Phytochemical Profiling of Aqueous Leaf Extract of Vernonia amygdalina: And Its Polycyclic Aromatic Hydrocarbon (PAH) Content

This study focuses on the phytochemical profiling of the aqueous leaf extract of Vernonia amygdalina, a plant recognized for its extensive medicinal applications in traditional medicine. The objective was to identify and quantify key phytochemicals using Polycyclic Aromatic Hydrocarbons (PAH) analysis, which offers a comprehensive approach to assess the chemical composition of plant extracts. The leaves were collected, dried, and subjected to aqueous extraction to maximize the retention of bioactive compounds while ensuring environmental sustainability. The extraction process was optimized to enhance yield and efficacy, followed by a detailed phytochemical screening using various analytical techniques. The results demonstrated the presence of a diverse array of phytochemicals, including flavonoids, alkaloids, tannins, and phenolic compounds, which are associated with various pharmacological effects. Quantitative analysis revealed that the extract is particularly rich in flavonoids, known for their antioxidant properties, and alkaloids, recognized for their potential therapeutic effects against a range of diseases.
