A Molecular Phylogenetic Study of Arnica (Asteraceae): Low Chloroplast DNA Variation and Problematic Subgeneric Classification
Abstract DNA sequences from five chloroplast DNA regions (the rpl16 and rps16 introns and the psbA–trnH, ycf4–cemA, and trnT–L spacers), and the nuclear ribosomal internal and external transcribedExpand

Screening for anti-inflammatory activity of 12 Arnica (Asteraceae) species assessed by inhibition of NF-kappaB and release of human neutrophil elastase.
Several species in the genus Arnica have been used in traditional medicine to treat inflammatory-related disorders. Extracts of twelve Arnica species and two species closely related to arnica ( LayiaExpand

Secondary chemistry and ribosomal DNA data congruencies in Arnica (Asteraceae)
To investigate possible congruencies between DNA sequence data and secondary chemistry, we compared nuclear ribosomal DNA (nrDNA) sequence data, sesquiterpene lactone (STL) contents, and cytometricExpand

Arnica (Asteraceae) phylogeny revisited using RPB2: complex patterns and multiple d-paralogues.
The region coding for the second largest subunit of RNA polymerase II (RPB2) was explored for resolving interspecific relationships in Arnica and lower level taxa in general. The region between exonsExpand
