摘　要：

通过对两种miRNA提取方法——一步法和多步法进行比较研究, 以期获得较高质量的蒙古黄芪不同器官的miRNA。实验结果表明, 两种方法均可用于蒙古黄芪miRNA提取, 二者存在着不同的优缺点, 多步法提取成功率较高但步骤繁琐, 相比之下一步法实验条件要求严苛但步骤简单、快捷省时, 提取的蒙古黄芪miRNA完整性好, 可以满足荧光定量PCR等进一步实验需要。

Abstract:

In order to obtain better quality miRNA in different parts of Astragalus membranaceus var. mongholicus, two miRNA extraction methods (one-step method and multi-step method) were compared. The results showed that these two methods had different advantages and disadvantages, but both of them could be used for miRNA extraction. Multi-step method had higher success rate with cumbersome steps, one-step method needed strict experimental conditions but fast and time-saving, the miRNA isolated with one-step method had high integrity which could be used for quantitative RT-PCR and so on.

Key words: miRNA extraction; Astragalus membranaceus var. mongholicus; one-step method; multi-step method
