摘要
从云南民间重要的药用植物金铁锁 (PsammosilenetunicoidesW .C .WuetC .Y .Wu)的根中分离得到 2个新的天然环二肽以及 2个新的环八肽 :金铁锁环肽A和B (psammosileninsAandB) .它们的结构经光谱方法鉴定为cyclo (-Ala -Ala - ) ,cyclo (-Val -Ala - ) ,cyclo (-Pro1-Phe1 -Pro2 -Phe2 -Phe3-Ala -Pro3-Leu)和cyclo (-Pro1 -Gly -Phe1 -Val-Pro2 -Phe2 -Thr-Ile - ) .
From Psammosilene tunicoides W. C. Wu et C. Y. Wu, two new natural cyclic dipeptides and two new cyclic octapeptides (named psammosilenins A and B) were isolated. Their structures were determined as cyclo(-Ala-Ala-), cyclo(-Val-Ala-), cyclo(-Pro 1-Phe 1 -Pro 2-Phe 2-Phe 3-Ala-Pro 3-Leu-) and cyclo(-Pro1-Gly-Phe 1-Val-Pro 2-Phe 2-Thr-Ile-) by spectroscopic methods respectively.
