Abstract

Persicaria odorata (Synonym of Polygonatum odoratum and Polygonum minus) leaves, locally known as Kesum leaves, is one of Indonesia's biodiversity species, particularly on Kalimantan Island, and it is contained a high concentration of essential oils. The extraction of essential oil from Kesum leaves commonly uses various methods, including solvent extraction, steam distillation, hydro-distillation, supercritical fluid extraction, microwave-assisted extraction, ultrasonic-assisted extraction, and so on, with various extract characteristics produced. Several studies reported that Kesum leaves essential oil has numerous advantages, including anti-bacterial, hepatoprotective, anti-tyrosinase, antioxidant properties, and so on. Future research will require additional and new techniques, particularly non-thermal extraction technology and other bioactivity tests, to improve yield and maintain the essential oil composition of Kesum leaves.

Abstract

A native herbaceous plant of Southeast Asia, lempuyang is also widely distributed in Indonesia. This plant's primary bioactive component, Zerombone, has a variety of bioactivities, including an anti-bacterial effect. Typically, transglycosylase and alanine racemase were necessary proteins for forming peptidoglycan membranes and are now frequently used as anti-bacterial targets. Thus, using an in-silico approach, this work assessed the interactions between the zerumbone and the protein targets. The PubChem database was searched for the zerumbone compound (CID 5470187). Transglycosylase (PDB code: 1SLY), alanine racemase (PDB code: 4WR3), and the control protein target were also obtained from the PDB database. The Molegro Virtual Docker 5.0 version and the Discovery Studio application 21.1.1 versions were used to interface with and visualize the protein target and zerumbone compound. The result demonstrated that, like the control, the zerumbone compound in lempuyang blocks the active sites of the transglycosylase and the alanine racemase. The zerumbone-alanine racemase complexes additionally showed lower energy binding than other complexes. In conclusion, zerumbone in lempuyang can be a new candidate for anti-bacterial agents by inhibiting the synthesis of membrane peptidoglycan via suppressing transglycosylase and alanine racemase activities.

Abstract

Bacterial infection and antibiotic resistance are popular issues nowadays. Several pre[1]vious reports performed antibacterial screening activities involving natural herbs and synthetic drugs. Alanine racemase and transglycosylase are essential proteins for peptidoglycan membrane synthesis in bacteria and an alternative target for antibacterial performance. This study identified six flavonoid compounds in Syzygium myrtifolium to perform the antibacterial activity. In silico study was conducted for modelling flavonoids – protein complexes. Five flavonoids from S. myrtifolium were taken out of he canonical smiles from the PubChem database and modelled three-dimensional structure using ChemDraw and molView. Targeted protein, alanine racemase and transglycosylase were downloaded from Protein Data Bank with ID 4WR3 and 1SLY. Ligands and proteins were interacted by Molegro virtual Docker 5.0 and visualized by Discovery studio version 21.1.1. Five flavonoids showed inhibition with alanine racemase and transglycosylase in the same active sites of control and sodium benzo[1]ate. According to the binding energy, calopiptin performed the lowest binding energy value in alanine racemase complexes, while 2-Propanone, 1,3-bis(5-nitro-2-furanyl) showed the lowest value of four other flavonoids at transglycosylase complexes. The type of interactions were electrostatic, hydrogen bonds, hydrophobic interactions and unfavorable ones. Low binding energy and varied interaction types indicated tight of ligand-protein interaction. In summary, five flavonoids inhibited alanine racemase and transglycosylase, and the peptidoglycane membrane synthesis in bacteria might be inferred.

Abstract

This study identifies the phytochemical compounds in ethanolic extracts of Syzygium myrtifolium leaves, applies it to developing composite bioplastics as a natural antibacterial agent, and compares it with composite bioplastics prepared with sodium benzoate, particularly regarding inhibition zone diameter and microstructure. The results showed that the phytochemicals were identified in the ethanolic extract of Syzygium myrtifolium leaves, like flavonoids, alkaloids, tannins, phenolics, terpenoids, and saponins. LC-MS confirming bioactive in it as auraptenol, calopiptin, quercetin-3-O-β-D-glucuronide, and quercetin-3-O-L-arabinopyranoside. Moreover, in vitro tests showed that composite bioplastics with the ethanolic extracts of Syzygium myrtifolium had inhibition zone diameter against E. coli, similar to those with sodium benzoate added. Additionally, the microstructure of the composite bioplastics with the ethanolic extracts of Syzygium myrtifolium was rougher, irregular, and more porous than those of another. It indicated that the ethanolic extract of Syzygium myrtifolium leaf could be used as a natural antibacterial agent to replace the chemical agent.

Abstract

Umbi uwi ungu (Dioscorea alata), dikenal sebagai keribang di Kalimantan Barat, memiliki potensi besar sebagai bahan baku bioplastik ramah lingkungan. Artikel ini bertujuan mengkaji potensi tepung umbi uwi ungu berdasarkan kandungan kimia, bioaktif, dan prospek aplikasinya. Tepung ini kaya akan pati dan polisakarida larut air yang penting untuk membentuk bioplastik. Selain itu, senyawa bioaktif seperti antosianin dan fenolik memberikan kapasitas antioksidan tinggi, meningkatkan stabilitas termal dan sifat fungsional lainnya. Kajian ini dilakukan dengan metode studi pustaka, menganalisis literatur dari tahun 2004 hingga 2024. Hasil penelitian menunjukkan bahwa tepung umbi uwi ungu memiliki potensi sebagai bahan baku bioplastik, namun diprediksi memiliki sifat mekanik kurang baik, seperti ketahanan terhadap air dan fleksibilitas. Untuk meningkatkan sifat mekaniknya perlu ditambahkan bahan lain, seperti plasticizer, polisakarida, atau zat aktif, baik zat aktif sintetis maupun alami. . Meskipun demikian, bahan ini berpotensi besar untuk mendukung keberlanjutan dengan mengurangi limbah plastik. Dengan penelitian lebih lanjut, tepung umbi uwi ungu dapat dikembangkan menjadi solusi inovatif untuk bahan kemasan ramah lingkungan di masa depan.
