Assessment of classification ability for rbcL and trnL barcode in some Stemonaceae samplescollected from northern Vietnam

Stemona tuberosa Lour. a precious medicinal plant that belongs to the Stemonaceae family, has high applicability human life. Extracts from leaves or roots of this herb contain many bioactive compounds with great value for both medical application and economy. However, there is not enough data related evaluation classification species in Vietnam. Therefore, study, authors used DNA barcoding method evaluate at molecular level four samples northern Vietnam compared other reference sequences family GenBank based on two chloroplast barcodes rbcL trnL. The primary results genetics distance analysis phylogenetic trees showed close relationship between studied (sequenced GenBank). trnL 1100 bp length also proves better ability than rbcLregion 600 length. These outcomes would be first promising step further studies about herbs, thus contributing scientific research practical demands as conservation.
