| Abstract: | Buds of Dendrobium contains high levels of polysaccharides which easily combined with RNA,so it was difficult to extract RNA from buds of Dendrobium.In this research,using 1.5%SDS with high salt concentration,the RNA of Dendrobium buds was precipitated by LiCl in order to get rid of polysaccharide.With this method,high quality RNA was get and thus was worth further biological research. |

| Keywords: | Dendrobium buds polysaccharides RNA extracting |
