ABSTRACT
This study aimed to determine the phytochemical screening of the Methanolic Bark Extract of Ziziphus talanai using Thin Layer Chromatography (TLC). The phytochemical screening revealed the presence of Glycosidic Flavonoids, Steroids, Anthraquinones, Anthrones, Coumarins, Alkaloids, Phenol, Tannins, Flavonoids, Higher Alcohol, and Essential Oils. The increasing prevalence of mosquito-borne diseases such as dengue necessitates the fever, chikungunya, development of and novel Zika and virus effective larvicides to control the population of Aedes aegypti, the primary vector of these diseases (Ryan & Carlson, 2019). This study investigates the potential larvicidal activity of methanolic bark extract of Ziziphus talanai against Aedes aegypti larvae. The research aims to evaluate the efficacy of the extract in terms of mortality rate through bioassay methods. Phytochemical analysis of the extract is conducted to identify the active compounds responsible for larvicidal effects. Preliminary results indicate that Ziziphus talanai methanolic bark extract exhibits significant larvicidal properties, with notable mortality rates observed within 24 hours of exposure. These findings suggest that Ziziphus talanai could be a promising natural larvicide, offering an eco-friendly alternative to synthetic chemical larvicides.
