摘要：

The flowering aerial parts of Centaurea bracteate Scop. (Asteraceae) have been studied for the: first rime. Nineteen compounds were isolated and identified, namely a sterol glucoside, two phenolic acids, three quinic acid derivative es. and 13 flavonoids. two of which, art: new natural products. Structural elucidation was performed mainly by mean of FABMS, 1D and 2D NMR spectroscopy. (C) 2001 Elsevier Science Ltd. All rights reserved.
