functionality at C-9 were isolated (285, 290, 291, 293, 297, and 537), while the coisolated compounds 305 and 306 have a carbonyl group at C-9. Sample 2 exhibited
the occurrence of guaiane (786), eudesmane (792), triterpenoid (828), and monoterpenoid (876) derivatives. This species seems to be relatively uniform in chemical
composition and thus is representative of only a very small diversity.
