Abstract A new cyclopeptide alkaloid, sanjoinine-G1, has been isolated from the seeds of Zizyphus vulgaris var. spinosus . The structure and absolute configuration has been established by spectroscopic analysis and the circular dichroism exiton-coupling method, as N -[( S )-( N ′, N ′)-dimethylphenylalanyl]-cyclo[ O -(2 S ,3 S )- β -oxyleucyl-( S )-leucyl-(2-mino-(1 R )-hydroxyethyl)- p -phenyl].
摘要 从Zizyphus vulgaris var. 的种子中分离到了一种新的环肽生物碱sanjoinine-G1。棘刺。通过光谱分析和圆二色性激子耦合方法确定了结构和绝对构型,为N -[( S )-( N ', N ')-二甲基苯丙氨酰基]-环[ O -(2 S ,3 S ) -β-氧基亮氨酰-(S)-亮氨酰-(2-氨基-(1R)-羟乙基)-对-苯基]。
