A new flavonoid glycoside, xylopoillin A (1), and nine known compounds were isolated from the methanolic extracts of the leaves of Xylopia poilanei. The structure of this new compound was completely elucidated using a combination of 2D NMR techniques (COSY, NOESY, HMQC and HMBC) and HR-ESI-MS analyses. The other chemical structures of known compounds were identified by comparison of their spectroscopic and physical data with those reported in the literature. © 2009 The Japan Institute of Heterocyclic Chemistry All rights reserved.
