ANTIOXIDANT POTENTIALS OF PARAMIGNYA TRIMERA LEAVES
Main Article Content
Abstract
Paramignya trimera or “XAO TAM PHAN,” a traditional medicinal plant native to Vietnam, has been utilized in Asian countries for its therapeutic properties. The primary objective of this research was to isolate bioactive compounds from the leaves of P. trimera using a bio-guided routine based on antioxidant properties. The free radical DPPH scavenging activity of various extracts was evaluated, and the most active extract, extract EA, was selected for further chemical investigation. Three compounds, namely luteolin (1), scopoletin (2), and ostruthin (3), were isolated from the extract EA of Paramignya trimera leaves. The chemical structures of these compounds were elucidated by comparing their spectroscopic data with previously reported literature data. Upon the free radical DPPH scavenging activity, compound 2 exhibited strong activity with an IC50 value of 7.1 mM.
