Abstract

Antioxidants play a crucial role in neutralizing free radicals, thereby helping to prevent cell damage and maintain overall health. This study aims to evaluate the antioxidant activity of the aqueous fraction of Tetanus (Leea aequata L.) leaf extract using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. The extraction process was carried out through maceration using ethanol as a solvent, followed by aqueous fractionation. Antioxidant activity was measured based on the extract’s ability to scavenge DPPH free radicals, expressed as the IC₅₀ value. The results showed that the aqueous fraction of Tetanus leaf extract exhibited high antioxidant activity, with an IC₅₀ value of 30.23 mg/L. The total phenolic and flavonoid contents in the aqueous fraction were 460.70 mg GAE/100g and 12,621.14 mg QE/100g, respectively. These findings align with pre vious studies indicating that the ethanolic extract of Leea angulata leaves also possesses strong antioxidant activity with a similar IC₅₀ value. Therefore, the aqueous fraction of Tetanus leaf extract has the potential to be an effective natural antioxidant source and can be further developed as a raw material for health supplements or pharmaceutical products.

Abstract

Antibiotic-resistant nosocomial infections are caused by the opportunistic bacterium Pseudomonas aeruginosa. The purpose of this study is to use the disc diffusion method to assess the antibacterial efficacy of Tetanus (Leea aequata L.) leaf ethanol extract against Pseudomonas aeruginosa. The antibacterial activity was evaluated at 25%, 50%, and 75% concentrations after the leaves were extracted by maceration with 96% ethanol. The findings indicated that the antibacterial activity was depending on concentration, with respective minimum inhibition level measuring 12.97 mm, 16.7 mm, and 21.06 mm. The negative control (DMSO) displayed no inhibition zone, but the positive control (gentamicin) displayed KHM measuring 25.03 mm. The data distribution did not differ significantly, according to statistical analysis (p > 0.05). Bioactive substances that can harm bacterial cell structures, including flavonoids, alkaloids, tannins, and saponins, were thought to be responsible for this antibacterial action. According to these results, tetanus leaf extract may be used as a natural antibacterial agent and as a substitute for antibiotics in the treatment of Pseudomonas aeruginosa infections

Abstract

Free radicals play an important role in oxidative stress, which can lead to a number of degenerative diseases, including heart disease, cancer and premature aging. Natural and artificial ingredients can be used to make antioxidants. The use of synthetic antioxidants is starting to be limited because excessive use can cause negative side effects, such as the accumulation of toxins in the body. This study aims to evaluate the antioxidant activity of tetanus (Leea aequata L.) leaf extract using DPPH method. Free radicals generated during metabolism can cause cell damage and contribute to various degenerative diseases. Therefore, it is important to find effective sources of antioxidants. In this study, Tetanus leaves were extracted using 96% ethanol solvent through maceration method. Antioxidant activity was evaluated by measuring the IC50 value against DPPH radical. The results showed that tetanus leaf extract had an IC50 value of 39.484 ppm, which indicated significant antioxidant activity. These results indicate that tetanus leaf extract can function as a free radical scavenging agent, which could potentially serve as a raw material in the development of herbal medicine to prevent oxidative stress-related diseases.

Abstract

Background: The increasing use of traditional herbal medicine (jamu) for diabetes treatment in the community has been accompanied by a rise in counterfeiting practices, particularly through the addition of synthetic drugs such as glibenclamide (C₂₃H₂₈ClN₃O₅S) to enhance efficacy and sales. This poses potential health risks, thereby necessitating strict monitoring of circulating herbal products. Objective: This study aims to identify the presence of glibenclamide in three samples of antidiabetic jamu available in Medan Johor using Fourier-Transform Infrared Spectroscopy (FTIR). Method: Identification was carried out by comparing the FTIR spectra of the samples (wavenumber range 650–4000 cm⁻¹) with that of the BPFI glibenclamide standard. The characteristic functional groups of glibenclamide used as reference were 3369.5 cm⁻¹ (Amide N–H Stretching), 1714.6 cm⁻¹ (C=O Stretching), and 1155.5 cm⁻¹ (S=O Stretching). Results: The analysis showed that none of the three samples (A2, A3, A4) exhibited absorption peaks corresponding to the critical wavenumbers of glibenclamide. Therefore, the tested samples were declared free from the pharmaceutical chemical substance (PCS) glibenclamide. Conclusion: These findings indicate that the three jamu products are safe for consumption when used as directed. However, routine surveillance by the National Agency of Drug and Food Control (BPOM) remains essential to ensure the safety of herbal products on the market. Further studies using more sensitive methods such as UV-Vis spectrophotometry are recommended to verify these results.

