Though the ivy (Hedera nepalensis K. Koch.) has long been utilized in traditional medicine, its genome information is very limited. For plants, an effective method of DNA extraction is a very important step which greatly affects subsequent genetic analyses. In this study, four different methods of DNA extraction from dry leaves were used. A comparison of different protocols resulted in the yield of extracted DNA that ranged from 10.5 to 437.4 ng/μl and with a purity ranged from 1.8 to 2.2. Based on the PCR results of GBSSI gene, Gene JET Plant Genomic DNA Purification Mini Kit is the most optimal extraction method for Vietnam ivy’s dry leaves. A preliminary analysis of the phylogenetic tree based on the GBSSI marker showed that ivy growing in a number of northern mountainous provinces of Vietnam belonged to the H. nepalensis K. Koch species. The high - quality total DNA will allow us to amplify different DNA markers, providing valuable genetic information to preserve and develop medicinal resources in Vietnam.
