Extraction and isolation of high-quality RNA from Polygonatum cyrtonema Hua. is the basis of research on gene expression, regulation and genetic engineering. For screening the best method of total RNA extraction from different tissues of P. cyrtonema, total RNA was extracted from rhizomes, stems, leaves and flowers of P. cyrtonema by six methods that were Trizol method, CTAB-isopropanol method, RNA pure plant kit CTAB-LiCl method, hot phenol method and improved hot phenol method respectively. The concentration and quality of RNA were analyzed using Subordinate function method. The results showed that the improved hot phenol method was the most ideal for RNA extraction among the six methods. The RNA bands of different tissues of P. cyrtonema were complete and clear, the OD260/OD280 and OD260/OD230 values were between 1.8 and 2.1, the extraction concentration values were between 77.16 and 185.72 µg/g. This study provide a reference for extracting high-quality total RNA from P. cyrtonema.
