摘要：
The new thymol derivatives, 10-acetoxy-9-chloro-8,9-dehydrothymol, 10-acetoxy-8,9-dehydrothymol, 10-isobutyryloxy-8,9-dehydrothymol and 9-acetoxy-thymol, were isolated from flowerheads of Arnica sachalinensis and identified by their mass and NMR spectra. Furthermore, six new and five known thymol derivatives were identified as minor compounds mainly by TLC and GC-mass spectrometric analysis. (C) 1998 Elsevier Science Ltd. All rights reserved.
