The invention provides a preparation method of particles in the formula of
salvia miltiorrhiza bunge and a quality detection method thereof. The preparation method comprises the following steps:
grinding the
salvia miltiorrhiza bunge and extracting by two steps; firstly, adding
alcohol, heating, extracting, spraying,
drying and collecting powdered extract; secondly, adding water, heating, extracting, spraying,
drying and collecting powdered extract; wherein the powdered extracts obtained by the two steps are added with auxiliary materials; and then adding proper water, granulating and
drying to obtain a product. The method is simple, is low in cost and is suitable for industrial production. The detection method comprises part or whole items of characters, inspection, identification and content measurement, wherein the identification is carried out on the
salvia miltiorrhiza bunge by using contrast drugs of the
salvia miltiorrhiza bunge, and the content measurement is the content measurement of
tanshinone IIA and / or content measurement of
salvianolic acid B. The adopted identification is simple in method and strong in specificity; the content measurement is simple in method, high in accuracy and good in
repeatability, and provides detection indexes, detection means and technical method and the like for production units and detection organizations, so that the production can be better guided, and the control of the production technique is more strict and reasonable. In the production process of products, the quality detection method can effectively control the quality of the products, thus ensuring clinical effects and safety of the particles in the formula of the
salvia miltiorrhiza bunge.
