Abstract

The invention discloses a method for preparing pulse activating decoction. In the method, instead of a percolation process, membrane pressure filtration circulating extraction and separation combined technique is used to extract the active ingredients of medicinal materials in a formula, so the production period is shortened greatly, environment protection and slag utilization are promoted and the recovery rate of the active ingredients is increased greatly.

Description

technical field [0001] The invention belongs to the field of pharmacy and relates to a preparation method of a traditional Chinese medicine preparation. Background technique [0002] The Chinese Pharmacopoeia 2010 Edition records: Shengmai Drink has the effects of nourishing Qi and rejuvenating the pulse, nourishing yin and promoting body fluid, and is clinically used for both Qi and Yin deficiency, palpitations, shortness of breath, and spontaneous sweating. The prescription is 100g of red ginseng, 200g of Ophiopogon japonicus, and 100g of schisandra. Its preparation method is to crush red ginseng, Ophiopogon japonicus and Schisandra chinensis into coarse powder, use 65% ethanol as a solvent, soak for 24 hours, then percolate, collect about 4500ml of percolation liquid, concentrate under reduced pressure to about 250ml, let it cool, add water Dilute with 400ml, filter, add 300ml of 60% syrup and appropriate amount of preservatives, adjust the pH value to the specified rang...
