Abstract

The invention discloses a preparation technology of a Lysimachia christinae Hance freshly squeezed vacuum-dried powder decoction piece. The preparation technology comprises 1) pretreatment, 2) squeezing juicing, 3) mixing and filtration, 4) concentration, 5) drying granulation and 6) packaging. The preparation technology reduces a decoction piece size, maximally retains polar and non-polar active ingredients in Lysimachia christinae Hance, prevents an active ingredient loss and drug quality reduction caused by decoction piece processing, storage and transportation at present and reduces the risk of drug contamination. The preparation technology has a great significance to ensure the quality stability and clinical safety and effectiveness of Lysimachia christinae Hance.

Description

technical field [0001] The invention relates to the field of Chinese herbal medicines, in particular to a freshly squeezed vacuum-dried powdered decoction piece of Desmodium sativa and a preparation process thereof. Background technique [0002] Money grass, also known as fairy sitting on grass, ground centipede, centipede grass, copper coin grass, etc. It is the dry whole herb of Primulaceae plant Guoluhuang, which is distributed in the provinces south of the Yangtze River in my country and Taiwan Province; it is sweet, slightly bitter, and cool in nature; it belongs to the liver, gallbladder, kidney, and bladder meridians; it clears away dampness and heat, relieves stranguria, reduce swelling. For hot stranguria, sandy stranguria, astringent and painful urination, jaundice and red urine, carbuncle and furuncle, poisonous snake bites; hepatolithiasis, urinary tract calculi. The whole plant contains flavonoids: quercetin, isoquercitrin, quercetin-3-O-glucoside, etc. [000...
