Jaensch, M.,Jakupovic, J.,Sanchez, H.,Dominguez, X. A.
, 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.
