Abstract
Some Sauropus and Breynia species were investigated for phytochemicals as well as
their DNA profile for genetic relationships. S. bicolor and S. thorelii are important
species that contain eudesmin concentrations of 36.445 mg and 32.190 mg from 2 g
fresh leaves and 1.5 g dried leaves, respectively, and 10.620 mg from 2 g dried leaves
was revealed via high-performance liquid chromatography (HPLC) analysis. The
genetic relationships calculated via inter simple sequence repeat (ISSR) dendrogram
construction, as shown by similarity indices, revealed Breynia and Sauropus separation
accuracies, with S values of 0.71-0.81 between genera, S values of 0.76-0.85 at the
interspecific level of Breynia and S values of 0.69-0.80 in the Sauropus species, in
agreement with the criteria for category distinction. Barcodes with rpoB and trnH-psbA
spacer regions can be used to identify some species of the two studied genera.
