Abstract

Leucaena leucocephala (lmk.) de Wit) (leed tree) seeds have been fermented by Indonesian as a traditional food which is called tempeh. The fermentation products of legume seeds are good functional foods, since they contain many bioactive compounds. The objective of this study was to determine the bioactive compound contents of fermented lead tree seed, such as total phenolic, ascorbic acid, β-carotene and a-tocopherol. Antioxidant activity testing was carried out using the thiobarbituric acid reactive substances (TBARS) method. Analysis of total phenolics, ascorbic acid, β-carotene and a-tocopherol were carried out using the folin-ciocalteu method, iodine titration, spectrophotometry and iron (III) chloride-thiocyanate, respectively. Rhizopus oligosporus was used to ferment lead tree seeds for 0, 1, 2, 3 and 4 days. Fermented leed tree seed powder was extracted with petroleum ether followed by ethanol. In comparison to unfermented leed tree seed powder, the β-carotene and a-tocopherol of the fermented seed powder increased. The greatest enhancement of β-carotene and a-tocopherol contents were observed at day 2 of fermentation. The highest antioxidant activities of fermented leed tree seeds were also obained at day 2 of fermentation with 55.55±4.59 and 74.46±3.49% inhibition in petroleum ether and ethanol extracts, respectively. The results show that lead tree seed tempeh has high antioxidant activity due to the bioactive compounds contains, such as  phenolics, β-carotene and a-tocopherol. Therefore, leed tree seed tempeh could be used for possible commercial production of functional food to alleviate oxidative stress.

Abstract

Biosurfactant with efficient emulsification properties could be produced by Pseudomonas flourescens using cassava flour wastewater (manipueira) as media. The ability of P. flourescens to produce biosurfactant could suggest potential use in industrial and environmental applications. Media containing a mixture of natural manipueira and nutrient broth with 48 h fermentation was the optimum condition for the biosurfactant production. Based on UV-Vis and FT-IR spectra, the biosurfactant was indicated as rhamnolipids containing hydroxyl, ester, carboxylic and aliphatic carbon chain functional groups. Biosurfactant exhibited critical micelle concentration (CMC) value of 715 mg/L and reduced the surface tension of the water from 80 mN/m to 59 mN/m. The biosurfactant was able to decrease the interfacial tension about 51-70% when benzyl chloride, palm oil and kerosene were used as water-immiscible compounds. The biosurfactant was able to form stable emulsion until 30 days when paraffin, soybean oil, lubricant oil and kerosene were used as water-immiscible compounds.

Abstract

The synthesis of anethole-lauryl methacrylate (LMA) copolymer had been carried out by cationic polymerization using BF3O(C2H5)2 as the initiator without the use of solvent at room temperature (28-30 °C) over atmospheric N2 conditions. Polymerization was conducted by varying LMA concentration i.e. 2%, 4%, and 6%, (w/w) with respect to the anethole weight. Structural determination of co-poly(anethole-LMA) was done using FTIR and 1H-NMR spectrophotometer. The relative molecular weight (Mv) of co-poly (anethole-LMA) was measured by an Ostwald Viscometer at room temperature. Morphological characterization and surface area analysis of co-poly(anethole-LMA) was performed using SEM and SAA, respectively. The successful synthesis of co-poly(anethole-LMA) was proven by the disappearance of vinyl group absorption at 1696, 1638, 965, and 938 cm-1 of the FTIR spectra, as well as the loss of vinyl group proton signals at 6.4-5.5 ppm in the 1H-NMR spectra. Increasing the weight of the LMA affected the characteristics of co-poly(anethole-LMA). The relative molecular weight of co-poly(anethole-LMA) was found to rise by increasing the weight of LMA. The Mv of co-poly(anethole-LMA) 2%, 4%, and 6% were 32378.62, 50611.05, and 65133.79 g/mol, respectively. The morphology of co-poly(anethole-LMA) showed that the surface distance between particles was getting tighter and the highest surface area in co-poly(Anethole-LMA) 6% was 233.80 m2/g.

Abstract

The synthesis and characterization of a novel Cu(II)-3-picolylamine complex were successfully carried out, aiming to explore the structural properties and antibacterial potential. The complex was synthesized by reacting CuSO4.5H2O with 3-picolylamine in a 1:4 molar ratio, yielding a dark blue precipitate (78.14% yield). Characterization techniques, including UV-Vis spectroscopy, FTIR, thermal analysis (TG/DTA), magnetic susceptibility, and powder XRD, confirmed the formation of the complex with the proposed formula [Cu(3-picolylamine)4]SO4.5H2O. The complex exhibited a square planar geometry around the Cu(II) ion, coordinated through nitrogen donor atoms of the ligand, with the sulphate ion acting as a counter ion. Thermal analysis revealed a two-stage decomposition process, with the release of five water molecules at 55–130°C and ligand decomposition at higher temperatures. Magnetic susceptibility measurements indicated paramagnetic behaviour with an effective magnetic moment of 1.86 BM, consistent with a d9 configuration. Despite its well-defined structure, the complex showed no antibacterial activity against Staphylococcus epidermidis ATCC 12228 and Pseudomonas aeruginosa ATCC 27853 at all concentrations up to 1000 ppm. The lack of activity was attributed to reduced lipophilicity and the presence of hydrophilic counterions, hindering bacterial cell wall penetration.

