Abstract

Natural ingredients can have extraordinary potential as alternative medicines due to their accessibility and cost-effectiveness. Application of these ingredients should consider solubility and permeability, which determine the success of pharmaceutical characteristics formulation and biological activity indication. In this context, physical manipulation, specifically particle size reduction, is an effective strategy to address these issues. Previous research has explored active compounds in the stilbenoid group, found in the outer skin, hard shell, and endosperm of melinjo (Gnetum gnemon L.) seeds, functioning as antioxidant. Based on the potential as antioxidant, stilbenoid compounds, including resveratrol, contained in melinjo seed hardshell have shown significant pharmacological effects. Therefore, this research aimed to investigate the potential of melinjo seed hardshell extract as a natural antioxidant alternative by modifying the particle size through a grinding process to obtain nanoparticles. The analysis was carried out using ball milling to enhance the solubility of melinjo seed hardshell extract by increasing the saturated solubility and surface area of the particles. The results showed that the total phenol content and the antioxidant power increased significantly (p < 0.05) after ball milling. Melinjo seed hardshell nanoextract is reported herein as a promising source of natural antioxidant from local Indonesian plants.

Abstract

Dandruff was an anomaly of scalp caused by abnormal growth of Pityrosporum ovale. Ketoconazole and sulfuric compounds known as antifungal, include antifungal against Pityrosporum ovale. One of medicinal plant that has polysulfide compounds was Singawalang (Petiveria alliacea L.). Activity of ethanol extract and fraction of singawalang roots tested using microdilution broth method appropriate to Clinical and Laboratory Standard Institute (CLSI) standard, then growth profiles determined by colony count. Microdilution test results showed that Singawalang roots extract has antifungal activity against Pityrosporum ovale with Minimum Inhibition Concentration (MIC) 16 μg/mL and Minimum Fungicidal Concentration (MFC) 64 μg/mL. Fraction that has highest activity against Pityrosporum ovale was n-hexane fraction of Singawalang roots with MIC 16 µg/ml dan MFC 128 μg/mL. The higher activity of the extract predicted that there were some polysulfide compounds have synergic activity. Key words : singalawang roots, polysulfide, Pityrosporum ovale ABSTRAK Ketombe adalah suatu keadaan anomali pada kulit kepala disebabkan jamur Pityrosporum ovale dalam jumlah diatas normal. Selama ini antijamur yang digunakan adalah ketokonazol. Selain itu, senyawa sulfur juga diketahui aktif terhadap jamur. Salah satu tanaman yang telah diteliti mengandung senyawa polisulfida adalah tanaman singawalang (Petiveria alliacea L.). Penelitian aktivitasnya terhadap Pityrosporum ovale dilakukan dengan Broth Microdilution sesuai standar Clinical and Laboratory Standard Institute (CLSI). Konsentrasi Hambat Minumum (KHM) terkecil ada pada ekstrak dan fraksi n-heksan, yaitu 16 μg/mL, seperempat dari aktivitas ketokonazol. Konsentrasi Fungisidal Minimum (KFM) terkecil ekstrak adalah 64 μg/mL, dan pada fraksi n-heksan ekstrak etanol akar singawalang dengan konsentrasi 128 μg/mL. Diduga aktivitas antijamur lebih kuat pada ekstrak karena adanya kombinasi aktivitas beberapa senyawa polisulfida yang bekerja sinergis. Kata kunci : Akar singawalang, polisulfida, Pityrosporum ovale

Abstract

Obat tradisional seperti jamu masih sering digunakan oleh masyarakat Indonesia untuk mengatasi berbagai keluhan dari ringan hingga berat. Namun dalam hal penggunaan obat berbasis bukti ilmiah (evidence basedmedicine), obat tradisional tidak dianjurkan sebagai pilihan dalam pengobatan mengingat keterbatasan data penelitian. Oleh karena itu akan dilakukan kajian mengenai potensi berbagai tanaman obat yang sering digunakan dalam jamu terutama untuk terapi osteoporosis berdasarkan data ilmiah yang telah ada hingga saat ini. Data ilmiah yang digunakan hanya yang bersumber dari literaturr primer. Dari penelusuran pustaka yang dilakukan, semua tanaman berpotensi untuk digunakan dalam terapi osteoporosis terutama cengkeh, kacang hijau, kayu manis, lada hitam, sambiloto, bawang Bombay, mengkudu, dan kacang panjang, walau masih perlu dilakukan penelitian lebih lanjut.

Abstract

Edible bird's nests (EBNs) from Aerodramus fuciphagus have been traditionally used in Asia for their various health benefits, including antioxidant properties. Previous studies have reported antioxidant activity in EBN water extracts using methods like ABTS and ORAC. However, the antioxidant activity can vary significantly depending on factors such as the source of EBN, extraction methods, and the specific assay used. This study aimed to comprehensively evaluate the antioxidant potential of EBN water extract using a range of in vitro assays. The antioxidant activity was assessed using four different methods: 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, nitric oxide (NO) radical scavenging, ferric reducing antioxidant power (FRAP), and cupric reducing antioxidant capacity (CUPRAC). Results demonstrated that the EBN water extract exhibited moderate NO radical scavenging activity with an IC50 value of 116.86 μg/mL. While weak activity was observed in the DPPH assay, the FRAP and CUPRAC assays showed promising antioxidant potential with an ascorbic acid equivalent (AAE) of 4.567±0.30 and 3.487±0.095 μg AAE/mL, respectively. These findings suggest that the antioxidant activity of EBN water extract may be primarily attributed to its protein content. However, further investigations are warranted to elucidate the specific mechanisms of action and isolate the bioactive compounds responsible for the observed antioxidant effects. These findings have implications for the development of EBN-based functional foods, nutraceuticals, and cosmeceuticals with enhanced antioxidant properties.

Abstract

Cases of illegal drugs and drug abuse in the elementary school community in Indonesia is increasingly massive and alarming. An innovation to protect elementary school students from that situation is through the colaboration of academics from Bandung Institute of Technology with FDA in Palu in the form education of anti-drug abuse for elementary school students through quartet card media. The aim of the study was to determine the effect of the education on anti-drug abuse knowledge in fifth grade students in Palu City. The research method used pre-experimental design with the design of one group pretest-posttest on three elementary schools which were representatives of three ranks namely; good, quite good and not good based on the results of the Smart-Accurate Quiz FDA in Palu for elementary school level in 2017. The sampling technique used purposive sampling. Observation of knowledge of elementary students using questionnaires that have been tested for validity and reliability had been carried out. The pretest and posttest were conducted before and after education. The comparison of pretest and posttest data in each elementary school was analyzed using paired T test whereas for all elementary school data analyzed using the Wilcoxon test with hypotheses. There was an influence of anti-drug abuse education through quartet card media on anti-drug abuse knowledge in fifth grade students in Palu City. The results showed that there was an influence of education on anti-drug abuse knowledge in fifth grade students from elementary school representatives “good and quite good ranking” with p values of 0.005 and p ≤ 0.001, while in elementary schools representatives “not good ranking”, the education did not influence their knowledge with a p value of 0.149. Analysis of the Wilcoxon test in all elementary schools showed a p value p ≤ 0,001, which meant that education had an influence on the knowledge of fifth grade students in elementary schools in Palu City.
