Abstract

Hyperuricemia is a metabolic disorder characterized by elevated serum uric acid levels due to excessive production or impaired excretion. Conventional therapy using xanthine oxidase inhibitors such as allopurinol is effective but may cause adverse effects with prolonged use. This study aimed to evaluate the antihyperuricemic activity of kenikir (Cosmos caudatus Kunth.) leaf infusion in a potassium oxonate-induced hyperuricemic mouse model. Phytochemical screening revealed the presence of alkaloids, flavonoids, saponins, and tannins. Twenty-five male mice were randomly assigned into five groups (n=5): negative control (0.5% NaCMC), positive control (allopurinol 100 mg/kgBW), and three treatment groups receiving 10%, 15%, and 20% infusion. Hyperuricemia was induced using chicken liver juice and potassium oxonate (300 mg/kgBW). Each mouse received 0.5 mL orally. Blood uric acid levels were measured hourly for four hours using EasyTouch GCU. Statistical analysis using the Kruskal–Wallis test showed no significant difference among groups (p=0.220). However, descriptively, the 15% concentration demonstrated the highest percentage reduction (56.77%), followed by 20% (41.28%) and 10% (38.74%), compared with allopurinol (66.01%). These findings suggest that kenikir leaf infusion exhibits potential antihyperuricemic activity and supports further investigation with optimized dosing, larger sample size, and enzymatic validation.

Abstract

This study aims to explore the antibacterial activity potential of fermented dragon fruit peel juice (Hylocereus polyrhizus) fermented using Lactic Acid Bacteria (LAB) isolated from rice washing water (Beras Mayas). The process begins with the preparation of dragon fruit peel samples, which are washed, peeled, and mashed to obtain the juice. The juice is pasteurized and inoculated with a 5% LAB starter, with the addition of a 10% sugar solution before being incubated for 3, 7, 12, and 17 days at 37ºC. pH measurements were taken during fermentation, showing a significant decrease in pH, reaching the lowest value of 3.76 on day 17. The antibacterial activity was measured using the well-diffusion method with the fermented juice at a concentration of 100%, showing a very strong inhibition zone (>20 mm) against Propionibacterium acnes on day 7. The results indicate that the pH changes during fermentation are closely related to the antibacterial activity

Abstract

Mitragyna speciosa Korth. berasal dari famili Rubiaceae yang banyak tumbuh di daratan negara-negara Asia Tenggara. Tumbuhan ini selain disebut Kratom, khususnya di daerah Kalimantan Timur dikenal juga dengan nama "Kadamba". Mitragyna speciosa Korth. belongs to the Rubiaceae family and is widely found in the mainland of Southeast Asian countries. This plant, known as Kratom, is also referred to as "Kadamba" in East Kalimantan. Kadamba has been used for generations as a traditional medicine and contains predominantly alkaloid compounds, which generally function as analgesics, antitussives, antidiarrheals, adrenergic agents, antimalarials, antibacterials, and antinociceptives. The aim of this research is to determine the isolation and identification methods for alkaloid compounds in Kadamba leaves. In this study, extraction was performed using methanol solvent, followed by fractionation using Vacuum Liquid Chromatography (VLC) and Column Chromatography (CC) with gradient eluents: 100% hexane, n-hexane : Ethyl Acetate (5:1, 1:1, 1:5), 100% Ethyl Acetate, Ethyl Acetate : Methanol (1:1, 1:5), and 100% Methanol. The compounds were then identified using Thin Layer Chromatography (TLC). The isolation process used preparative Thin Layer Chromatography (PTLC) with eluent n-hexane: ethyl acetate: 25% ammonia (6.5:3:0.5 v/v/v), and the spots were observed under UV light at 245 nm and 366 nm. The visible spots were sprayed with Dragendorff's reagent to identify the alkaloid compounds. The results showed that the UV-Vis spectrophotometric characterization of isolate B6-b had two peaks at wavelengths of 288 nm and 294 nm.
