Distribution Baccharis

Morales etal. [32] isolated another compound of this type, a new ent-clerodane fiiranoditerpenoid named bolivianol, Fig. (9) from Baccharis boliviensis (Wedd.) Cuatr. B. boliviensis, widely distributed from Peru across Bolivia to Chile and Argentina, also afforded known e r-clerodane derivatives [33],... 

Baccharis L. is an exclusive American genus comprising approximately 500 species. Its distribution area covers the whole of South America and continues northwards up to the south of USA including the Atlantic coast up to Massachusetts, although its presence is greater in the intertropical and subtropical zones (Cuatrecasas, 1%7 Muller, 2006). Several... 

As yet, no systematic study focusing on generic-level diterpenoid distribution patterns has been reported for the Compositae. Consequently, little is known about how diterpenes vary within groups of related species. As a partial remedy for this deficiency, diterpene interspecific variation is described for representative genera of the major diterpene-producing tribes Eupatorieae Brickellia, Stevia), Astereae Baccharis), Inuleae (Helichrysum), and Heliantheae (Helh anthus, Montanoa). 

Diterpenoid distribution was contrasted to that of other terpenoids for the two genera, Baccharis and Helianthus. These two taxa were selected for a more detailed examination, because their chemistries represented the two major types of diterpene complements a bicyclic labdane/clerodane type Baccharis) and a polycyclic type Helianthus).