Abstract

Cendana (Santalum album L.) mengandung berbagai senyawa volatil, tumbuh di beberapa wilayah di Gunungkidul, Yogyakarta. Penelitian ini bertujuan untuk: (1) mendeskripsikan profil kimia senyawa volatil Santalum album L. dari Nglanggeran, Wanagama, dan Petir; (2) membandingkan senyawa volatil cendana di ketiga lokasi tersebut; dan (3) merekomendasikan praktik silvikultur untuk Santalum album L. di masing-masing lokasi berdasarkan profil kimia volatilnya. Minyak atsiri diekstraksi dari sampel kayu tiga pohon yang dipilih secara acak di setiap lokasi menggunakan n-heksana dan dianalisis dengan GC-MS menggunakan kolom HP-5MS UI (30 m × 0,25 mm × 0,25 µm) dengan program suhu oven dari 50 °C hingga 280 °C selama 53 menit. Dari sembilan kromatogram ditemukan empat belas senyawa volatil valid, termasuk hidrokarbon alifatik (undekana, pentadekana, isomer trimetil dodekana) dan alkohol seskuiterpena (α-santalol, β-santalol). Profil kimia bervariasi antar lokasi tumbuh yang berbeda: sampel dari Petir menunjukkan kadar α-santalol tertinggi (9,25%) dan β-santalol (11,38%), yang memenuhi standar kualitas internasional, sementara Nglanggeran dan Wanagama didominasi oleh alkana (5,76–8,45%). Temuan ini konsisten dengan pengamatan global mengenai pengaruh asal benih (provenance) terhadap komposisi minyak Santalum album. Statistik deskriptif (rata-rata, rentang, koefisien variasi) digunakan untuk perbandingan lokasi, memberikan alternatif praktis untuk skrining silvikultur tahap awal. Protokol yang sederhana dan hemat biaya ini memungkinkan praktisi mengidentifikasi lokasi optimal untuk produksi minyak bernilai tinggi. Penelitian ini merekomendasikan Petir sebagai lokasi unggulan untuk hasil minyak premium dan menyarankan penerapan perlakuan stres terkendali di lokasi lain guna meningkatkan sintesis santalol. Secara keseluruhan, penelitian ini menyediakan kerangka kerja praktis untuk mengintegrasikan profil kimia GC-MS dalam pengambilan keputusan silvikultur dan mendukung verifikasi forensik asal Santalum album L. di masa depan. Kata kunci: Cendana (Santalum album L.); Profiling GC-MS; Gunungkidul; implikasi silvikultur; senyawa volatil kayu.

Abstract

In vitro antibacterial activity of chalcone derivatives from “temu kunci” (K. pandurta) rhizomes against clinical isolate bacteria has been done. Two chalcone derivatives, panduratin A (1) and 4-hydroxypanduratin A (2) were isolated from Kaempferia pandurata rhizomes. Isolation of the chemical components were done with extraction (maceration), vacuum liquid chromatography and radial chromatography methods. The structures were determined by NMR spectroscopy (1H-NMR, 13C-NMR, 1D and 2D), then compare with data from literatures. Antibacterial activity was carried out with reference to the CLSI microdilution method, against eight clinical isolate bacteria such as Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Enterobacter aerogenes, Pseudomonas aeruginosa, Salmonella typhi, Shigella dysentriae and Vibrio cholerae. Compounds 1 and 2 showed significant antibacterial activity with highest activity against S. aureus and B. subtilis with MIC values of 2.4 to 18.8 µg/mL and MBC values of 4.8 to 37.5 µg/mL. These results showed these compounds as potential antibacterial agent for clinical isolate bacteria.

Abstract

Enhancing Essential Oils Yield through Initial Maceration using Ultrasonication Method at Rumah Atsiri Indonesia. Metode ekstraksi minyak atsiri yang paling umum digunakan adalah destilasi uap. Pada umumnya, metode destilasi uap banyak digunakan oleh industri kecil termasuk di Rumah Atsiri Indonesia (RAI), karena memiliki beberapa keuntungan, diantaranya pengoperasian yang mudah serta peralatan yang sederhana. Akan tetapi, metode ini juga memiliki beberapa kelemahan, seperti membutuhkan waktu yang cukup lama dan hasil produksi yang kurang optimal. Untuk mengatasi kelemahan tersebut, solusi yang dapat dilakukan adalah melakukan proses destilasi minyak atsiri yang didahului maserasi dengan bantuan ultrasonik. Bekerja sama dengan RAI, Tim Riset Group Natural Products and Synthetic Organic Chemistry Prodi Kimia FMIPA UNS telah melaksanakan Program Pengabdian kepada Masyarakat (PkM). PkM bertujuan memberikan penyuluhan sekaligus praktik mengenai cara destilasi minyak atsiri dengan memulai proses maserasi dan menerapkan teknik ultrasonikasi di RAI. Pendekatan ini bertujuan untuk meningkatkan efisiensi dan hasil proses destilasi dengan menggunakan gelombang ultrasonik untuk membantu memecah bahan tanaman sebelum destilasi. Hal ini memudahkan untuk mengekstrak lebih banyak minyak dan meningkatkan kualitas minyak atsiri secara keseluruhan. Kegiatan dimulai dengan diskusi tentang teori dan aplikasi maserasi awal dengan metode ultrasonikasi. Sesi selanjutnya adalah praktik maserasi awal dengan metode ultrasonikasi sebelum dilakukan destilasi. Luaran dari pelatihan ini adalah adanya peningkatan performa metode destilasi minyak atsiri. Hasil perlakuan ekstraksi awal dengan teknik ultrasonikasi bisa meningkatkan rendemen minyak sereh wangi dari 0,86% menjadi 1,86% atau meningkat 2,2 kali lebih banyak dibandingkan tanpa maserasi awal.
