Three new oleanane-type triterpenoidal glycosides, imbalosides A-C (1-3), were isolated from the white flowers of Impatiens balsamina. The structures of these phytochemical constituents (1-3) were elucidated through 1D and 2D Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS) data analyses followed by chemical methods. All the characterized compounds (1-3) were evaluated for their antiproliferative activity against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and BT549) and their anti-neuroinflammatory activity on the basis of inhibition levels of nitric oxide (NO) in the lipopolysaccharide (LPS)-stimulated murine microglia BV-2 cell lines.
Keywords: Impatiens balsamina; anti-neuroinflammation; balsaminaceae; cytotoxicity; triterpenoidal glycosides.
