Method for extracting total RNA from plant tissue rich in polysaccharides and polyphenols and secondary metabolites

The invention provides an extration method of plant RNA by utilizing guanidinium isothiocyanate-chloroform extractive and Tris purification. The invention improves traditional guanidinium isothiocyanate method, adopts the two steps of chloroform extration after cracking and phenol-adding for purification, and respectively extract high-quality total RNA from the leaf blade and seed case of red-skinned pears, the leaf blade, fruit flesh and seed case tissues of grapes, the fruit of strawberries and the callus of arnebia euchroma. The extraction buffer liquid in the method contains guanidinium isothiocyanate, sodium dodecyl sarcosinate, sodium citrate, soluble polyvinylpyrrolidone and beta-mercaptoethanol, which can not only crack plant cells efficiently and release RNA, but also effectivelyinhibit the activity of RNA enzyme, and can also prevent the oxidation of phenolic compounds and suppress the interference of secondary metabolites. In the second step, Tris purification is utilized for crude extraction of RNA solution, which can eliminate the polysaccharides and protein which can coprecipitate with RNA. The invention is simple in operating steps, economic and practical, good in stability, and suitable for extracting high-quality total RNA from plant tissue rich in polysaccharides and polyphenols and secondary metabolites.
