SOME FLAVONOIDS FROM THE LEAVES OF COMBRETUM QUADRANGULARE GROWING IN VIETNAM
Main Article Content
Abstract
The leaves of Combretum quadrangulare Kurz. collected in Long An Province were chemically investigated using multiple chromatographic methods. Four compounds, 5-hydroxy-3,7,4′-trimethoxyflavone (1), ayanin (2), kamatakenin (3), and luteolin (4) were isolated and elucidated. Their chemical structures were elucidated by comparing their spectroscopic data with those in previous reports. Compounds 1 and 4 were obtained for the first time in Combretum quadrangulare.
