Abstract

The invention discloses a method for preparing motherwort herb paste. In the preparation method, active ingredients of motherwort herb are extracted by replacing a decoction method with the diaphragm filter-press circular extraction separation integrated technology, so a process can be simplified, the production period is shortened substantially, the production energy consumption is reduced, environmental protection and the utilization of waste residues are facilitated, and the recovery rate of the active ingredients is increased greatly.

Description

Technical field [0001] The invention is a method of preparation of a Chinese medicine preparation in the field of pharmaceuticals. Background technique [0002] China Pharmacopoeia 2010 edition of a record: Motherwort paste is a decoction made of motherwort through processing, which has the effect of promoting blood circulation and menstrual menstruation. It is used for irregular menstruation caused by blood stasis.Pure and postpartum bleeding time is too long; the postpartum uterine recovery is incomplete to see the above -mentioned evidence.The preparation method is to chop the motherwort, add water to boil twice, 2 hours each time, combine decoction, filter out, the filter fluid concentrates to the relative density of 1.21-1.25 (80 ° C);200g, heating and dissolving, mixing, condensed to the prescribed relative density, that is.In the above methods, the effective ingredients of motherwort are used to extract motherwort. There are problems such as long extraction time, high extr...
