Abstract
A crystalline mixture of the antibiotics chlorothricin and dechlorothricin was isolated from a strain of Streptomyces antibioticus. By degradation 5‐chloro‐6‐methylsalicylic acid methyl ether (from chlorothricin) and 6‐methylsalicylic acid methyl‐ether (from dechlorothricin) were isolated. Common degradation products of both antibiotics were 2‐deoxy‐D‐rhamniose and an aglycone, C30H38O8, of unknown structure. The antibiotic mixtures was active against GRAM positive bacteria on syntheitc, but not on complex media.
