Problems solved by technology

However, due to the limited solubility of saponins in water, and many other non-saponin components in Sapindus chinensis are also soluble in water, such as carbohydrates and proteins, the extraction rate and purity of saponins in water extraction are relatively low.
In addition, due to the strong foaming properties of saponins, it is difficult to distill and concentrate the extract after water extraction, which increases the energy consumption of the drying and dehydration steps
In addition, it is also reported that Sapindus saponin is extracted by water and then purified by alcohol precipitation, ultrafiltration or macroporous adsorption resin, and the purity of Sapindus saponin is greatly improved, but the yield is greatly reduced.

Embodiment 1

[0017] Example 1, after the fruit of Sapindus chinensis is picked, it is dried in an oven at 60° C., peeled, and the pericarp is crushed to 20 mesh with a pulverizer to obtain Sapindus pericarp powder; add 10Kg of Sapindia sapinsia fruit peel powder into the extraction tank , add 50L of water, heat at 60°C, stir, reflux for extraction for 8 hours, separate the solid and liquid to obtain the extract, then add 40L of water, heat at 60°C for reflux for 5 hours, separate the solid and liquid to obtain the extract, combine it with the first extract ; Add 3Kg chitosan to the extract, let it stand at room temperature for purification, and centrifuge to obtain a clarified solution. Use a double-effect rising film evaporator to carry out vacuum distillation on the sapindus saponin clarified liquid, volatilize the water, so that the solid content reaches 20%, and obtain 18L of sapindus saponin concentrated liquid product, and its saponin content is 4%-8%. Dehydrating the sapindus saponi...

Embodiment 2

[0018] Example 2, after the fruit of Sapindus chinensis is picked, it is dried in an oven at 60° C., peeled, and the pericarp is crushed to 5 mesh with a pulverizer to obtain Sapinsia sapinsia peel powder; add 10Kg of Sapinsia sapinsia pericarp powder into the extraction tank , add 50L of water, heat at 30°C for reflux extraction for 7 hours, stir, and obtain an extract by solid-liquid separation, then add 40L of water, heat for 30°C for reflux extraction for 5 hours, and obtain an extract by solid-liquid separation, add 30L of water, heat for 30°C for reflux extraction for 3 hours, solid Separate the liquid to obtain an extract, which is combined with the first and second extracts; 3.5Kg of aluminum sulfate is added to the extract, left to stand at room temperature for purification, and centrifuged to obtain a clarified solution. Use a double-effect rising film evaporator to carry out vacuum distillation on the sapindus saponin clarified liquid, volatilize the water, so that t...

Embodiment 3

[0019] Example 3, after the fruit of Sapindus chinensis is picked, it is dried in an oven at 60°C, peeled, and the pericarp is crushed to 5 mesh with a pulverizer to obtain Sapinsia chinensis peel powder; add 10Kg of Sapinsia chinensis fruit peel powder into the extraction tank , add 50L of water, heat at 40°C for reflux extraction for 4h, stir, and separate the solid and liquid to obtain the extract, then add 30L of water, heat at 40°C for reflux for 3h, separate the solid and liquid to obtain the extract, add 20L of water, heat at 40°C for reflux for 1h, solid The extract was separated from the liquid to obtain the extract, which was combined with the first and second extracts; 2Kg aluminum potassium sulfate was added to the extract, left to stand at room temperature for purification, and centrifuged to obtain a clarified solution. Use a double-effect rising film evaporator to carry out vacuum distillation on the sapindus saponin clarified liquid, volatilize the water, so tha...

Abstract

The invention relates to the extraction of plant fruit active ingredients, and especially relates to a water extraction preparation method of daily chemical sapindoside. The water extraction preparation method of daily chemical sapindoside provided by the invention employs Sapindus peel as a raw material and has the main points: crushing dry Sapindus peel to 5-20 meshes so as to obtain Sapindus peel powder; adding 2-5 times by weight of water, stirring under the constant state of 30-60 DEG C to extract for 2-3 times (each time lasts for 1-8 hours), carrying out solid-liquid separation, and combining extract liquids; adding 1-5wt% of precipitation agent to the extract liquids, standing for purification, and carrying out solid-liquid separation with a centrifuge; and performing vacuum-distilling on a sapindoside supernatant with a double-effect climbing film evaporator, and performing spray-drying and dewatering on the concentrated liquid. The water extraction preparation method provided by the invention is simple in process, does not use organic solvents and lowers investment cost and production cost; and the sapindoside obtained by the water extraction preparation method has the recovery rate more than 75% and the purity of 20-40%.

Description

Technical field: [0001] The invention relates to the extraction of effective components of plant fruits, in particular to a water extraction method of sapindus saponin for daily chemical use, that is, a method for extracting sapindus saponin, the active ingredient in sapindus pericarp, using water as an extractant. Background technique: [0002] The content of saponin in Sapindus fruit peel is very rich (accounting for about 20% of dry matter), it is a kind of natural degradable non-ionic surfactant, its ability to reduce surface tension is even stronger than some synthetic surfactants, At the same time, it also has antibacterial, anti-inflammatory, whitening and other activities. Therefore, Sapindus saponins can be used as surfactants and active ingredients in high-end cleaning products and cosmetics, such as facial cleanser, shampoo, shower gel and other skin care products. [0003] For a long time, most of Chinese Sapindus chinensis is abandoned as waste, and its own val...
