Technique for preparing fufang danshen pian

Abstract

The invention relates to a new preparation technology of compound salvia tablets, comprising the steps that: (1) the salvia is taken and is put in a flash extractor together with ethanol, extracted for 5 to 20 minutes, and then centrifugated, filtered, the filtered liquid is decompressed to recycle the ethanol for spare; (2) the residue as well as water are put into the flash extractor and extracted for 5 to 20 minutes, centrifugated, and the extracted liquid is concentrated to clear plaster with a relative density of 1.02 to 1.12 (60 DEG C), the salvia fine powder is obtained by spraying and drying; (3) the super micro-powder of notoginseng is obtained by the super-micro pulverization of the notoginseng; (4) grains are made by the filtered liquid after the ethanol is recycled in the step (1), the salvia fine powder in the step (2) and the super micro-powder of the notoginseng in the step (3) as well as supplementary materials and dried, the borneol is ground finely and evenly mixed with the grains, pressed into pill and packed. The salvia extraction procedure provided by the invention adopts a historrhexis technology without heating, the active ingredient content in the obtained salvia tablets is remarkably increased; the notoginseng is finely crushed into super-micro powder in order to favor the absorption of the active ingredient. The treatment effect is great and the energy consumption is low.
