ALKALOID AND PHENOLIC COMPOUNDS FROM THE STEMS OF GOUANIA JAVANICA MIQ.

Five compounds were isolated from the stems of Gouania javanica Miq. collected in Dongnai province, including nuciferine (1), nuciferine N-oxide (2), lysicamine (3), vanillic acid (4), and scopoletin (5). The structures of these compounds were established by MS and NMR (1D- and 2D-NMR) spectral methods and by comparison with the published data. This is the first time these compounds were isolated from Gouania genus.
