TLDR
Two new diterpenes, 3α, 18-dihydroxy-13-furyl-ent -labda-8(17)-ene and 3α-hydroxy-18-angeloyloxy- 13-fural- ent -labelda- 8(17) were isolated from the leaves of Gutierrezia grandis as discussed by the authors, their structures were determined by mass spectral, IR, 1 H NMR and 13 C NMR data was well as chemical evidence.About:

Neue labdan-derivate aus Gutierrezia-arten
TL;DR: The aerial parts of Gutierrezia lucida afforded three new diterpenic acids, all closely related to agathic acid and those of G. mandonii also three diterpene derivatives, which again are labdane derivatives, are elucidated by spectroscopic methods and some chemical transformations.
