Abstract
From the leaves ofGoniothalamus tenuifolius, a new natural product namely 3′-hydroxy-3,5,7,4′-tetramethoxyflavone (1) was isolated, along with seven other known compounds (2–8). Each of these isolates was evaluated for free radical scavenging activity on the DPPH decoloration test. The data obtained in this study suggested that theortho 3′,4′-diphenolic structure was essential for the activity of these flavonol derivatives.
