Abstract
An isolated plant-functional microRNA or an extract containing said plant-functional microRNA, a preparation method therefor, and an application thereof are provided. The plant-functional microRNA originates from the endogenous microRNA of a plant, is present in a water-soluble and/or fat-soluble extract of said plant, and is capable of regulating non-plant target-genes.
Claims11
A method for preparing a pharmaceutical comprising:
- extracting MIR2911 from a plant using water to obtain an extract containing MIR2911;
- and
- mixing the extract containing MIR2911 with a carrier acceptable in pharmaceutics to form said pharmaceutical,
- wherein the extract containing MIR2911 is a water extract of Lonicera japonica
- and contains 0.01-100 nM MIR2911, and
- the extract containing MIR2911 has a MIR2911 content that is greater than or equal to 70% of a total amount of microRNAs in the extract containing MIR2911.
A method for treating a viral cold comprises administering a microRNA molecule MIR2911 at a concentration of 0.01-100 nM to a subject in need thereof.
A method for treating a viral cold comprises administering a pharmaceutical comprising an extract containing MIR2911 and a carrier acceptable in pharmaceutics to a subject in need thereof,
