Chemical constituents from Gendarussa vulgaris Nees and their chemotaxonomic significance

The phytochemical investigation on the aerial parts of Gendarussa vulgaris led to the isolation of one new triterpenoid derivative gvterpennoid B (1), one new natural product 3-(2-hydroxy-4,5-dimethoxyphenyl)propanoic acid (9), together with four known monoterpenoids (2-5) and three known phenylpropanoids (6-8). Structure elucidation of these compounds was performed based on NMR data and MS. Known metabolites (2-8) were isolated from the family Acanthaceae for the first time. Furthermore, the chemotaxonomic significance and plant distributin of the isolates were also discussed in this thesis.
