Objective To verify the existence of microRNAs (miRNAs) extracted from fresh ginseng decoction. Methods Fresh ginseng was prepared into decoction according to the conventional method. The miRNA were extracted from the condensed ginseng decoction by plant microRNA extraction kit. Then miRNA were treated by DNase I and subjected to agarose gel electrophoresis and Agilent 2100 bioanalysis. MiR-159 and miR-6135, which were highly expressed in ginseng, were selected and verified by real-time quantitative PCR to detect the expression in the decoction. Results Ginseng miRNA were successfully extracted from fresh decoction. MiR-159 and miR-6135 were expressed in fresh decoction with lower levels than those of fresh ginseng. Conclusion miRNAs stably existed after processing, and retained some stability after high-temperature treatment. The findings provide a valuables basis for the further studies on ginseng miRNAs.
