Abstract

Beetroot (Beta vulgaris L.) is a cultivated plant with medicinal properties, containing bioactive compounds such as flavonoids, tannins, and saponins that are known to exhibit antibacterial activity. Methicillin-Resistant Staphylococcus aureus (MRSA) and Streptococcus mutans pose significant clinical challenges due to antibiotic resistance and their association with nosocomial infections and dental caries, respectively. This study aimed to evaluate the antibacterial activity of ethyl acetate extract of beetroot against MRSA (ATCC 43300) and Streptococcus mutans (ATCC 25175) using the disc diffusion method. Simplicia characterization revealed a water content of 13.15%, water-soluble extract of 42.5%, ethanol-soluble extract of 44.8%, total ash of 12.56%, and acid-insoluble ash of 1.81%. Phytochemical screening confirmed the presence of alkaloids, flavonoids, terpenoids, steroids, saponins, and tannins. Antibacterial testing at concentrations of 125, 250, and 500 mg/ml showed inhibition zones of 8.3, 8.7, and 11.5 mm against MRSA, and 7.5, 8.4, and 10.3 mm against S. mutans, respectively. The minimum inhibitory concentration (MIC) was determined to be 125 mg/ml for both bacterial strains. These findings suggest that the ethyl acetate extract of beetroot possesses promising antibacterial activity ranging from moderate to strong category.

Abstract

The maximum allowable concentrations of nitrite and nitrate in drinking water are regulated by the Regulation of the Ministry of Health of the Republic of Indonesia No. 492/Menkes/Per/IV/2010. Variations in environmental conditions and agricultural activities may influence the levels of these contaminants in different water sources. This study aimed to determine nitrite and nitrate concentrations in drinking water obtained from several sources in Medan City. Eight samples were collected, consisting of municipally treated water from two drinking water companies, two well water samples, two commercially bottled water brands, and boiled well water. Quantitative analysis was performed using visible spectrophotometry at a wavelength of 536 nm with a Shimadzu UV mini-1240 spectrophotometer. Nitrite concentrations ranged from 0.0273 to 0.6452 mg/L, while nitrate concentrations ranged from 0.0148 to 3.9431 mg/L. All measured levels were below the maximum permissible limits. The validated analytical method demonstrated acceptable accuracy and precision, indicating its suitability for routine monitoring of drinking water quality. Differences in water source and management practices were found to influence nitrite and nitrate concentrations.

Abstract

Diarrhea remains a major global health challenge caused by pathogenic bacteria including Escherichia coli, Salmonella typhi, Staphylococcus aureus, and Bacillus cereus. African leaf (Vernonia amygdalina Delile.) contains bioactive compounds such as flavonoids, saponins, tannins, and alkaloids with recognized antibacterial properties. This study determined the Minimum Inhibitory Concentration (MIC) of ethanol extract of V. amygdalina prepared by Ultrasonic-Assisted Extraction (UAE) at three extraction times (5, 15, and 30 minutes) against four diarrhea-causing bacteria using the disc diffusion method. Extraction yields were 8.8%, 10.45%, and 11.9% for UAE at 5, 15, and 30 minutes, respectively. Antibacterial testing at concentrations ranging from 300 to 1.56 mg/mL demonstrated predominantly moderate inhibition zones (5–10 mm), with some concentrations reaching the strong category (10–20 mm). The MIC for B. cereus and S. aureus was 1.56 mg/mL across all extraction times. For S. typhi, the MIC was 1.56 mg/mL (5 and 30 min UAE) and 12.5 mg/mL (15 min UAE). For E. coli, the MIC was 6.25 mg/mL (5 min UAE) and 1.56 mg/mL (15 and 30 min UAE). One-way ANOVA confirmed statistically significant differences among concentrations (p < 0.05). The 30-minute UAE produced the highest yield and generally superior antibacterial activity, supporting its selection as the optimal extraction condition. These findings highlight the potential of V. amygdalina ethanol extract as a natural antibacterial agent for diarrheal disease management.

Abstract

Bay leaf (Syzygium polyanthum (Wight) Walp.) is a traditional medicinal plant containing phenolic and flavonoid compounds with potential antioxidant properties. Free radicals contribute to various degenerative diseases, highlighting the need for safe and effective natural antioxidants. This study aimed to evaluate the antioxidant activity of ethanolic extract of bay leaves using the DPPH method and to determine its total phenolic and flavonoid contents. This experimental laboratory study employed maceration extraction using 96% ethanol. Antioxidant activity was assessed by the DPPH radical scavenging assay at 517 nm and expressed as IC₅₀ value. Total phenolic content was determined using the Folin–Ciocalteu method at 765 nm and expressed as mg gallic acid equivalents (GAE)/g extract, while total flavonoid content was measured using the AlCl₃ colorimetric method at 430 nm and expressed as mg quercetin equivalents (QE)/g extract. The results showed that the ethanolic extract exhibited a strong antioxidant activity with an IC₅₀ value of 33.43 ppm. The total flavonoid content was 14.4992 mg QE/g extract (1.4499%) with excellent linearity (r² = 0.99747), while the phenolic calibration curve showed good linearity (r² = 0.99045). In conclusion, the ethanolic extract of S. polyanthum leaves demonstrates strong antioxidant activity supported by its phenolic and flavonoid contents, indicating its potential as a natural antioxidant source.

Abstract

Diabetes mellitus is a chronic disease that impairs wound healing due to oxidative stress and prolonged inflammation. Bay leaf (Syzygium polyanthum) contains bioactive compounds with potential therapeutic effects in promoting tissue repair. This study aimed to evaluate the effectiveness of topical bay leaf extract gel on macroscopic wound healing in alloxan-induced diabetic rats. This experimental in vivo study used 30 male rats divided into six groups: normal control, negative control, positive control (Bioplacenton), and treatment groups receiving extract gel at concentrations of 2.5%, 5%, and 10%. Diabetes was induced using alloxan, followed by burn wound creation and topical treatment for 14 days. The results showed that treatment groups exhibited faster wound healing compared to the negative control. The 2.5% and 10% extract gel groups demonstrated more optimal wound closure, comparable to the positive control by day 14. These findings indicate that flavonoid and phenolic compounds in bay leaf contribute to antioxidant and anti-inflammatory activities, supporting tissue regeneration. In conclusion, bay leaf extract gel is effective in accelerating wound healing in diabetic conditions. Further studies are recommended to investigate histopathological changes and molecular mechanisms.
