Baccharis articulata Lam

Baccharis gaudichaudiana D. C. ( Chilca melosa ) and Baccharis articulata (Lam.) Pers. ( Carquejilla ) are used traditionally as decoctions or infusions as an antidiabetic remedy in Paraguay [13],... 

At one time, B. gaudichaudiana was taxonomically classified as a varietal form of Baccharis articulata (Lam.) Pers., a widely utilized medicinal plant in several South American countries. However, when B. articulata was examined for its constituents, neither gaudichaudiosides A-F nor any labdane diterpenoids were found to be present. These observation thereby offer chemotaxonomic substantiation for classifying these two taxa as separate species (97). 

The UV/Visible spectra of populations of two species, Baccharis articulata (Lam.) Pers. and B. trimera can be seen in Figure 2. In this figure it is difficult to distinguish which spectrum corresponds to which species, but the resolution is greater when PCA is applied (Figure 3) and different coordinates can be seen for the corresponding populations of one species or another.
