Five alkaloids were isolated from the epigeal part of Oxytropis myriophylla. Three alkaloids were identified as N-benzoyl-beta-phenylethylamine, N-trans-cinnamoyl-beta-phenylethylamine, N-cis-cinnamoyl-beta-phenylethylamine and the structures of two new alkaloids were elucidated to be N-benzoyl-beta-hydroxyphenylethylarnine(2), N-trans-cinnamoyl-beta-hydroxy-phenylethylamine(5). The absolu.te structures were established by modified Mosher method.
