Recovery cont

Data have been obtained concerning the stability of ampicillin in human stool specimens. Sixty-four to eighty-four percent of the ampicillin was recovered after 3-4 week storage of the stool-buffer blend in dry ice. A recovery cont control consisting of the sample stool-buffer blend dosed with a known amount of ampicillin was prepared for each sample. When a correction is made based on the recovered penicillin from the control, full recovery of ampicillin and stability through 3 weeks is obtained from the stool-buffer mixture . When ampicillin was incubated with the fecal flora of rats and tested for antibiotic activity, only 36.7% of the ampicillin activity was left after 4 hours . ... 

The recoveries of clomeprop and its metabolite DMPA in soil after extraction with acetonitrile-water (4 1, v/v) by HPLC/UV (234 nm) are >90% The recoveries of propanil and its metabolite, 3,4-dichloroaniline, in soil are 95 and 76%, respectively, by Soxhlet extraction and LC/PAD determination. Diflufenican is added to soil in the range 0.002-0.008 mg kg to validate the method developed by Conte et al. The average recovery from the soil by this method is 92 5%.
