Determination of Niacinamide in Pharmaceutical Preparations

Journal of Pharmaceutical Sciences, 1969
A method for the isolation of niacinamide from multi-component pharmaceutical preparations by partition chromatography between a diatomaceous earth-water column and chloroform followed by measurement of UV absorbance at 262 mμ is proposed. A second method using the color produced by the niacinamide in the column eluate with bromothymol blue in ...

Biocatalysis in pharmaceutical preparation and alteration

Current Opinion in Chemical Biology, 2006
The term 'synthetic biology' is being used with increasing frequency to describe the biocatalytic generation of small molecules, either via stepwise biotransformation or engineered biosynthetic pathways. The flexibility of this newly coined term encompasses the historically separate fields of natural product biosynthesis and metabolic engineering. This

Citywide pharmaceutical preparation for bioterrorism

American Journal of Health-System Pharmacy, 2001
One community's efforts to become pharmaceutically prepared for an attack with biological agents is described. In response to recent bioterrorist activities, including a local scare in 1999 involving anthrax, the pharmacy department at Deaconess Medical Center in Spokane, Washington, was asked to develop a plan for bioterrorism preparedness.

CZE determination of somatostatin in pharmaceutical preparations

Journal of Pharmaceutical and Biomedical Analysis, 2000
We propose a simple and accurate method for CE quantitative determination of somatostatin in pharmaceutical preparations. The method is specific for somatostatin as indicated by the resolution between the analyte and the analogue peptides which differ from somatostatin by one aminoacid. The linearity range is from 0.02 to 0.35 mg/ml.
