Problems solved by technology

In the early 1990s, Ye Yucong and others observed the anti-hypoxic effect of Tangut Qinglan from the water extract and volatile oil of Tangut Qinglan. [2，3，4] Later, some people successively studied the pharmacological basis of anti-hypoxia of Tangut green orchid water extract. [5，6] , but so far, the research on the anti-hypoxic effect of Tangut green orchid is limited to the report of the anti-hypoxic effect of the total extract such as water extract

Embodiment 1

[0018] Example 1 Extraction method of Tangut green orchid extract 1

[0019] Crush the whole herb of Tangut Qinglan, pass through a 40-mesh sieve, and set aside.

[0020] Put 250 g of the above-treated Tangut green orchid powder into four times the volume of 75% ethanol solution, heat and reflux repeatedly, combine the extracts, evaporate the extracts to remove ethanol with a rotary evaporator, and dissolve the obtained extract with warm water , the resulting liquid was washed with petroleum ether until the transparent color of the petroleum ether phase no longer changed. Then, the aqueous phase was repeatedly extracted with n-butanol or amyl alcohol saturated with water until the extract was evaporated to dryness and the residue was very small, and the extracts were combined, concentrated by distillation under reduced pressure to obtain solid total saponins.

Embodiment 2

[0021] Example 2 Extraction method of Tangut green orchid extract 2

[0022] Crush the whole herb of Tangut Qinglan, pass through a 40-mesh sieve, and set aside.

[0023] Heat and reflux 250g of the above-treated Tangut green orchid powder with four times the volume of methanol solution to extract, dissolve the extract in a small amount of methanol after distillation, add dropwise to acetone several times the volume of alcohol, and shake while adding , the total glycosides were precipitated into a powder, suction filtered, and dried to obtain solid total glycosides.

Embodiment 3

[0024] Example 3 The extraction method of Tangut green orchid extract 3

[0025] Crush the whole herb of Tangut Qinglan, pass through a 40-mesh sieve, and set aside.

[0026] Extract 250g of the above-treated Tangut Qinglan powder with four times the volume of 75% ethanol solution, concentrate the extract, add freshly calcined magnesia to the concentrated alcohol solution, mix well, dry, grind, and use methanol or Extract with ethanol, concentrate the extract to obtain total glycosides in solid state.

Abstract

An application of the general aglycone of Dracocephalum tanguticum Maxim (DtM) in preparing the medicine or health-care food for preventing and treating anoxia is disclosed. Said general aglycone is prepared from the herb of DtM through pulverizing, extracting in ethanol or methanol, defatting with petroether, and extracting with n-butanol.

Description

technical field [0001] The invention relates to a Tibetan medicine tangut qinglan extract, more precisely, the invention relates to the extraction method of the tangut qinglan total saponin extract and its application in anti-hypoxia. Background technique [0002] my country's plateau area accounts for 33% of the country's total area, of which plateaus above 3,000 meters above sea level account for 16% of the country's total area, and the population living in plateau areas is about 60 million. Therefore, to protect the vast number of workers in plateau areas and improve their quality of life, Delaying premature aging and preventing acute and chronic altitude sickness are the top priorities in altitude medicine at present, and the central link of all these is to improve the body's ability to withstand hypoxia. The purpose of the present invention is to develop high-efficiency, low-toxic anti-hypoxic products to make up for the serious shortage of anti-hypoxic products in my co...
