Embodiment 1

[0028] The method for extracting yam element from plant yam of the present embodiment comprises the following steps:

[0029] 1) Take 35kg of yam skin (the source is waste from the production of Chinese yam decoction pieces in Jiaozuo, Henan Province), crush it, add an extractant made by mixing ethanol and water, heat it to 60°C and extract it under reflux for 4 times, adding 300L of extractant each time (approximately 8.57L of extractant is added per 1kg of yam skin), the weight percentage of ethanol in the extractant is 70%, and the extraction time for each time is 3h, 3h, 2h, and 2h respectively. The obtained extracts are combined and then concentrated under reduced pressure To no ethanol, get the concentrated solution of Chinese yam bark extract;

[0030] 2) Take the concentrated solution obtained in step 1), extract it three times with petroleum ether, add the petroleum ether and the concentrated solution in equal volume each time, combine the extracted organic phases, co...

Embodiment 2

[0034] The method for extracting yam element from plant yam of the present embodiment comprises the following steps:

[0035] 1) Take 300g of yam Lingyuzi (yam beans, sourced from Jiaozuo, Henan), crush them, add an extractant made by mixing ethanol and water, heat to 80°C and extract 3 times under reflux, adding 2L of extractant each time (per 1kg Add about 6.67L of extractant to yam yam yam, the weight percentage of ethanol in the extractant is 75%, each extraction time is 3h, 2h, 2h respectively, the obtained extracts are combined and then concentrated under reduced pressure to no ethanol to get yam yam Concentrates of extracts;

[0036] 2) Take the concentrated solution obtained in step 1), extract it twice with ethyl acetate, add the amount of ethyl acetate equal to the volume of the concentrated solution each time, combine the extracted organic phases, concentrate under reduced pressure to remove ethyl acetate, and obtain an extract ;

[0037] 3) Add the extract obtain...

Embodiment 3

[0040] The method for extracting yam element from plant yam of the present embodiment comprises the following steps:

[0041] 1) Take 500g of yam skin (the source is Jiaozuo, Henan), crush it, add an extractant made by mixing methanol and water, heat to 70°C and extract 5 times under reflux, and the amount of extractant added each time is 2L (per 1kg of yam skin Add extractant 4L), the weight percentage of methanol in the extractant is 65%, each extraction time is 3h, 3h, 2h, 2h, 2h respectively, the obtained extracts are combined and then concentrated under reduced pressure to no methanol, to obtain Concentrate of yam bark extract;

[0042] 2) Take the concentrated solution obtained in step 1), extract it twice with n-hexane, add the same volume of n-hexane and the concentrated solution each time, combine the extracted organic phases, concentrate under reduced pressure to remove n-hexane, and obtain an extract;

[0043] 3) Add the extract obtained in step 2) into a methanol-...

Abstract

The invention discloses a method for extracting batatasin from plant Chinese yam. The method comprises the following steps of (1) weighing the plant Chinese yam, smashing the plant Chinese yam, adding an extracting agent prepared by mixing low carbon alcohol and water, carrying out heating reflux extraction, concentrating the obtained extract to remove the low carbon alcohol, and thus a concentrated solution or an extract A; (2) weighing the concentrated solution or the extract A, adding a weak-polarity or medium-polarity organic extracting agent to carry out extraction, taking the organic phase obtained by extraction, concentrating to remove the organic extracting agent to obtain an extract B; and (3) adding the extract B in a first organic solvent, dissolving and filtering, cooling a filtrate, crystallizing and filtering to obtain a batatasin crude product. The method for extracting batatasin from the plant Chinese yam is simple in process, convenient for operation and low in energy consumption. The solvent can be used circularly, has no environment pollution and high extraction rate, and can obtain the batatasin with the content higher than 99%. The method is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of plant active ingredient extraction, and in particular relates to a method for extracting yam element from plant yam. Background technique [0002] Yam (Dioscorea opposita Thunb) is a plant of the genus Dioscorea in the family Dioscorea, twining herbaceous vines; its tubers are long cylindrical, vertically growing, up to 1m long, white in section when fresh, rich in viscosity, and white and powdery when dry, as Common ingredients and herbs. The stems and leaves of this plant (yam vine) and the bulbils between the leaf axils (Zero Yuzi, also known as yam beans) are also available for medicinal purposes. As a traditional Chinese medicine, yam is sweet and flat in nature; functions and indications: nourishing the spleen, nourishing the lungs, strengthening the kidney, and benefiting the essence; mainly treating diarrhea due to spleen deficiency, edema due to lack of food, cough and asthma due to lung deficie...
