Objective: To comprehensively study the various factors affecting the quality of Epimedium medicinal materials produced in Guizhou, and to propose methods for the quality control of Epimedium medicinal materials and to study the sustainable use of Epimedium resources. Methods: The contents of icariin and total flavonoids were determined by HPLC and ultraviolet spectrophotometry on epimedium samples of different species, origin, medicinal parts and phenophase. Results: Different kinds, different producing areas, different medicinal sites and different phenological phases directly affected the quality of Herba Epimedii. Conclusion: The quality of some epimedium produced in Guizhou meets or exceeds the standards of the Chinese Pharmacopoeia (2000 version). Epimedium’s medicinal materials are harvested from the flowering stage to the fruiting stage, and the quality is good.
