Abstract

The increasing prevalence of antibiotic-resistant bacteria poses a critical global health concern, necessitating the exploration of novel antibacterial solutions. Endophytic bacteria, which colonize plant tissues without causing harm, have gained attention as potential sources of bioactive metabolites. This study aimed to isolate and characterize endophytic bacteria from Bambusa vulgaris leaves and evaluate their antibacterial potential against pathogenic microorganisms. Leaf samples were collected from Bekasi, West Java, and subjected to a surface sterilization process prior to bacterial isolation. A total of 12 bacterial strains were successfully obtained and screened for antibacterial activity against Bacillus subtilis, Propionibacterium acnes, Pseudomonas aeruginosa, and Staphylococcus epidermidis using the agar well diffusion assay. Three isolates exhibited notable inhibitory activity, with P8 demonstrating the strongest antibacterial effects against B. subtilis, P. acnes, and S. epidermidis. The two most potent isolates, P8 and K3, were characterized via 16S rRNA gene sequencing. Genomic DNA extraction was performed, followed by Polymerase Chain Reaction (PCR) amplification using the universal primers 27F (5′-AGAGTTTGATYMTGGCTCAG-3′) and 1492R (5′-GGTTACCTTGTTACGACTT-3′). Sequencing and The Basic Local Alignment Search Tool (BLAST) analysis confirmed that isolate P8 exhibited 100% similarity to B. subtilis strain LZH-H1, whereas isolate K3 shared 99.85% similarity with Pantoea stewartii subsp. indologenes strain SR2-12. These findings suggest that endophytic bacteria from B. vulgaris endohytic bacteria hold promise as potential sources of antibacterial compounds. Further research is necessary to purify and characterize these bioactive metabolites for potential pharmaceutical applications.

Abstract

Rutin is a compound derived from flavonoids. Rutin is a quercetin glycoside with a disaccharide consisting of glucose and rhamnose. Rutin is known to have activity as an antioxidant, anti-radical, estrogenic, anti-inflammatory, antiviral, antitumor, cytotoxic and protects against organ damage. The manufacture of herbal medicines must first go through a standardization process. This review was conducted to identify the rutin contained in an extract by means of Visible Light, KLT, HPLC, and LCMS. This research uses the literature review method by collecting and identifying relevant research data sources or articles published online, through the Google Scholar web database and Science Direct.

Abstract

Male infertility has occurred rapidly in the last few decades, primarily in developing countries. An antioxidant, hesperetin is a flavonoid that is found in abundance in orange peels. The aims of this research were to determine the effect of hesperetin on blood sugar levels, spermatozoaquality, and spermatozoa quantity. The research structure included induction of diabetes mellitus and treatment for 8 weeks, followed bydetermination of blood sugar levels, spermatozoa quality, and spermatozoa quantity. Hesperetin has the ability to restore blood sugar levels, spermatozoa quantity, seminiferous tubules diameter, and testicular weight, volume, and germinal epithelial layer thickness with significant difference from the normal control group. Hesperetin did not fully restore spermatozoa motility, viability, and morphology with significant difference from the normal control group, nor from the positive control group. However, overall, hesperetin decreased blood glucose levels, increased spermatozoa quantity, and improved the spermatozoa quality in alloxan-induced diabetes mellitus mice. Dose-dependent activity was observed with the optimum dose at 200 mg/kg body weight.

Abstract

Bacterial infections remain a major global health concern, particularly with the growing incidence of antibiotic resistance. This situation has encouraged the search for alternative antibacterial agents derived from natural sources, including essential oils extracted from cinnamon bark. This review article aims to summarize current findings on the chemical characterization of cinnamon bark essential oil and the compounds responsible for its antibacterial activity, providing a foundation for its potential development as a natural antibacterial agent. Literature selection was conducted using specific inclusion and exclusion criteria, covering original research published between 2015 and 2025 and retrieved from PubMed and Google Scholar using the keywords “essential oil,” “Cinnamomum burmanii,” “bark,” and “antibacterial.” Based on this screening process, seven research articles met the established criteria. The reviewed data indicate that cinnamaldehyde is the predominant component of cinnamon bark essential oil and plays a major role in its broad spectrum antibacterial activity, including against resistant bacterial strains.

Abstract

Antimicrobial resistance is a global threat that drives the search for new antimicrobial agents derived from natural sources. Temulawak (Curcuma xanthorrhiza) contains two major active compounds, xanthorrhizol and curcuminoid, known for their antimicrobial properties. This review aims to analyze and compare the antimicrobial potential of these compounds to determine the most prospective candidate for development as an active natural antimicrobial agent in Indonesia. A systematic literature review was conducted using the PRISMA guideline on articles published between 2015 and 2025, obtained from Google Scholar and PubMed. Of the 251 articles identified, 10 met the inclusion criteria and were analyzed. The results indicate that xanthorrhizol exhibits stronger and broader antimicrobial activity, with a Minimum Inhibitory Concentration (MIC) of 16 µg/mL, inhibition zones of 12–14 mm, and inhibition rates exceeding 90% against Candida albicans and Enterococcus faecalis. In contrast, curcuminoid shows variable activity (inhibition zones of 0–16 mm) and its effectiveness increases after photodynamic activation (Photodynamic Therapy, PDT) through the formation of Reactive Oxygen Species (ROS). In conclusion, xanthorrhizol is more promising as a primary natural antimicrobial agent, while curcuminoid serves as a complementary compound to enhance antimicrobial effectiveness.
