Effects of different propagation modes on accumulation of active components in Epimedium koreanum / 中草药

ABSTRACT

Objective: To study the effects of the different propagation modes on the accumulation of active components in Epimedium koreanum, and to provide the guidance for the standardized cultivation of E. koreanum. Methods: The contents of total flavonoids and icariin in the different propagation modes of E. koreanum were measured by HPLC and ultraviolet spectrophotometry. Results: The contents of the active components had the significant difference in E. koreanum of different propagation modes. By cultivating under the 50% man-made shade and under the sun, the contents of the active components were far higher and more stable, but little impacted by harvest time and growth year. Conclusion: When cultivated under the 50% man-made shade, E. koreanum is the best of the four propagation modes.
