PHYTOCHEMICAL PROFILING OF PREMNA ODORATA: ISOLATION AND STRUCTURE OF TRITERPENOIDS ANDFLAVONOIDS FROM SEEDS IN PHU YEN, VIETNAM

Abstract

Phytochemical exploration of the seeds of Premna odorata, sourced from Phu Yen province, Vietnam, has yielded significant insights into its chemical composition. This investigation led to the isolation of four compounds: two triterpenoids, identified as arjunolic acid and ursolic acid, and two flavonoids, characterized as cirsiliol and luteolin. The structures of these isolates were meticulously determined through the application of advanced spectroscopic methods, including electrospray ionization mass spectrometry (ESI-MS) and nuclear magnetic resonance (NMR) spectroscopy. These findings represent a new contribution to the phytochemical profile of P. odorata, broadening the knowledge of its molecular diversity and underscoring its potential as a reservoir of biologically relevant natural products. This study enhances the foundation for further research into the therapeutic and ecological significance of this species within the domain of organic chemistry and natural products.
