Abstract
The chromenes precocene I (7-methoxy-2,2-dimethylchromene) and precocene II (6,7-methoxy-2,2-dimethylchromene) extracted from Ageratum houstonianum an d A. conyzoides have been analysed by reverse-phase high-performance liquid chromatography. Separation was achieved using a Cls column eluted with a l inear gradient of acetonitrile and water, Precocenes I and II in the essent ial oils were determined to be 270 +/- 23 and 482 +/- 34 mg/mL in A, housto nianum, and 687 +/- 21 and 20 +/- 2 mg/mL in A. conyzoides, Copyright (C) 2 001 John Wiley & Sons, Ltd.
