Abstract

Natural preservatives have been widely considered as non-synthetic materials that can prevent the biodegradation of wood due to subterranean termite attacks, namely Coptotermes curvignathus. Melia azedarach is a fast-growing species that has been widely studied for its antifeedant compounds and shows good potential to be developed as a biopesticide, especially as an anti-termite. This study aimed to identify the termicide and antifeedant properties of the wood, leaves, and bark extracts of Melia azedarach against subterranean termites and identify their bioactive compounds. The acetone extract from the three parts of the tree was fractionated. The most active fractions were selected from each part based on the percentage of termite mortality and antifeedant activity and analyzed for its bioactive compounds by pyrolysis GCMS. The ethyl acetate fraction of Melia azedarach bark exhibited strong toxic properties compared to other fractions. In the leaf section, the diethyl ether fraction showed the best termite repellent (antifeedant) properties. The anti-termite properties influenced phenolic compounds and organic acid that dominated the bark ethyl acetate fraction and leaf diethyl ether fraction. These findings show the great potential of bioactive compounds from biomaterials to be developed as a promising biopesticide. Keywords: anti-termite, bioactive compound, Melia azedarach, natural preservative

Abstract

Mango fruit (Mangifera indica L.) is the tropical fruit that grows easily in Indonesia with plenty varieties. This study aimed to determine the varieties of mango fruit and the most potent part of mango as antidiabetic agent through α-glucosidase inhibitory activities. Four types of mango fruit (indramayu, manalagi, harum manis, and budiraja) were used in this study. Each part of the mango fruit:peel, flesh, endosperm, and endocarp were extracted by maceration process with three different solvents (n-hexane, ethyl acetate (EtOAc), and ethanol (EtOH)). An ability of all 46 extracts in inhibiting the α-glucosidase at a concentration of 500 ppm were determined. Then 11 extracts with the high inhibition value were determined their IC50 (concentration to inhibit 50% activity) values. EtOAc extract of manalagi, indramayu, and budi raja endosperm had the lowest IC50 value which was not statistically significantly different (at 95%) with EtOAc extract of budi raja peel. The bioautographic Thin Layer Chromatogram showed that the most active band is characterized by white luminescence under UV 366 nm, yellow color under UV 254 and visible light. The band with Rf 0.93 from EtOAc endosperm extract of indramayu and manalagi and Rf 0.73 from EtOAc budi raja peel extract are the most active band which predicted as a flavonoid. The result adds the value of the peel and seed of mango, as well as an alternative in blood sugar control, which is easy to obtain, relatively cheap, and liked by the community.

Abstract

Acacia auriculiformis showed good potential to be developed as a raw material for bioactive compounds. The heartwood of A. auriculiformis is still rarely explored. The purpose of this study was to identify the bioactive components of the heartwood. Six compounds were identified from the heartwood through nuclear magnetic resonance and mass spectroscopy, namely the C-3,4',7,8 hydroxyl substituted flavonoids and chalcone. Two methylated teracacidins and chalcone-like teracacidin were identified for the first time in the A. auriculiformis heartwood, along with three known compounds. These compounds showed good radical scavenging and reduction activity, compared to crude extract and ascorbic acid, using three different antioxidant assays. The molecular structure-dependent activity was observed to affect the trend of the different antioxidant activities. This finding shows good potential for further development of plant parts of A. auriculiformis from Indonesia as new raw materials for medicines. Keywords: Acacia auriculiformis, antioxidant, chalcone, flavonoid, heartwood

Abstract

Bamboo is a potential material in the furniture, construction, and craft industries due to its rapid growth and good physical and mechanical properties. However, its vulnerability to attacks by wood–destroying organisms, particularly termites, necessitates preservation to extend its service life. This study evaluated the resistance of gombong bamboo to subterranean and drywood termites, as well as its color changes. The modification treatments involve boric acid equivalent (BAE) impregnation, heat treatment (60 °C, 150 °C, and 180 °C), and vegetable oils (linseed and neem oil). Statistical analysis using one-way ANOVA was performed to determine the significance of each treatment factor on weight loss and colour parameters, followed by Duncan’s Multiple Range Test for mean comparison. In addition, color change and the chemical composition of the most effective oil treatment in terms of termite resistance were analysed using Gas Chromatography-Mass Spectrometry (GC-MS). The results showed that BAE, neem oil, and the combined treatments (BAE-vegetable oils) effectively improved bamboo resistance to both termite tests. The synergy between BAE impregnation, heat treatment (180 °C), and neem oil produced the highest level of termite resistance. Heat treatment at elevated temperatures also caused significant colour changes, particularly a reduction in brightness (L*) and an increase in dark brown tones attributed to thermal degradation of hemicellulose and extractives. GC-MS analysis revealed that neem oil was dominated by fatty acids and other compounds known for their antimicrobial, antifeedant, and termite-repellent activities, which likely contributed to the enhanced biological performance of the treated bamboo. Keywords: bamboo modification, bio-based treatment, impregnation, sustainable bamboo utilization
