OBJECTIVE: To study the content of magnoflorine in main species of Epimedii Herba. METHOD: Ultrasonic extraction, HPLC analysis. RESULT: The content of magnoflorine of Epimedium leaves range between 0.0029% and 1.688%. CONCLUSION: The content of magnoflorine of Epimedium show large differences between species but relatively stable within the species, E. koreanum Nakai is the highest one and E. brevicornu is the lowest.
