Embodiment 1

[0029] Take 40Kg of the whole plant of Chonglou plant, grind it to coarse powder, add 280 liters of 70% alcohol each time, heat reflux extraction at 70°C for three times, filter through a 40-mesh stainless steel screen, combine the filtrates, recover the alcohol under reduced pressure, and obtain a wet extract 6.2 Kg, specific gravity 1.1. Add 62 liters of 40% alcohol to the wet extract to dissolve, filter and separate with a ceramic membrane with a pore size of 0.2um; take another 45 liters of 40% alcohol, and dialyze and wash the intercepted solution three times. The last cut-off solution (about 13 liters) was dissolved with 50 liters of 95% alcohol, and then 150 grams of gac was added, stirred at room temperature for 8 hours, filtered through filter paper, and the filtrate obtained 1156 grams of white extract after decompression and recovery of alcohol, and then added 5 Heat reflux with acetone and degrease for 2 hours, filter through filter paper to obtain a white precipit...

Embodiment 2

[0033] The other processes are the same as in Example 1 except that 10 times the weight of water-containing alcohol is added to the coarse raw material powder, and the mixture is heated to reflux at 90°C.

Embodiment 3

[0035] Other processes are the same as in Example 1 except that 4 times the weight of water-containing alcohol is added to the raw material coarse powder, and the mixture is heated to reflux at 60°C.

Abstract

A process for preparing the common saponin of Chinese paris rhizome includes such steps as extracting, separating and purifying, and features that the extracting in alcohol, membrane filtering, resin adsorbing, resin decoloring, decoloring with activated carbon and defatting with acetone are combined. Its advantages are high extracting rate and low cost.

Description

technical field [0001] The invention relates to the extraction of active ingredients of traditional Chinese medicines, more specifically, the invention relates to a preparation method of total saponins of Pachyphyllum pachyrhiza. Background technique [0002] To sum up, there are ethanol extraction method, n-butanol extraction method and adsorption resin method for the existing total saponins of Parisia saponins. These methods, the product that makes is brown, brown or light brown, and outward appearance color and luster is darker; Anti-hygroscopicity is poor, saponin content and extraction rate are lower. These deficiencies are the technical problems to be solved urgently in the preparation of the total saponins of Chonglou. Contents of the invention [0003] The object of the present invention is to provide a preparation method of total saponins of S. sinensis in view of the deficiencies in the prior art. This method can ef...
