A novel plant growth regulator, pironetin was isolated from the culture broth of Streptomyces sp. NK10958. The structure of pironetin was determined to be (5R,6R)-5-ethyl- 5,6-dihydro-6-[(E)-(2R,3S,4R,5S)-2-hydroxy-4-methoxy-3,5-dimethyl-7- nonenyl]-2H-pyran-2-one by FAB-MS, 1H and 13C NMR, COSY, COLOC, DEPT, IR, X-ray crystallographic analyses and adapted Mosher's method.
一种新型植物生长调节剂——哌罗菌素，是从链霉菌属NK10958的培养液中分离得到的。通过快原子轰击质谱（FAB-MS）、核磁共振氢谱（¹H NMR）、核磁共振碳谱（¹³C NMR）、化学位移相关谱（COSY）、远程化学位移相关谱（COLOC）、无畸变极化转移增强法（DEPT）、红外光谱（IR）、X射线晶体学分析以及改良的莫舍尔法，确定哌罗菌素的结构为(5R,6R)-5-乙基-5,6-二氢-6-[(E)-(2R,3S,4R,5S)-2-羟基-4-甲氧基-3,5-二甲基-7-壬烯基]-2H-吡喃-2-酮。
