8-9' linked neolignans with cytotoxicity from Alpinia conchigera.


Five new 8-9' linked neolignans conchigeranals A-E (1-5), together with three known compounds galanganal (6), galanganols A (7) and B (8), were isolated from the whole plant of Alpinia conchigera. Their structures were established by spectroscopic analysis, including 2D-NMR spectroscopic techniques. Cytotoxicities of compounds 1-8 were tested against two… (More)
