Five alkaloids were isolated from the epigeal part of Oxytropis myriophylla. Three alkaloids were identified as N-benzoyl-β-phenylethylamine, N-trans-cinnamoyl-β-phenylethylamine, N-cis-cinnamoyl-β-phenylethylamine and the structures of two new alkaloids were elucidated to be N-benzoyl-β-hydroxyphenylethylarnine(2), N-trans-cinnamoyl-β-hydroxy-phenylethylamine(5). The absolu.te structures were established by modified Mosher method.
从多叶棘豆地上部分分离得到5种生物碱。其中3种生物碱被鉴定为N-苯甲酰基-β-苯乙胺、N-反式肉桂酰基-β-苯乙胺、N-顺式肉桂酰基-β-苯乙胺，另外两种新生物碱的结构被确认为N-苯甲酰基-β-羟基苯乙胺（2）、N-反式肉桂酰基-β-羟基苯乙胺（5）。其绝对构型通过改进的莫舍尔方法确定。
