Abstract

Syzygium myrtifolium (red shoot leaves) is widely known for its rich phytochemical profile, particularly flavonoids, which exhibit various pharmacological properties. This study aimed to determine the total flavonoid content in the crude extract, n-hexane fraction, ethyl acetate fraction, and water fraction of red shoot leaves (Syzygium myrtifolium) using a colorimetric method with quercetin as a standard. The results revealed that the ethyl acetate fraction had the highest flavonoid content (65.781 ± 6.365 mgQE/g), followed by the crude extract (26.093 ± 0.961 mgQE/g), n-hexane fraction (18.293 ± 2.925 mgQE/g), and water fraction (12.583 ± 0.824 mgQE/g). The study also found that the solvent polarity significantly influenced the flavonoid extraction efficiency, with ethyl acetate, a moderately polar solvent, being most effective for isolating flavonoid aglycones. The n-hexane fraction contained polymethyl flavonoids, which are more soluble in nonpolar solvents, while flavonoid glycosides were more soluble in polar solvents like water and alcohol mixtures. Furthermore, the research highlights the importance of extraction methods, as the total flavonoid content in mature red shoot leaves was found to be higher than in younger leaves, likely due to increased secondary metabolite production in mature tissues. This study emphasizes the role of solvent polarity in flavonoid extraction and provides insights into the phytochemical composition of S. myrtifolium leaves for potential applications in natural product research.

Abstract

Background: The global human population continues to grow rapidly, leading to increasing urban waste and environmental contamination. One emerging and promising approach to mitigating this pollution is zooremediation, which utilizes animals as biological agents for environmental cleanup. This review aims to critically assess the effectiveness of various animal species in removing specific classes of pollutants, with particular attention to their mechanisms of action—zooextraction, zootransformation, and zooaccumulation—and the environmental conditions under which they operate. Effectiveness is evaluated based on pollutant removal efficiency, adaptability to contaminated environments, and ecological safety. Methods: Through systematic literature analysis, we identified key species, including Geukensia demissa, Daphnia magna, and Anadara granosa, which demonstrated measurable success in the remediation of aquatic environments contaminated with heavy metals and organic pollutants. Additionally, soil-dwelling nematodes such as Caenorhabditis elegans and Cephalobus persegnis play critical roles in hydrocarbon degradation and in enhancing microbial synergy in polluted substrates. These findings highlight the diverse functional capacities of animals in bioremediation efforts. The methodology employed in this study is a comprehensive literature review, focusing on peer-reviewed articles published over the last two decades. Results: This review synthesizes findings related to pollutant types, animal species used in zooremediation, remediation outcomes, and ecological impacts. By critically examining existing studies, the evaluation identifies trends, gaps, and challenges in the application of zooremediation. Conclusion: Future research should focus on understanding the long-term impacts, optimizing protocols, and safeguarding both ecological and animal health to fully realize the potential of zooremediation in managing environmental pollution on a global scale.

Abstract

Background: Acrolejeunea fertilis (liverwort) is known for having various potential natural products. However, its abundance is limited, and its secondary metabolites have not been extensively investigated. The in vitro culture technique might enhance its biomass. Methods: This study aimed to investigate the metabolite profile of A. fertilis from Kebun Raya Cibodas grown in situ and in vitro. The bioactivity, including antioxidant, total phenolic, and flavonoid content and antibacterial activity, was also evaluated. The in vitro culture of A. fertilis used ½ MS media with the addition of 0,1 mg/L of 2,4-D and one mg/L of Kinetin. Methanol and n-hexane were used for extraction. Gas Chromatography-Mass spectrometry (GC-MS) is used for metabolite profiling. Results: The optimum IC50 value from n-hexane extract is 68,18±2,65 mg/L. The highest yield of total phenolic and flavonoid content from in situ methanol extract, which resulted in 130,68±0,002 µgGAE/gr and 5,97±0,01 µgQE/gr, respectively. Antibacterial activities were evaluated by measuring the zone of inhibition for S. aureus and E. coli. The optimum area measured from in situ n-hexane extract was 23,91±1,54 and 13,08±0,23 cm, respectively. Conclusions: These findings carry important implications for the further development of natural products obtained from liverwort regarding its potential as a bioactive compound.
