Embodiment 1

[0026] Embodiment 1 (claim 1)

[0027] (1) Put 1 kg of sugarcane fruit in a pulverizer and grind it to 60 mesh, then add 1.5L of ethanol solution with a concentration of 65% and soak for one day, recover the soaking solution, and add 1.5L of 65% ethanol solution to the sugarcane fruit again. % ethanol solution for immersion for one day, and combine the two immersion solutions to obtain the extract;

[0028] (2) Concentrate the above extract under reduced pressure at 60°C for 2 hours to remove ethanol to obtain an extract, measure the relative density of the extract to be 1.25, then add water to the extract and stir continuously, and measure with a hydrometer at the same time until the relative density is obtained 1.10 extract dilution;

[0029] (3) Adopt the macroporous resin that model is R8-18 to extract the medicinal extract dilution that obtains through macroporous adsorption resin, be 100:20 (g / g) respectively according to the consumption of macroporous resin consumption...

Embodiment 2

[0030] Embodiment 2: (increase alcohol precipitation)

[0031] (1) Put 1 kg of sugarcane fruit in a pulverizer and grind it to 55 mesh, then add 1.5L of ethanol solution with a concentration of 65% and soak for one day, recover the soaking solution, and add 1.5L of 65% ethanol solution to the sugarcane fruit again. % ethanol solution for immersion for one day, and combine the two immersion solutions to obtain the extract;

[0032] (2) the extract was concentrated under reduced pressure at 60°C for 2 hours to remove ethanol to obtain an extract, and the extract obtained was first added to 3L of 95% ethanol solution in volume, left to stand for 24 hours, and the precipitate was removed to get the supernatant of the extract. It is 1.25 to measure the relative density of the supernatant of the extract, then add water to the supernatant of the extract and stir continuously, and measure with a hydrometer simultaneously until obtaining a dilution of the extract with a relative densit...

Embodiment 3

[0034] Embodiment 3: (increase ultrafiltration)

[0035] (1) Put 1 kg of sugarcane fruit in a pulverizer and grind it to 50 mesh, then add 1.5L of ethanol solution with a concentration of 65% and soak for one day, recover the soaking solution, and add 1.5L of 65% ethanol solution to the sugarcane fruit again. % ethanol solution for immersion for one day, and combine the two immersion solutions to obtain the extract;

[0036] (2) Concentrate the extract under reduced pressure at 60°C for 2 hours to remove ethanol to obtain the extract, measure the relative density of the supernatant of the extract to be 1.25, then add water to the supernatant of the extract and stir continuously, while using the specific gravity Meter measurement, until obtaining relative density is the medicinal extract dilution of 1.10, then above-mentioned medicinal extract dilution is ultrafiltered by the ultrafiltration tube that molecular weight cut off is 3000, and the relative density of the medicinal ext...

Abstract

The invention discloses a preparation method of a pain-relieving arenga pinnata extract. The preparation method comprises the following steps: (1) slicing or grinding arenga pinnata fruits, and performing reflux extraction or soaking extraction with an ethanol solution to obtain an ethanol extracting solution; (2) removing ethanol in the ethanol extracting solution obtained in the step (1) to obtain an extract, adding water for diluting to obtain a extract diluent having a relative density of 1.02-1.21; and (3) extracting the extract diluent with a macroporous resin, washing the resin with water and / or ethanol solution in sequence, eluting with an ethanol solution having a concentration of 60-95%, collecting the eluant until the solution is colorless, and performing vacuum concentration, thereby obtaining the pain-relieving arenga pinnata extract. The pain-relieving arenga pinnata extract obtained by the preparation method has an excellent pain relieving effect and high yield.

Description

technical field [0001] The invention relates to the field of medicine, in particular to sugar palm analgesic extract and its preparation method and application. Background technique [0002] Sugar palm (scientific name: Arenga pinnata (Wurmb.) Merr.), Palmaceae tree, the thorn is relatively strong, 5 meters to 10 meters high, the fruit matures about 2-3 years after flowering, the fruit is nearly spherical, 5-6cm long, 4-5cm in diameter, dark brown outer surface, with white fine hairs, obvious bumps formed by shriveling, and 3 persistent perianths at the base, wide at the bottom and narrow at the top. Sugar palm is a common plant in the south, with a wide distribution and a huge amount of fruit. Sugar palm is generally made into edible products such as sugar palm powder, sugar palm oil tea, sugar palm wine or sugar palm sugar, but its application in the field of medicine has not yet been rationalized. develop. [0003] Among them, the Chinese invention patent with the publi...
