摘要: 从中药王不留行(Vaccaria segetalis)种子中分离并鉴定了 4个环肽化合物,分别命名为王不留行环肽 A,B,C,D(vaccarins A,B,C,D),其中王不留行环肽 A为新环肽化合物。其结构通过光谱和化学方法分别确定为:Vaccarin A一cyclo-Trp-Ala^1-Gly-Val-Ala^2),vaccarin B一cyclo-(Pro-Gly-Leu-Ser-Phe^l-Ala-Phe^2),vaccarin C一cyclo-(Pro^1-Gly-Tyr-Val-Pro^2-Leu-Trp),vaccarin D-yclo-(Pro-Val^1-Trp-Ala-Gly-Val^2).

Abstract: From the seeds of Vaccaria Segtalis, a well-known traditional Chinese medicine named "wang bu liu xing", four cyclopeptides vaccarins A-D were isolated in which only vaccarin A is a new cyclopeptide. Their structures were elucidated by spectral and chemical methods as vaccarin A—— cyclo--(Trp-Ala -Gly- Val- Ala vaccarin B ——- cyclo--Pro-Gly- Leu Ser-Phe- Ala--Phe), vaccarin C——cyclo-(Pro --Gly- Tyr- Val-Pro-Leu-Trp),ccarin D- rtyclo-(Pro-Val-Trp-Ala-Gly-Val).
