摘　　要：[目的]为了获得质量较好的芹菜茎的总RNA,为后续分子生物学试验提供基础。[方法]试验对1种RNA提取方法(Trizol法)和2种RNA提取试剂盒(RNA prep Pure Plant Kit法、RNA simple Total RNA Kit法)方法进行比较研究。[结果]RNA prepPure Plant Kit方法得率低,且OD260/OD280值低于1.8,Trizol法OD260/OD230高于2.0,且得率低于RNA simple Total RNA kit法。只有RNA simple Total RNA kit法提取的RNA质量最好,得率最高。[结论]与Trizol法和RNA prep Pure Plant Kit法相比,RNA simple Total RNA Kit法提取的芹菜茎总RNA得率高,完整性好,凝胶电泳泳道无杂质,可以满足半定量RT-PCR的试验需要。[ Objective ] In order to obtain better quality total RNA in the stalk of celery and lay the foundation for subsequent molecular biology experiments. [ Method] One RNA extraction method（ Trizol method） and two RNA extraction kits （RNA prep Pure Plant Kit method, RNA simple Total RNA Kit method） were compared. [ Result] The yield of RNA prepPure Plant Kit is low, OD260/OD280 value is lower than 1.8, OD260/OD230 of Trizol method is higher than 2.0, the yield is lower than RNA simple Total RNA kit method. RNA extracted by RNA simple Total RNA kit has the best quality and the highest yield. [ Conclusion] The results showed that the Tfizol method was better than two RNA extraction kit method, the total RNA isolated with Trizol method had high integrity, high yield, good stability, and no pollution in the gel electrophoresis track. And then could meet the needs of the semi-quantitative RT-PCR test.
