Polyamine Analysis

High-pressure liquid chromatography analysis of polyamines in bone narrow from leukemic and nonleukemic subjects demonstrated increased concentrations of putrescine, spermidine, and spermine associated with increased cellularity. The most striking abnormality was the marked elevation of putrescine. Bone marrow polyamine analysis may be an adjunct for evaluation of leukemia patients.

Juice Concentrate

Three hundred twenty-eight (328) apple, pear, and mixed fruit products including juices, sauces, purees, jellies, diced apples, and apple pulps from 38 Australian producers were analyzed for patulin using the technique of high pressure liquid chromatography analysis. Patulin was detected in 75 of 258 juice and juice concentrate samples ranging from 5 to 50 μg/L and in 73 samples ranging from 51 to 1130 μg/L. Of 70 samples other than juices, patulin was detected in 18 samples at levels below 50 μg/kg of patulin. The detection limits for patulin in juice and other products were 5 μg/L and 5 μg/kg, respectively.

Isopenicillin N

In a cell-free system prepared by lysis of protoplasts of Cephalosporium acremonium mutant M-0198, isopenicillin N was converted into a penicillinase-resistant material that behaved like deacetoxycephalosporin C on high-pressure liquid chromatography analysis. This activity was found to be unstable to storage at -80 degrees C; 70-80% of the activity was lost after 1 day.
