A Characterization and Analysis of Bioactivity in Lonicera maackii Flowers and First-Growth Leaves.

Bush Honeysuckle (Lonicera maackii) is a widespread invasive species on the Maryville University campus. This rapidly growing honeysuckle negatively impacts biodiversity, damages watersheds, and out-competes native MO plant species. This project serves as a subset of the Maryville University Honeysuckle project, which aims to remove the invasive plant, produce a sustainable product from the biomass for the university, and replant native species to restore balance to the local ecosystem. The goal of this project was to research the chemical components of the honeysuckle flowers and first growth leaves. Specifically, we asked: 1. Are these bioactive components useful for medicinal purposes? 2. Do these compounds possess anti-microbial properties? 3. Are these anti-microbial properties adapted to the presence of microbes in the soil, contributing to the plant’s invasive nature? Collected materials were dried and crushed prior to extraction. Soxhlet extractions were performed with either deionized water or ethanol. Following extraction multiple chemical tests for bioactivity were performed, including Molisch’s test, a Ferric Chloride test, Wagner’s test, a Frothing test, and Salkowki’s test. Finally, LC-ESI-MS as well as GC-MS was utilized to better characterize the extracts. The results showed a number of peaks indicating the presence of bioactive compounds. The chromatograms obtained provided the retention times of the various components. Additionally, the biochemical assay conducted revealed the presence of several classes of bioactive compounds which show promising medicinal properties.
