A New Tetraazacyclododecane of Epimedium sagittatum
摘要
A new tetraazacyclododecane, 2-acetyl-1,4,7,10-tetraazacyclododecane (1) and nine known compounds were isolated from the stems of Epimedium sagittatum (Berberidaceae). The structure of the new tetraazacyclododecane was determined by interpretation of the spectroscopic data.
