, p. 3587 - 3590 (2007/10/02)
The aerial parts of Hoffmannia strigillosa afforded, in addition to known compounds, seven new diterpenes, five clerodanes, two ent-phyllocladanes (8,13-bis-epi-ent-kauranes) and two new monoterpenes.The structures were elucidated by high field NMR spectroscopy.
GUAIANOLIDES AND HELIANGOLIDES FROM HYMENOPAPPUS NEWBERRYI
Bohlmann, F.,Zdero, C.,Turner, B. L.
, p. 1055 - 1058 (2007/10/02)
The aerial parts of Hymenopappus newberryi afforded two heliangolides, two thymol derivatives, as well as two new guaianolides and a trans,trans-germacranolide closely related to hiyodorilactone A.Furthermore, the ent-kaurene derivative abbeokutone was present.These results are of chemotaxonomic interest.Key Word Index - Hymenopappus newberryi; Compositae; sesquiterpene; lactones; guaianolides; heliangolides; ent-kaurene derivative; chemotaxonomy.
