Paper chromatography of antifungal antibiotics.
Paper chromatography is very helpful in the identification and comparison of antibiotics, but very few results from the application of this technique have been published so far. The awakening of interest in the search for antibiotics which are active against fungi pathogenic to plants and animals makes the investigator aware of the scant information that is available to help characterize such a...
متن کاملQuantitation of antibiotics by high-pressure liquid chromatography: cephalothin.
A technique for quantitative determination of cephalothin and desacetylcephalothin in serum using a method based on high-pressure liquid chromatography is described. Both compounds were quantitatively extracted from serum by using dimethylformamide. After separation of the drugs by reverse-phase chromatography and detection by ultraviolet light absorption at 254 nm, serum concentrations of ceph...
متن کاملHigh performance liquid chromatography of saframycins, heterocyclic quinone antitumor antibiotics.
Saframycins are members of a new family of antitumor antibiotics isolated from the streptothricin-producing strain of Streptomyces lavendulae No. 314. Ten components1~5), A (1), B (2), C (3), G (4), H (5), Y3 (6), D (7), F (8), R (9) and S (10), have been isolated from the culture broth and their structures have been established as shown in Fig. 1. All saframycins bear the dimeric quinone skele...
متن کاملSeparation of aminoglycosidic antibiotics by gas-liquid chromatography.
Eighteen aminoglycosidic antibiotics and their degradation products, containing 2-deoxystreptamine as a commonmoiety, were separated by gas-liquid chromatography. The largest compounds examined included the pentacyclic lividomycins A and B. These compoundswere separable from each other either as pertrimethylsilyl derivatives or N-trifluoroacetyl pertrimethylsilyl derivatives on a single column ...
متن کاملQuantitation of antibiotics using high-pressure liquid chromatography: tetracycline.
A method for quantitative determination of tetracycline in serum, using high-pressure liquid chromatography, is reported. After extraction of the drug from serum, using methanol-trichloroacetic acid solution, tetracycline was separated by reverse-phase chromatography. Quantitation of tetracycline was based on a linear relationship between peak heights in the chromatograms and known concentratio...
