自东北淫羊藿（ＥｐｉｍｅｄｉｕｍｋｏｒｅａｎｕｍＭａｋａｉ）的地上部分，分离得到４个单体化合物，根据理化数据和光谱分析鉴定为：金丝桃甙（ｈｙｐｅｒｉｎ）（１），淫羊藿甙－Ⅱ（ｉｃａｒｉｓｉｄⅡ）（２）．淫羊藿甙－Ⅰ（ｉｃａｒｉｓｉｄⅠ）（３）和淫羊藿甙（ｉｃａｒｉｉｎ）（４）．其中，金丝桃甙在本种植物中首次分离得到，同时，我们又利用１Ｈ－１Ｈｃｏｓｙ和１３Ｃ－１Ｈｃｏｓｙ谱，对原文献中化合物２部分Ｃ信号的归属进行了修正，另外，药理实验结果表明：淫羊藿甙（ｉｃａｒｒｉｎ）对氢化可的松造成的小鼠阳虚有一定的拮抗作用．
Four monomeric compounds were isolated from the aerial parts of Epimedium koreanum Makai. Based on physicochemical data and spectral analysis, they were identified as hyperin (1) and icarisid II (II). 2). Epimedium - I (icarisidI) (3) and Epimedium (icariin) (4). Among them, Hypericum perforatum was isolated for the first time in this plant. At the same time, we used the 1H-1Hcosy and 13C-1Hcosy spectra to modify the assignment of the C signal of compound 2 in the original literature. In addition, pharmacological experiments showed that : icarrin has a certain antagonistic effect on the yang of mice caused by hydrocortisone.