Abstract

Diabetes mellitus and hypertension are two chronic conditions that frequently occur simultaneously and require long-term pharmacological therapy. The combination of treatments in patients with both diseases increases the potential for drug interactions, which can compromise therapeutic effectiveness and elevate the risk of adverse effects. This study aimed to evaluate the severity of drug interactions in outpatients with diabetes mellitus and hypertension at Advent Hospital Medan during the period from October to December 2023. A non-experimental descriptive study with a cross-sectional design was employed, using retrospective data from 191 outpatient prescriptions that met the inclusion criteria. Evaluation was conducted on administrative, pharmaceutical, and clinical aspects of the prescriptions, with a primary focus on identifying drug interactions using the reference database Drugs.com. The results showed that drug interactions were present in 52.4% of the analyzed prescriptions. Most interactions were classified as moderate in severity, predominantly involving pharmacodynamic mechanisms. The most frequent interacting drug combinations included metformin, glimepiride, amlodipine, bisoprolol, and candesartan. The high prevalence of drug interactions among patients with diabetes mellitus and hypertension highlights the importance of systematic prescription screening as a preventive measure. These findings can serve as a basis for developing rational drug use policies and enhancing patient safety in clinical practice.

Abstract

Andaliman leaves (Zanthoxylum acanthopodium) are a plant that has the potential to be used as a natural ingredient in the development of herbal preparations. Andaliman leaves are known to contain secondary metabolite compounds, including flavonoids, terpenoids, alkaloids, and tannins. This potential encourages the processing of Andaliman leaves into extracts which are then formulated in the form of effervescent tablets to increase practicality of use. This study aims to produce effervescent tablets of Andaliman leaf extract with good physical quality by making three formulas with varying concentrations of acid-base components. Extraction was carried out using 70% ethanol solvent, then an evaluation of the properties of the resulting granules and tablets was carried out. The test results showed that all formulas met the requirements for organoleptic tests, water content, flow time, and compressibility, but in the angle of repose test only F2 met the criteria. Tablet evaluation showed that all formulas met the organoleptic tests, hardness, friability, and dissolution time, while the uniformity and weight tests still showed discrepancies in some formulas. Overall, formula F2 is the best formula because it meets most of the evaluation parameters for granules and tablets, so it has the greatest potential to be developed as an effervescent tablet preparation from andaliman leaf extract.

Abstract

Paracetamol is a widely used analgesic–antipyretic drug; however, it exhibits poor flowability and compactibility, requiring suitable excipients in tablet formulation. This study aimed to formulate paracetamol tablets using porang tuber starch (Amorphophallus muelleri) as a filler and to evaluate the effect of its concentration on the physical properties of granules and tablets. Tablets were prepared by the wet granulation method using three concentrations of porang tuber starch: 10 mg (F1), 15 mg (F2), and 20 mg (F3). Granule evaluation showed moisture content ranging from 2.1–3.4%, flow time of 4.8–6.2 seconds, angle of repose of 25.6–30.4°, and compressibility index of 11.2–15.6%, indicating good flow and compressibility properties. Tablet evaluation demonstrated acceptable weight uniformity with deviations < 5%, hardness values of 5.1–7.8 kg, friability of 0.32–0.78%, and disintegration times of 3.4–6.8 minutes. The formulation containing 20 mg of porang tuber starch (F3) exhibited the most optimal characteristics, with the highest tablet hardness (7.8 kg) and the lowest friability (0.32%), while maintaining disintegration time within pharmacopeial limits. Therefore, porang tuber starch shows strong potential as a natural filler in paracetamol tablet formulations.
