Embodiment 1

[0026] Take 100 grams of ling vanilla, wash away the sand with water, and pulverize after air-drying; add 1 liter of 70% ethanol solution each time, heat and reflux extraction 3 times, each time for 1 hour; combine the three extracts according to the conventional method, concentrate under reduced pressure, and recover Ethanol until there is no alcohol smell. After diluting the concentrated solution and water at a ratio of 1:1 to 1:5, fully absorb with D101 or D201 or D301 macroporous adsorption resin; wash the adsorbed resin with water until the effluent is nearly colorless, and then use The ethanol solution with a concentration of 70% was eluted, and the eluate was collected; after the eluate was dried, 8.2 grams of the crude vanilloid saponin was obtained, and oleanolic acid was used as a contrast, and the vanillin-glacial acetic acid-perchloric acid system was used to significantly Color and measure the saponin content to be 28.3%; The saponin crude product is heated and dis...

Embodiment 2

[0028] Take 100 grams of ling vanilla, wash away the sand with water, air-dry and pulverize; add 1 liter of water each time, heat and reflux extraction 3 times, the time is 2 hours, 1 hour, 1 hour in turn; combine the three extracts, concentrate under reduced pressure, The concentrated solution is fully adsorbed with a macroporous adsorption resin; the adsorbed resin is washed with water until the effluent is close to colorless, and then eluted with a 60% ethanol solution to collect the eluate; after the eluate is dried, vanilla saponin is obtained Crude product 5.0 grams, with oleanolic acid as contrast, adopt vanillin-glacial acetic acid-perchloric acid system to develop color and measure saponin content and be 20.8%; Saponin crude product is heated and dissolved with 80 milliliters of 100% methanol, after cooling, filter, and filtrate After concentration, methanol was recovered; the concentrated solution was dried to obtain 3.2 grams of refined vanilla saponin, the saponin c...

Embodiment 3

[0030] Take 100 grams of ling vanilla, wash away the sand with water, air-dry and pulverize; add 1 liter of 50% ethanol solution each time, and extract 3 times with ultrasonic assistance, each time is 0.5 hours; combine the three extracts, concentrate under reduced pressure, and recover ethanol Until there is no alcohol smell, the concentrated solution is diluted with an appropriate amount of water, and then fully adsorbed with a macroporous adsorption resin; the adsorbed resin is washed with water until the effluent is nearly colorless, and then eluted with a 70% ethanol solution to collect the eluate; After the eluent was dried, 7.0 grams of the crude vanillin saponin was obtained. Using oleanolic acid as a contrast, the vanillin-glacial acetic acid-perchloric acid system was used for color development and the saponin content was determined to be 25.2%; the saponin crude product was mixed with 80 ml 95% ethanol was heated and dissolved, filtered after cooling, the filtrate wa...

Abstract

The invention provides a white crystalline powdered lysimachia foenum-graecum hance saponin extract having more than or equal to 30 percent of saponin, and discloses an extraction process of the extract. By taking lysimachia foenum-graecum hance as a raw material, the extraction process comprises the following steps of: extracting solvent, concentrating, performing resin absorption, performing resin decoloring by washing, eluting with alcoholic solution, collecting eluent, drying, obtaining a crude lysimachia foenum-graecum hance saponin product, heating to dissolve the crude lysimachia foenum-graecum hance saponin product by using alcohol, concentrating, drying and obtaining the white crystalline powdered lysimachia foenum-graecum hance saponin extract having more than or equal to 30 percent of saponin. The extraction process has the advantages of simple process, low production cost, high saponin yield, sufficient and reasonable utilization of the big polar part of the lysimachia foenum-graecum hance, and expanded sources of triterpenoid saponis.

Description

technical field [0001] The invention relates to chemical industry, in particular to vanilla saponin extract with saponin content ≥ 30% and its extraction process. Background technique [0002] Lysimachia foenum-graecum Hance (Lysimachia foenum-graecum Hance) is a plant of the genus Locustaceae in the family Primulaceae. Dayao Mountain in Jinxiu, Guangxi is an important production area of ​​lysimachia foenum-graecum Hance. Ling vanilla has a special aroma and is known as the "King of Incense". It is a precious natural spice, and its essential oil is known as "liquid gold". With chemical and other industries. In addition, ling vanilla is also a kind of precious Chinese herbal medicine. Its stems and leaves can be used as medicine. It tastes pungent, sweet, and warm in nature. Abdominal pain, eczema, impotence, menstrual pain, cold-damp beriberi, traumatic abscess, altitude sickness, etc. have significant effects. Therefore, the spirit vanilla has a very broad application pr...
