Abstract

The new macrolide antibiotics were isolated by silica gel chromatography. They showed a UV absorption maximum at 240 nm. Deltamycins A1, A2 and A3 were demonstrated to be new macrolide antibiotics on the basis of their physicochemical properties whereas deltamycin A4 was identified as carbomycin A.

摘要

新型大环内酯类抗生素通过硅胶柱色谱法分离得到。它们在240nm处有最大紫外吸收。根据其理化性质，证明δ霉素A1、A2和A3为新型大环内酯类抗生素，而δ霉素A4被鉴定为碳霉素A。
