Embodiment 1—16

[0028] Embodiment 1-16 prepares Lie dang extract

Embodiment 1

[0029] Example 1: Select 1 kg of clean purple flower as a medicinal material and crush it into a coarse powder, pass through a 20-mesh sieve, use 4 times of water as the extraction solvent, decoct and extract once for 2 hours, filter the extract to remove insoluble impurities, concentrate, and dry Afterwards, the Liedang extract is obtained with a yield of 26.1% and a total glycoside content of 6%.

Embodiment 2

[0030] Example 2 or choose a clean purple flower column as medicinal material 1 kg and cut it into a section less than 5 cm, extract twice with 12 times the amount of 30% ethanol under reflux, each time for 60 minutes, combine the extracts, and centrifuge the extracts to remove insoluble impurities. Concentrate and dry to obtain Lietang extract with a yield of 28.9% and a total glycoside content of 8.9%.

Abstract

The invention relates to a broomrape extract, broomrape total glycoside and broomrape polysaccharide, which are prepared by adopting water or methanol or ethanol as an extracting solvent and by means of decoction, reflux, diacolation, immersion or supersound. The broomrape extract and the broomrape total glycoside are subjected to further pharmacodynamic experiments such as oxidation resistance, fatigue resistance, senile dementia resistance and hepatitis resistance; the application of the broomrape extract, the broomrape total glycoside and the broomrape polysaccharide in the aspect of preventing and treating diseases is elaborated; and a novel approach and novel application are provided for further utilization of broomrape plants.

Description

technical field [0001] The present invention relates to plant extracts and their preparation methods and uses, in particular to the extracts of Liedang and their preparation methods and the further purified total glycosides and polysaccharides of Liedang. Uses of glycosides and glycosides in the prevention and treatment of diseases. Background technique [0002] There are 13 genera and 180 species of Liedangaceae, which are mainly produced in the northern temperate zone of Eurasia. Liedang is the largest and contains 140 species. In my country, there are Cistanche, Cistanche, Wild Wildflower, Cydonia and Liedang There are 10 genera and about 35 species, many of which have good medicinal value, such as: the Cistanche genus Cistanche mainly produced in the saline-alkali land and sandy land in Northwest my country, and the Cistanche genus Cistanche mainly produced in the Changbai Mountains in Northeast my country Cistanche deserticola and Liedang which are widely distributed in ...
