title: Indole alkaloid glycosides from the aerial parts of Strobilanthes cusia.
abstract: Three indole alkaloid glycosides, strobilanthosides A-C (1-3), two known indole alkaloid glucosides (4 and 5), and five phenylethanoid glycosides (8-10) were isolated from the aerial parts of Strobilanthes cusia. The structures of the new compounds were elucidated by spectrometric analysis, and the absolute configurations of 1 and 2 were established by ECD spectrocsopy. N'-β-d-Glucopyranosylindirubin (5) showed weak antibacterial activity (MIC 62.5-125 μM) against Staphylococcus aureus.
