Abstract

Centella asiatica and Curcuma domestica are recognized for their wound-healing properties. This study investigated the synergistic effects of combining these plant extracts with stingless bee (Heterotrigona itama) honey on wound healing in rabbits. Ethanolic extracts of C. asiatica and C. domestica were prepared in a 1 : 10 ratio. Blended formulations containing 20% plant extracts and 80% honey were created in two ratios: 1 : 1 and 2 : 1. The total flavonoid and tannin content of the plant extracts were quantified. Male rabbits were subjected to a wound-healing model, and the formulations were applied topically for seven days. Wound healing was assessed, and the results were compared to a positive control. The ethanolic extracts of C. asiatica and C. domestica were rich in flavonoids and tannins. The blended honey formulations exhibited promising wound-healing effects, with Formula 2 (2 : 1 ratio of plant extracts) demonstrating slightly superior results compared to Formula 1 and the positive control. These findings suggest the potential of the combined extracts of C. asiatica, C. domestica, and H. itama honey as effective wound-healing agents.

Abstract

Ethnobotany is an interdisciplinary field that explores the relationship between humans and plants, particularly in the context of traditional medicinal practices. In many rural and indigenous communities, traditional knowledge of medicinal plants remains essential for primary healthcare, especially where access to modern medical services is limited. Pinang Jatus Village, Paser District, East Kalimantan Province, is one such community where ethnobotanical practices continue to play a significant role in daily life. However, the specific plants used, methods of preparation, and ailments treated have not been systematically documented. This study aimed to identify the types of medicinal plants used by the residents of Pinang Jatus Village, the traditional methods of preparation, and the diseases commonly treated with these plants. A quantitative and descriptive research approach was applied, using purposive and snowball sampling techniques to select 30 informants. The study employed a qualitative framework through in-depth interviews, complemented by quantitative analyses using the Use Value (UV), Informant Consensus Factor (ICF), and Fidelity Level (FL) measures. Data were collected through semi-structured interviews. The study identified 24 plant species used for medicinal purposes, with the Asteraceae family being the most dominant. The most commonly utilized plant parts were leaves, followed by roots and seeds. The findings demonstrate that the community possesses rich ethnobotanical knowledge and continues to rely on a diverse range of plant species for traditional healing. These results not only fulfill the study’s objectives but also emphasize the importance of preserving traditional knowledge and highlight the potential for future pharmacological research based on these local practices.

Abstract

Peradangan adalah respons perlindungan sistem imun terhadap  kekebalan rangsangan berbahaya. Aterosklerosis, penyakit pembuluh darah progresif yang ditandai penumpukan plak lemak dinding arteri, disebabkan oleh peradangan. NLRP3 berperan dalam berbagai penyakit inflamasi, termasuk aterosklerosis. Alternatif berbasis bahan alami seperti propolis Homotrigona apicalis dapat mengurangi peradangan dan mencegah perkembangan penyakit. Sebaliknya, obat antiinflamasi seperti NSAID dan steroid sering memiliki efek samping. Untuk pemahaman dari interaksi ini, digunakan pendekatan molekuler docking. Pendekatan ini memungkinkan penggunaan senyawa propolis H.apicalis sebagai antiinflamasi yang aman dan efektif. Dengan menggunakan metode molekuler docking, penelitian ini mengkaji potensi senyawa propolis H. apicalis sebagai penghambat jalur peradangan NLRP3 pada aterosklerosis. Senyawa dalam propolis, seperti Alpha-Amyrin dan Beta-Amyrin, menunjukkan aktivitas anti-inflamasi melalui interaksi hidrofobik dengan residu kunci pada protein NLRP3. Nilai afinitas ikatan tinggi Alpha-Amyrin (-10,7) kcal/mol dan Beta-Amyrin (-10,6kcal/mol), menunjukkan potensi penghambatan inflamasi yang efektif. Maka dapat disimpulkan bahwa Senyawa Alpha-Amyrin dan Beta-Amyrin dari propolis H. apicalis memiliki potensi sebagai penghambatan jalur inflamasi NLRP3 dalam aterosklerosis. Hal ini mengindikasikan Alpha-Amyrin sebagai kandidat yang sangat kuat dengan Beta-Amyrin sebagai senyawa pendukung dengan potensi serupa.

Abstract

Propolis is a product produced by bees that has various benefits. As a natural substance that can be used for medicinal purposes, propolis needs to undergo acute toxicity testing to determine the safety of its use and to estimate the degree of damage that may occur. This study aims to compare the acute toxicity potential of propolis extracts from two species of stingless bees, Geniotrigona thoracica and Heterotrigona itama, based on LD50 and to assess toxic symptoms. The testing was conducted using the Organization for Economic Co-operation and Development (OECD) No. 425 method: Acute Oral Toxicity (UDP). Phytochemical test results showed that propolis extracts from Geniotrigona thoracica and Heterotrigona itama have consistent levels of secondary metabolites, namely flavonoids, alkaloids, tanins, and phenolics. Based on the acute toxicity test results, it can be concluded that the propolis extracts from Geniotrigona thoracica and Heterotrigona itama have consistent LD50 values, exceeding 5000 mg/kg body weight, and are classified as non-toxic.
