Embodiment 1

[0037] A process for extracting rhizoma glucoside from leaves of Huang Qi, comprising the following steps:

[0038] S1: Pulverize the leaves of Huang Qi and pass through a 50-mesh sieve to obtain the powder of Huang Qi leaves;

[0039] S2: Add 82% ethanol 7 times its weight to the Huangqi leaf powder prepared in step S1, reflux extraction twice under water bath conditions, each extraction time is 2.3h, combine the extract after the extraction is complete, and adjust the pH of the extract value to 5, the temperature is controlled at 78°C, decolorized and impurity removed by activated carbon for 1 hour, and a decolorized solution is obtained after filtration;

[0040] S3: Concentrate and dry the primary decolorization solution obtained in step S2 to obtain an extract extract, which is dissolved in water at 50° C. with 5.8 times the volume of the extract extract, extracted twice with anhydrous ethyl acetate solvent, and continued to use Anhydrous ethyl acetate was subjected to c...

Embodiment 2

[0045] A process for extracting rhizoma glucoside from leaves of Huang Qi, comprising the following steps:

[0046] S1: Pulverize the leaves of Huang Qi and pass through a 40-mesh sieve to obtain Huang Qi leaves powder;

[0047] S2: Add 6 times the weight of 75% ethanol to the Huangqi leaf powder prepared in step S1, reflux extraction twice under water bath conditions, each extraction time is 2.5h, combine the extract after the extraction is complete, and adjust the pH of the extract value to 4.8, the temperature is controlled at 75°C, decolorized and impurity removed by activated carbon for 1.2h, and filtered to obtain a decolorized solution;

[0048]S3: Concentrate and dry the primary decolorization solution obtained in step S2 to obtain an extract extract, which is dissolved in water at 45° C. with 5.5 times the volume of the extract extract, extracted twice with anhydrous ethyl acetate solvent, and continued to use Anhydrous ethyl acetate was subjected to crystallization ...

Embodiment 3

[0053] A process for extracting rhizoma glucoside from leaves of Huang Qi, comprising the following steps:

[0054] S1: Pulverize the leaves of Huang Qi and pass through a 60-mesh sieve to obtain Huang Qi leaves powder;

[0055] S2: Add 8 times the weight of 84% ethanol to the Huangqi leaf powder prepared in step S1, reflux extraction under water bath conditions for 3 times, each extraction time is 2h, combine the extract after the extraction is complete, and adjust the pH value of the extract To 5.2, the temperature is controlled at 82°C, decolorized and removed by activated carbon for 0.6h, and filtered to obtain a decolorized solution;

[0056] S3: Concentrate and dry the primary decolorization solution obtained in step S2 to obtain an extract extract, which is dissolved in water at 55° C. with 6 times the volume of the extract extract, extracted 3 times with anhydrous ethyl acetate solvent, and continued to use Anhydrous ethyl acetate was crystallized three times, and the...

Abstract

The invention discloses a process for extracting engelhardia roxburghiana glycosides from engelhardia roxburghiana leaves, and belongs to the field of technologies for extracting effective components from engelhardia roxburghiana leaves. The process for extracting the engelhardia roxburghiana glycosides includes steps of smashing, primary decolorization, coarse crystallization, secondary decolorization, macroporous adsorption resin separation and purification, concentration crystallization, drying and the like. The process has the advantages that the extraction yield of the engelhardia roxburghiana glycosides extracted by the aid of the process is higher than 58.92%, the purity of the engelhardia roxburghiana glycosides is higher than 98.24%, and requirements on the engelhardia roxburghiana glycosides to be used as qualitative and quantitative reference substances can be met by the purity.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of extracting active ingredients from leaves of huang qi, and in particular relates to a process for extracting radixol from leaves of huang qi. [0003] 【Background technique】 [0004] Huang Qiye is the dried leaf of Huang Qi, a plant of the family Juglandaceae, which is distributed in Guangdong, Guangxi, Yunnan and other provinces, and the resources are quite rich. It has the effect of clearing heat and relieving pain. It is used to treat cold, fever, hernia and abdominal pain. It is often used as tea in folks to prevent high blood pressure and lower blood fat. The leaves of Huangqi are rich in radixol, which has anti-inflammatory effects [RuangnooS, Jaiaree N, MaNachuchit S, Panthong S, Thongdeeying P, Itharat A.An in vitro inhibitory effect on RAW 264.7cells by anti-inflammatory compounds from Smilax corbulariaNaunth.Asian Pac J Allergy Immunol. 2012; 30(4): 268-274.]. However, Smilax chinensis...
