Abstract
From the aerial parts of Hieracium gymnocephalum the new triterpene, 21 alp ha-hydroxy-taraxasterol and flavone diglycosides luteolin 7-O-alpha-L-rhamn osyl(1 --> 6)-beta-D-glucoside and luteolin 7-O-beta-D-xylosyl(1 --> 6)-bet a-D-glucoside were isolated, as well as further common triterpenes, phenoli c acids and flavones. The structures were established from spectral data (U V, MS,H-1 and C-13 NMR). (C) 1998 Elsevier Science Ltd. All rights reserved .
