本文介绍用FABMS法或SIMS法研究抗生素柱晶白霉素、4"-酰螺旋霉素、Shengjimycins的质谱裂解规律。用MS数据和13C NMR(COM,DEPT)数据鉴别该分子式和结构式。该方法有利于寻找新的抗生素。
In this paper mass spectral fragmentation of antibiotics leucomycins, 4"-acylspiramycins and Shengjimycins were reported by FABMS and SIMS. The molecular formula and strucure of the antibiotic were idetified by mass data and 13C NMR(COM. DEPT)data. It is a useful method for finding new Antibiotic.
