bioactivity tests were conducted following the Japanese Industrial Standard (JIS) 1571-2010 method. Ethanol extract from C. odollam leaves produced the highest yield (9.52%). Phytochemical analysis showed the presence of alkaloids, flavonoids, phenolics, steroids, and saponins in both leaf and fruit peel extracts. The anti-termite bioactivity test showed that the leaf extract with acetone solvent caused 97.33% mortality, while the fruit peel extract with ethanol solvent caused 100% mortality at a 5% concentration. This study demonstrates that C. odollam leaf and fruit peel extracts have strong potential as natural termiticides.

Abstract

Eleutherine bulbosa is known to contain diverse secondary metabolites with pharmacological potential. This study aimed to identify the bioactive compounds in the ethanol, n-hexane, and unsaponified n-hexane fractions of E. bulbosa bulbs and evaluate their antioxidant and antibacterial activities. The bulbs were extracted using ethanol, followed by n-hexane fractionation and saponification. Antioxidant activity was determined using the DPPH assay, and antibacterial activity was assessed against Staphylococcus aureus and Escherichia coli using the disc diffusion method. LC-MS/MS and GC-MS analyses identified compounds such as eleutherol, resveratrol, coniferaldehyde, and stigmasterol. The ethanol fraction exhibited the highest antioxidant activity (IC₅₀ = 47.54 ± 0.03 mg/L), while the unsaponified n-hexane fraction showed the strongest antibacterial effect (inhibition zone = 16.12 ± 0.16 mm). These findings confirm the potential of E. bulbosaas a natural source of antioxidant and antibacterial agents.
