Embodiment 1

[0019] (1) Dried the acacia peel and crushed to 30 mesh, then submerged in distilled water with 40 times the mass, extracted with ultrasonic wave at a power of 4000w for 50min, and then added biological enzymes (neutral protease, fiber Sulfase and pectinase in an equal volume ratio), then carry out enzymatic hydrolysis at 50°C and pH 7 for 4 hours, and then obtain the filtrate and filter residue by filtration;

[0020] (2) Repeat the operation of step (1) for 5 times with the obtained filter residue, and combine the filtrate to obtain the saponins extract;

[0021] (3) The saponins extract obtained in step (2) was concentrated under reduced pressure at 50°C to a thick paste, and then dried to obtain the total saponins extract of saponins; the extraction rate was 43%, and the total saponins content was 68.2%;

[0022] (4) Add 30 mass times of sulfuric acid solution with a mass concentration of 1.0% to the total saponin extract obtained in step (3), then heat and reflux for 6 ho...

Embodiment 2

[0024] (1) Dry the acacia peel and crush it to 20 meshes, then immerse in 50 times the mass of ethanol with a volume concentration of 50%, extract with ultrasonic wave at a power of 6000w for 20min, and then add biological enzymes at 0.5% of the total volume (a mixture of neutral protease, cellulase and pectinase in an equal volume ratio), and then carry out enzymatic hydrolysis at 40°C and pH 8 for 2 hours, and then obtain the filtrate and filter residue by filtration;

[0025] (2) Repeat the operation of step (1) for the obtained filter residue 4 times, and combine the filtrate to obtain the saponins extract;

[0026] (3) The saponins extract obtained in step (2) was concentrated under reduced pressure at 50°C to a thick paste, and then dried to obtain the total saponins extract of saponins; the extraction rate was 38.5%, and the total saponins content was 75.3%;

[0027] (4) Add 20 mass times of sulfuric acid solution with a mass concentration of 0.5% to the total saponin e...

Embodiment 3

[0029] (1) Dry the acacia peel and crush it to 40 meshes, then immerse in 30 times the mass of ethanol with a volume concentration of 70%, extract with ultrasonic wave at a power of 2000w for 60min, and then add biological enzymes at 0.5% of the total volume (a mixture of neutral protease, cellulase and pectinase in an equal volume ratio), and then carry out enzymatic hydrolysis at 30°C and pH 7 for 5 hours, and then obtain the filtrate and filter residue by filtration;

[0030] (2) Repeat the operation of step (1) for the obtained filter residue 3 times, and combine the filtrate to obtain the saponins extract;

[0031] (3) The saponins extract obtained in step (2) was concentrated under reduced pressure at 50°C to a thick paste, and then dried to obtain the total saponins extract of saponins; the extraction rate was 32%, and the total saponins content was 80.1%;

[0032] (4) Add 25 mass times of sulfuric acid solution with a mass concentration of 0.8% to the total saponin ext...

Abstract

The invention discloses a preparation method for a high-purity gleditsia sinensis natural surfactant. The preparation method comprises the following steps: conducting ultrasonic-assisted extraction on gleditsia sinensis peel; adding a biological enzyme for enzymolysis, and then carrying out filtration to obtain a gleditsia sinensis extraction liquid; carrying out vacuum concentration at 50 DEG C to obtain thick paste, and then drying the thick paste to obtain a gleditsia sinensis total saponins extractive; purifying the gleditsia sinensis total saponins extractive to obtain the gleditsia sinensis natural surfactant. The preparation method has the advantages that the extraction rate and the purity of the gleditsia sinensis natural surfactant are improved; through the adoption of ultrasonic-assisted biological enzyme extraction, the content of total saponins in the obtained gleditsia sinensis total saponins extractive reaches 50-80%, and the aglycone purity reaches 80-95%; no toxic or harmful reagent is adopted in the preparation process; the obtained gleditsia sinensis natural surfactant can be used as an additive for drugs, cosmetics and commodities.

Description

technical field [0001] The invention relates to a preparation method of a high-purity saponins natural surfactant, belonging to the technical field of biological extraction and processing. Background technique [0002] Acacia, alias saponins, belongs to Fabaceae, Acacia ( Gleditis ia sinensis Lam.). my country's honey locust resources are abundant, mainly distributed in Yunnan, Sichuan, Guizhou and other places. Acacia pods contain more than 30% saponin, which is the woody plant resource with the highest saponin content found. Yunnan acacia is produced in Kunming, Songming, Dayao, Lufeng, Binchuan, Yangbi, Huize, Yongsheng, Weixi, Gongshan, Wenshan, Yanshan, Mengzi, Jianshui, Pingbian, Jingdong and other places. The wood of Acacia dianthus is relatively solid, the heartwood is reddish brown, and the sapwood is light yellowish brown. It is used for construction, furniture and agricultural tools. The decoction of pods is used to replace soap for washing. The endosperm is ...
