Two new compounds isolated from the aerial parts of blume.

Two new aromatic compounds, namely gastupdin A (), and gastupdin B (), together with three known compounds, arundin(), phomosines B () and monocillin IV (), were isolated from the aerial parts of Blume. The structures of the new compounds were confirmed through spectral analyses including NMR, HR-ESI-MS, ECD, UV, and IR. All isolated compounds were evaluated for their neuroprotective effects against 6-hydroxydopamine-induced cell death in Human Neuroblastoma Cells, with curcumin as the positive control, however, the activity of all compounds was weaker than the positive control, showing no significant activity.
