Molecular phylogenetics and character evolution of the “sacaca” clade: Novel relationships of Croton section Cleodora (Euphorbiaceae)

“…The effectiveness of C. cajucara at reducing lipid and glucose levels has been demonstrated in the laboratory by several authors (Farias et al, 1996(Farias et al, , 1997Costa et al, 1999;Grynberg et al, 1999;Hiruma-Lima et al, 1999b;Maciel et al, 2000;Silva et al, 2001aSilva et al, , 2001b. Croton cajucara has also been shown to contain high levels of linalool, an alcohol used in the perfume industry (Araújo et al, 1971), which has raised much interest in this species among researchers in recent years (Moreno et al, 2009). Although Müller (1873) implied a close relationship between C. cajucara, C. heterocalyx Baill., and C. sphaerogynus Baill.…”

“…Croton L., the second largest genus of Euphorbiaceae, is an important pantropical lineage with several species that are employed in traditional medicine practices in Africa, Asia, and South America (Moreno et al, 2009;Salatino et al, 2007). The genus has over 1200 species (Govaerts et al, 2000), ranking it as the 11th largest angiosperm genus (Frodin, 2004).…”

“…by placing them together in his key, we are aware of no other publication until Webster (1993) that suggests what the closest relatives of C. cajucara might be. All phytochemical and pharmacological investigations within section Cleodora had been confined to C. cajucara until Moreno et al (2009), who tested C. heterocalyx based on the hypothesis of close relationship implied by the taxonomic treatment of Webster (1993), discovered that it also contains linalool and has antimicrobial properties. Moreno et al (2009) found 17 chemical compounds in common between the essential oils of C. heterocalyx and those found in C. cajucara by Lopes et al (2000).…”

Herein we provide a more comprehensive hypothesis of the phylogenetic relationships of the species related to C. cajucara and C. heterocalyx, which may be useful for further bioprospecting in this group.…”
