title: [The determination of the somatostatin content in insulin substances].
abstract: 30 different lots (batches) of insulin substances ("Pharmachim" Ltd.) are analysed and the contents of somatostatin is established. The middle quantitative values and the standard deviations are specific. Though that monocomponent and bovine conventional insulin substances pertain to groups of different purity they exhibit highest purity but also greatest variability, while single-peak and porcine conventional insulins show less purity but these groups are more homogenous.
