Abstract
The aerial parts of Hyalis argentea yielded, in addition to four known ent-kaurenes, three known guaianolides and one coumarin, the new (7R) -ent-15-oxokaur-16-en-7-ol-19-oic acid beta-glucopyranosyl ester and t hree new diterpene lactones which biosynthetically seem to be derived from ent-15-oxokaurenoic acid. The structures were determined mainly b y one- and two-dimensional spectroscopy. Copyright (C) 1997 Elsevier S cience Ltd
