preparation example Construction

[0024] A preparation method of Panax notoginseng glycosides in Panax notoginseng glycosides granules, comprising the steps of:

[0025] (1) Crush the notoginseng medicinal material into coarse powder, put it into a multifunctional extraction tank, add 6-8 times the amount of water, then add the notoginseng medicinal material and 0.1%-0.5% emulsifier of the total amount of water and mix with it , the added emulsifier is any one of 0.1%-0.5% Tween-80 or Tween-20, then reflux extraction twice, each time for 1 hour, and the extract is collected;

[0026] (2) Adjust the Ph value of the collected extract to 7-8, after filtering the precipitate, take the filtrate, adsorb and chromatograph through the macroporous adsorption resin, and use 700-850 liters, 50-70% ethanol to elute Collect the eluate twice, recover ethanol, concentrate the eluate at 60-70°C, steam pressure 0.10-0.15Mpa, vacuum degree -0.05Mpa--0.08Mpa, and then concentrate the concentrated The paste is spray-dried to obt...

Abstract

The invention discloses a method for preparing panax notoginseng saponins from panax notoginseng saponins particles. The method comprises the following steps: (1) smashing the pseudo-ginseng medical material into coarse powder, putting the powder into a multi-functional extraction tank, adding 6-8 times of water, adding an emulgator, mixing uniformly, and then reflux extracting twice for one hour each time, and collecting the extracting solution; (2) adjusting the pH value of the collected extracting solution to be 7-8, after filtration and precipitation, taking the filtrate, performing adsorption and chromatography through macroreticular resin, eluting once or twice using ethanol with the concentration of 50-70%, collecting the eluant, after recovering ethanol, condensing under reduced pressure, and performing spray drying to obtain powder extract. By adopting the method provided by the invention to extract pseudo-ginseng, the yield of panax notoginseng saponins is increased, the extract yield is increased by 30% or above, the extraction time and the number of extraction times for preparing panax notoginseng saponins are reduced, the production period for extracting pseudo-ginseng is greatly shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to a preparation method for extracting effective components in plants, in particular to a production method for extracting total glycosides as effective components of Panax notoginseng, and belongs to the field of traditional Chinese medicine preparation. Background technique [0002] Panax notoginseng is the dry root tuber of the perennial herbaceous plant Sanqi of Araliaceae, also known as Tianqi, Tiansanqi, Shenqi, Shensanqi, Jinbuhuan, Dianqi, etc. Warm in nature, sweet in taste and slightly bitter, it is the main raw material of "Yunnan Baiyao". Panax notoginseng has various nourishing and strengthening effects such as anti-fatigue, hypoxia resistance, aphrodisiac, anti-aging, blood sugar lowering and improving the body's immune function. Panax notoginseng glycosides are the active ingredients contained in Panax notoginseng. Modern pharmacological studies have proved that panax notoginseng glycosides have the functions of sto...
