摘要:
采用测定粗品肝素纳260、280 nm光吸收和蛋白质的三氯乙酸浊度法,有效地解决了质量和效价的判断问题.结果显示,光吸收和蛋白质浊度与样品的效价成反比关系,可根据所归纳的光吸收和蛋白质浊度的6个程度,判断30~140 USP u/mg的样品,鉴定样品质量的优劣程度.

Estimations of Quality and valence of Crude Sodium Heparin
Abstract:
It is difficult to determine the quality and to estimate the valence range of crude sodium heparin by observing its color, appearance and hardness. However, through measuring the absorption of its solution at 260 and 280nm, and determining its turbidity and precipitate of protein ofter adding trichloroacetic acid, the above problems could be solved. It was found that the valence of crude sodium heparin was inversely proportional to the absorption of its solution at 260 and 280nm. The similar relationship between the valence and the turbidity was found. Six grades of crade sodium heparin could be estimated according to the absorption at 280 and the turbidity of its solution.
