Study of technological parameters and the numerical indicators of the quality of crude materials of canadian goldenrod herb (Solidago canadensis L.)

The article presents the results of a study of technological parameters (specific mass, bulk mass, volume mass, porosity, quantity cavities between particles, free volume of a layer of the crude materials and coefficient of absorption of solvents) and individual the numerical indicators of the quality (moisture; ash residue: total and insoluble in 10% solution of hydrochloric acid; chopped crude materials; extraneous materials) of the Canadian goldenrod herb. The content of extractive substances was determine. The obtained data will be used in the technological process in the production of extraction preparations.
