Abstract
3-O-β-D-glucopyranosyl gouanogenin A (1), a new naturally occurring dammarane class of triterpene glucoside, has been isolated from the aerial parts of Gouania longipetala along with six known secondary metabolites 2–7. Their structure was elucidated through spectroscopic data including 1 D- and 2 D-NMR. The compounds 1 and 6 showed significant antioxidant potential in DPPH radical scavenging assay. On the other hand, the compound 4 revealed potent inhibitory potential against the enzyme urease, while 1 and 3 were significantly active.
