Abstract
|
|
|
|
Five aromatic compounds, of which two are new glucosides, and six flavonols were isolated and identified for the first time from the flower heads and aerial shoots of Helichrysn conglobatum (Asteraceae). Their structures were established on the basis of chemical and spectroscopic methods including UV, MS, ID - and 2D-NMR. Some fractions and isolates were screened for anti-microbial activities. This is the first report of the isolation of the chemical constituents of this species.
