Pharmaco-technological and thermogravimetric researches of burnet roots in optimization of the process of obtainment of extract dry

Abstract

The article presents the results of examination of the pharmaco-technological properties of burnet roots as required for optimization of the technological process of obtaining the dry extract. Dependence of the amount of extractive substances on the degree of grinding of the medicinal herbal raw materials has been examined, the weight loss upon drying and the absorption coefficient of the extraction solvent have been specified, the parameters of specific, volumetric and bulk weights have been calculated, such technological parameters as porosity, porous-ness have been calculated. Upon examination of the thermal conduct of burnet roots, absence of signs of the herbal constituents’ degradation, under the temperature conditions provided by the process of the dry extract production, has been found.
