摘要: 运用硅胶、凝胶和高效液相色谱进行分离纯化,根据理化常数和波谱数据鉴定化合物的结构。从中药枳壳中分离并鉴定了7个环肽成分:环-(亮氨酸1-异亮氨酸2-丙氨酸3-苏氨酸4-甘氨酸5-苏氨酸6-苯丙氨酸7)(1 )、环-(甘氨酸1-亮氨酸2-缬氨酸3-亮氨酸4-脯氨酸5-丝氨酸6)(2)、环-(亮氨酸1-亮氨酸2-脯氨酸3-酪氨酸4-甘氨酸5-丝氨酸6-脯氨酸7)(3)、环-(甘氨酸1-甘氨酸2-亮氨酸3-亮氨酸4-亮氨酸5-脯氨酸6-脯氨酸7-苯丙氨酸8)(4)、环-(脯氨酸-丙氨酸)(5)、环-(丙氨酸-异亮氨酸)(6)、环-(丙氨酸-亮氨酸)(7)。除2和4外,其余环肽均为首次从中药枳壳中分离得到。

Abstract: Seven cyclopeptides were isolated and purified from the immature fruits of Citrus aurantium L.by silica gel,Sephadex LH-20 and HPLC. Their structures were determined on the basis of spectroscopic data as Cyclo-(Leu1-Ile2-Ala3-Thr4-Gly5-Thr6-Phe7) (Citrusin I) (1), Cyclo-(Gly1-Leu2-Val3-Leu4-Pro5-Ser6) (2), Cyclo(Leu1-Leu2-Pro3-Tyr4-Gly5-Ser6-Pro7) (Citrusin III) (3), Cyclo-(Gly1-Gly2-Leu3-Leu4-Leu5-Pro6-Pro7-Phe8) (4),Cyclo-(Pro-Ala) (5), Cyclo-(Ala-Ile) (6), Cyclo-(Ala-Leu) (7). All compounds except 2 and 4 were isolated from this plant for the first time.
