Abstract
Chromatographic separation of ethanolic root extracts of Taraxacum laevigat um and Taraxacum disseminatum afforded a total of eight germacrane- and eud esmane-type sesquiterpenoids, including new compounds, 1 beta,3 beta,6 alph a-trihydroxy-4 alpha(15)-dihydrocostic acid methyl ester and its 1-O-beta-g lucopyranoside. Their structures were established by spectroscopic analyses . In addition, the structure of 4 alpha(15),11 beta(13)-tetrahydroridentin B-1-O-beta-glucopyranoside was elucidated by extensive NMR studies. (C) 200 0 Elsevier Science Ltd. All rights reserved.
