Spraying methyl jasmonate before harvesting can significantly increase the content of icariin in an important leaf medicinal herb, Epimedium sagittatum, by activating the expression of genes involved in flavonoid synthesis pathways
We recommend spraying a solution of MeJA at a concentration of 1500 µmol·L<sup>- 1</sup> before harvesting E. sagittatum leaves, and harvesting after 24 h can achieve a rapid increase in the content of active components in a short period of time. This study confirmed the effectiveness of MeJA treatment in enhancing the icariin content and herb quality of E. sagittatum and provided a feasible biotechnological solution for enhancing the quality of E. sagittatum during the harvesting period.
