PURPOSE:Sulfur containing peptide C antibiotic and sulfur-containing peptide D antibiotic. Characteristics of C antibiotic are as follows: elementary analysis C=49.41%, H=3.91%, N=13.72%, S=14.40%; molecular weight 1100-1400; melting point 284-286 deg.C; specific rotation [alpha]2D2=+75+-5 (C=0.4, pyridine); color reaction, positive to potassium permanganate reaction, etc.; solubility, easily soluble in pyridine, etc. and insoluble in benzene;etc. Characteristics of D antibiotic are as follows: C=47.06%, H=3.41%, N=12.90%, S=14.22%; molecular weight 1100-1400; melting point 285-287 deg.C; specific rotation [alpha]2D2=+53+-5 (c=0.9, pyridine); color reaction, positive to potassium permanganate reaction; et
